For irrigating grodan cubes, I'd recommend looking up the GroGuide brochure. Page 6 goes through figuring out full saturation weight, and the mL amounts for each cycle based off slab/block volume.
Not going to lie, you got me into plants. I played sports all my life and due to injuries, working and other stuff, I lost that hobby. It’s been so hard to find a new hobby, but the way you make these videos makes it fun and envious. Ive watched a lot of you tubers that make videos on plants and your knowledge is unmatched. Simple and low cost ideas. Love the vids
Really appreciate this comment.
It’s the most rewarding hobby I’ve undertaken (and keep in mind, I make my own beer)
Glad you caught the bug!
The hybridisation of science, technology and plants is a winning one.
Fully agree that the intersection of science, technology and plants is amazing! It multiplies the learning vectors which makes it super exciting!
You nailed it, over saturation of the grow cube, especially in the early seedling period i.e. first 2 weeks, leading to an anoxic cube . Must have a wet/dry cycle, the very reason that incremental plant grow cube and pot sizing exists. Feeding/watering timings, E.C. values and light intensity should all increase incrementally to match the bio-mass growth of the plant. Could have used air stone(s) in the reservoir to help oxygenate nutrient solution, additionally nutrient solution temperature may have been too high, also depleting O2 content as you are aware. Covering the grow cube tops with even 'loose' panda film is great for stopping algae growth, but will retard the wet/dry cycling of the cube slightly, as you mention regarding the Hydro Cucumber Farm cubes. Making some strategic vent holes in plastic covers may help if required. Notice the melon plants main stem never thickened or increased in girth at the base of the plant or in general, I find this is always a good indication that healthy rhizosphere growth is occurring in the block or any media for that matter and that the plant is up-taking food/water effectively. Environmental air movement (fans) and air exchange (exhausting stale air for fresh) is crucial in maximizing wet/dry cycling of the plant media, while improving overall growth and strengthening of the plant. Great video and explanation of the hydro facility operations. Fantastic time lapse footage as usual. Cheers.
Great reply, I agree and was thinking environmental conditions needed more explanation. The rock wool growing medium usually holds +80% water retention and the grow may have suited smaller burst of nutrient and long oxygen pauses. But ya gotta love Hoocho’s go at this - brilliant. The commercial farmer was a great example of an A1 setup. The end diagnosis was serious root porn mate 🙏buy no Happy ending as we discovered the root didn’t penetrate 🤪
Every grower should know about this channel. The dedication is amazing!
Cheers Mate. Appreciate it!
Been waiting for this one since I saw the picture on Instagram. Loaded with information as usual. 👏👏
You nailed it dude.....cubes way too wet. Fantastic video bro. Keep em coming.
Man, I really enjoy these longer videos of yours showing multiple aspects of grow systems trial and error. I transplanted everything I had grown into my gutter system and last night there was a crazy freeze unexpectedly. I lost a ton of plants and am super bummed.
I just ordered a King Gizzard & the Lizard Wizard vinyl earlier :D
Great job mate, love the insights into your failed and successful grow on the rock cubes as well
That greenhouse is so impressive.
7:00 the way the little tail is spinning around is just hilarious. 😆
Thank-you for sacrificing your two plants for us. Was nice to see the problems that can arise from over watering. Wish you the best, thanks for all your videos. You make my peaked intrest even higher! Sending sunshine from Canada!
Thanks! I grew NFT lettuce, rocket, spinach, and mustard greens throughout the whole winter in our spare bathtub. Not sure how to send you a pic. Your videos were so much help, I ventured into Dutch buckets out in the garden this year and the results are so much better than any soil growing I have done in the past.
Real tour and real information and data! Much better than the shallow doccos from mainstream channels out there! Thanks mate!
I have no idea how people love so much cucumbers.
Amazing Channel for Hydroponics! I never saw this detailed video of showcasing a very large facility and doing the same thing at home! That is wonderfull!
Have you considered wrapping the rock wool cubes in fabric? Total not a hydo thing but it would encourage air pruning if roots and expansion in fine roots back into the block. Your watering change makes sense.
Cucumelons are amazing! Mine took a while to take off but are still growing strong while all the cucumbers have died.
Props on showing the plant die. A lot of people would hide that sort of thing.
Why hide a valuable (and avoidable) lesson.
Also I thought it was super interesting seeing how relatively quickly the plant died once no energy input occurred.
Would’ve thought the dormancy period would be longer...
I guess it’s super unnatural to not receive any light at all for multiple days.
@@Hoocho I agree 100%. That's how we learn, by making screw ups. I just killed a bunch of seedlings by having them too close to a light and they got too hot. Sadly a bit of an expensive screw up. I hear you also, you would think a plant would survive a couple of days without light. In the UK they grow plants by candle light. Some plants are just prima donnas.
@@dodaexploda My reckoning was because the plant was in a high growth stage, had all of its resources tied up and had no margin for error.
@@Hoocho That makes sense to me.
Excellent video👏👏
man hydroponics and KGLW, what a pleasure. great channel,congratulations !!
Brilliant show mate 👍👍 This is a great journey into the many shades of hydroponicing. I’ve just been reading the comments around here, wow much wisdom and much love. Great Thursday thanks to ya show mate and just a Good Friday tommorrow 😷 🍻 from NQ
I quite enjoyed the journey myself.
Feeling the love.
Cheers Sheriff mate!
Danke!
You the Best!
my Guess ,water temp ,water air, no root heater cable,pump on time ?,Thanks Hoocho another Great video well worth the watch
Great tour and great grow lessons, nice work!
amazing
Good stuff
Love your vids brosef!
Detailed quality content and your quite likeable (not in a suss way) lol
Keep it up man
Cheers brother!
Great video as always. I have built in my garden a mini lean-to greenhouse with hydroponic cascade. It was good to see this video to remind me of the airflow and humidity factor that is needed.
With regard to those cubes - far too dense for that type of delicate root network. Your earlier videos that taught me the efficiency of Perlite and vermiculite mix would achieve far greater success. More freedom for the root network, more oxygen free-flow, less water stagnation.
Basically, the simple growing medium using far less equipment to inject pulse and drain works with a suitable ratio. Yes, it is half Kratky and half NFT, but lid covered and suspended in a muslin bag means no algae!
yup cube is too dense that's why the roots are all on the outside.
I tend to agree with Hoocho -- cube seems waterlogged rather than too dense, so the roots are looking for oxygen. Out of curiosity Hoocho, what was your watering schedule/pulsing?
Planing to start hydroponic system larning lots of things from your chanel thank you
Magic cat disappeared at 19:56. Spooky. Rock wool is cool stuff. I have not used the large sizes of rock wool but I know that even the 1 incher holds a ton of water for quite a long time.
I am in Arizona ~ so very, very dry ~ I may test adding some misters to cycle in my test
I know the time lapse is time intensive, but they are awesome. Good job
I enjoy making them. Editing the final product is extremely rewarding. And sharing it with people like yourself who enjoy it really makes the effort worthwhile. Thank YOU Sandra!
@@Hoocho Where can we purchase merchandise? Love your logo. Should be on beer koozies
@@coalinga63 in the description of my videos there’s two links 😊
I was like: Nonono, not the other one!!!
🔥
Roots we're able to get proper oxygen on the outside thats the only reason you nailed it
The water was stuck in the soggy cube because the wrapper was not removed.
Removing the wrapper will also cause the roots to air prune at the sides rather than circle.
Then the air pruned roots will fill out with thousands of roots back to the main root.
I didn’t notice how pollination is achieved. We’re the cucumbers self pollinating or a variety that does not require it? Also you now have me curious about cucamelon! Great video!
MATRIX!!
God damn these songs are good
Try adding a small aquarium air pump connected to a small bubbler rock in the reservoir. Works wonders for DWC where saturation is not an issue. Early in the lifecycle it might allow higher saturation levels of rockwool without negative effects; this way you're less likely to have dangerous dry periods between pulsing. Just mind the humidity when doing this in any enclosed space, because the humid air has to go somewhere after bubbling.
In conjunction with the air pump/stone, add some slots below the rockwool so that mature roots can venture into the reservoir (keep them out of your pump though!). Then you can dial back pulse rate as the plant matures without as much fear of roots drying completely if your pulse time isn't perfect. The dual root zones will give much more resilience to the system.
(Disclaimer: I am not a professional. Only small grow experience. Please research before implementing in any situation where losses are not acceptable.)
p.s. Great video! I love to see learning in progress. (Subscribed)
Great comment! Air pump definitely can’t hurt!
@@Hoocho
If you run the test again try using one grodan cube and one cultilene cube. You will see the difference.. Personally I prefer aero as there`s no media cost and its easy to see what the roots are doing without killing the plant or needing x-ray specs.
Quality content on par with what I've seen on the ABC--would give this two thumbs up if I could!
Thankyou!
Thanks for the excellent video. At 5:08 the cubes where the seeds are sown, what did you soak the grow cubes with? How did you nourish those initial cubes until the seeds germinated?
Did you find out from the hydroponic greenhouse how they pollinate their plants? i thought it wouldnt be insect due to the traps above the plants but wasnt sure.
With cucumber, there are some that can self polinate
I use a hot water geyser drip tray with thick polyester batting from upholstery shop layer in the bottom and my Rockwool goes on top of that. The tray is at an angle and water falls back into the reservoir at the bottom and gets injected on the high side every 3 hours. Roots grow under the polyester. I also put a sheet of panda film over to block light. Roots are aerated as they dry down between cycles.
Hoocho, have you checked the Homegrown Passion You Tube vid?. How they set it up is very interesting.
I might have missed it, but what was the cycle you used to pulse watering?
so.. what cycle time did you end up using and what would you recommend in the future?
Hello, Nice video!!!
I am left with a doubt, how many times/crops can I reuse the same piece of rockwoll before changing it completely?
Hey, I'm curious what camera you used for the time laps. cheers.
Hi Friend this was amazing, May i know the spacing of the rows and between the plants, and each cube has two plant or two stems coming out of one, grated. Secondly i want to know how many infrared cameras are they having per growing zone, is it possible to get the brand name of the Infrared Camera, is it a IR camera or IR radiometer. waiting to hear from you.
I wonder if you can air the rock wool around the sides with a black breathable material that allows roots to hit air much the grow bags that have aerated sides increasing root hair.
Awesome video, gotta say I've been into gardening/hydroponics and aquaponic for a while and it's really nice having an aussie creator that I know I can get the stuff he's recommended at bunnings etc
what about slicing the Big cube into sections, and place air spacers every 1 inch in the "layer cake" so that they can get air wherever the roots are developing?
Just buy a big sack of Cultilene brand mini rockwool cubes (10mm x 10mm x 10mm), they provide the ideal amount of air and moisture.
Those roots look like they were starting to circle under the plastic. Could they be covered from light to tackle the algae but have an air gap to enable some air pruning to the sides? Might encourage the bottom growth into the reservoir more?
what device are you using for this time lapse? 🤩
Which of the bestva lights did you use?
What a great video. Loved watching it. I was hoping to see some cucumelons. Did they actually grow before you sacrificed the plant in the name of science & entertainment? 😅
16 days to grow to that size -- that's insane!
I've watched alot of your videos but I cant find anything about the ph zone for about 60 strawberry plants in my NFT system. Can you point me in the right direction? Thank you
Is that... a kegerator in your office? I'm inspired.
What do you do with the rock wool after you harvest
Hello! Can you share the formula of the nutrition system for cucumbers on your greenhouse? How many NPKCaMg elements to add per ton of water?
G’day Hoocho, can you recommend how best to get in contact with someone from Muirs NSW?
Do they deal well with little guys wanting small orders or do they refer off to others?
Spiders are a good predatory insect.
Was it Dutch greenhouse? Thanks for info!
You just needed a good dryback during the initial rooting of the cube
What is the name of the pump used in this video? Thanks
KGLW and hydroponics oh man
It looks like the roots are acting root-bound. Try taking off the outer film to allow for more evaporation?
What material is the greenhouse roof?
hi hoocho i hope ur going well mate. i just discoverd ur channel but have been following mike vanduse .(sry spelink) one thing he dos is uses masterblend tomato mix. are u aware of an equivlent heare in oz ? ur feedback or a vid on this would be well aprecated.
how many PPM of o2 is maintained in the water using Nanobubble and what is the brand of the Nanobubble machine used
How do you stabilise ph in rockwool slab? It's looks like a mission impossible...All time it is too high. Any "secret sauce"?
Plants grow roots sideways across topsoil, and only have some roots go down deep to tap for the water table. There's no cubes in nature. Your plant will grow as wide as the roots can grow. If you had a deep pot of roots, then each time you water you'll be making different moisture levels. Some roots will be perfect, others will drown, and others will starve for moisture. Keeping your soil flat and shallow and wide helps your plant drink faster and avoid root rot.
Another great video! Is there any special considerations for growing a plant entirely in rockwool? Since the roots are constantly exposed to the rockwool and the alege, is there anything youd watch out for?
Not especially, as in the video just make sure you don’t overwater (with nutrient) as I did.
Rockwool is forgiving (my experience with starter cubes)
@@Hoocho
Try the Cultilene mini rockwool cubes (10mm cubes) and you`ll never go back to using big cubes.
Awesome! So if the feeders are only on for 30 sec at a time, how often do they turn on?
Depends on stage of growth, environmental conditions, and condition the rockwool is in. You want to irrigate just as the rockwool starts to move from moist to dry.
I thought that rockwool from the factory where they make it says it won't absorb water
Was this video sponsored by Cultilene?
Like
maybe Add an air stone to the reservoir to increase O2 in the solution. ?
Better off throwing the seed into the big cube hole and then fill with a plug as it grows. I sprout seeds rip the cube and put them in as low as possible let the root hang out the bottom
Way to wet and you started the little cube inside the big cube to early, you gotta establish the small cube first and air prune the root system of that little cube so roots are exploding, then put them in the big cube and only irrigate as it drys out maybe once every 2-3 days in the beginning maybe longer depending on temps and demand, once they are established in the big cube with roots coming out the bottom they will handle multiple feeding, its a wonder you didnt get root rot .
I grew my hydroponic cucumber with big mason jar. I don’t need any air bubbles or anything. It went well up until the entire plant got eaten by green caterpillar. 😂😂😂
This is a Wilma system??
Same fundamental idea.
I would try to wrap off the plastic on the cube in the very beginning. Those, who like to grow plants in a fabric grow bags, always talk about the air pruning of the roots. They say, that in a plastic pot roots just go round it, but in a fabric they stop growing when they come in to air and start to make new branches inside the grow medium. Just guessing...
Great Vid mate just wondering how long do you run the light for in a 24hr cycle thanks
16-18 hours for most plants
@@Hoocho Awesome thanks mate keep your vids coming😃
The time lapse videos are amazing, when vegans say we all need to turn to plant base its funny how they won't eat animals but when you see the plants grow and move about surely its also cruel to cut them down 🤭. It would be interesting to see what the cost comparison would be from hydro to soil minus the pest asides, once I have time I'm definitely want to try this 👍
what purpose does the rockwool serve if you're clipping? arent the roots better off in the solution?
In his setup, none. Delta cubes and slabs are more suited to drain-waste systems. Moving the emitter to the slab allows the cube to become dry-space as the water table drops to the bottom of the slab, not the cube. A cube sitting on top of a non-similar surface will always cause it to retain a steep water profile regardless of water interval. This is fine for early plants but once a few roots have penetrated the bottom, they should be moved off the tray and onto a slab. Easier and saner to just dunk the entire plant in solution if one isn't going to do all this required work. What the delta cube and slab buy you in a GH is propagation space and lack of needing a recirculating reservoir.
Can I ask what you mean by “clipping”?
Also, this may be a complete oversight and should’ve been a question that I asked...
I assumed that the system in the video was recirculating, are you telling me it’s drain to waste?
@@Hoocho using a string and clips for support. since the plant doesnt need a huge block at the base for support (its supported by the clips and string) whats the point? it seems an unnecessary expense
@@danroden830 the media is meant to give the roots the ideal balance of oxygen, water and nutrients throughout its structure (when properly managed).
It also allows for more fine tune control of temperature (as its insulating) and lets you have wet -dry cycles as I think was mentioned above.
A good base and anchor is important as well.
DWC is fantastic, but it’s quite a different growing condition and comes with different challenges.
Why do the vines twist as the grow higher? They reach out and circle.
They're searching for something they can wrap around for structure
Did they say what their profit margin is?
I'm not sure the injection I to the rock wool is necessary ,I would have allowed cycles of wicking from base by filling a base that has a small drop rate . That way you are wicking then drying out wool forcing air to fill the gaps then refilling with nutrient again. Some other ideas is driving air into the rock wool via some say 5 - 10 mm holes tapped into rockwool say via a core drill . These are just ideas 💡.
Great video again, surprised u don't have more subscribers yet! But maybe consider changing the music during the time lapse. Its getting a bit repetitive. Which greenhouse did u visit? was this a special for you or do they take visitors? I'd love to do a tour! .. .... hope our lockdown ends tomorrow! stay safe!!!
I just rocked up on their door as I drove past. Hence the thongs.
The music is from an open source album to KGATLW. I’d have to find another copyright free album. Open to suggestion.
@@Hoocho Dope Lemon 😁
@@aussiesheriff7079 Does Angus have an Open Source album? I'd definitely mix in some Smooth Big Cat
Hand water when plants become light overflow goes into Reservoir.
I am no expert at all, but one possible interpretation of the root growth trying to escape the Rockwood cube would be that it is not an ideal growing medium. Maybe too dense and m
.
I think the plants simply had everything they needed with those outer roots. No need to send out more roots for more nutrients.
Love the vids, can tell in this one you were watering way too much. Too much algae growth on top. I think the drippers that the facility were using let out less water than your ones. I have some similar to the ones they were using and they restrict the flow of the 3mm tubing quite alot, its not full flow like yours.
What's the name of the Farm?
Maybe the pulse water rate is too aggressive for just two plants? They have 100's of water loving vacuums sucking up the water so they can be more aggressive.
