In this video I tested two hydroponic grow methods to see which consumes less water. This test initially is done without growing any plants for a control. In a future video I will be testing these methods by growing plants.
This video is GOLD!!! Opened many people’s eyes, including my own. Many thanks my friend, well done 💯🙌
I've been growing with LPA for 10 years.
Each of the areo systems i built have 2, 21 site grow chambers with 1 reservoir.
Each system measures 3'x3'. This way I can use 1, 3'x3' LED light.
I built 4 of these areo systems. I run all 4 systems at the same time.
All 2 weeks behind each other.
So i harvest every 2 weeks.
There have been countless times when I was doing something to a system and have forgotten to plug the pump back in.
A lot of times I don't catch it for 24 hours later and I've NEVER lost a plant.
But the precaution I have done, just in case there is a power outage.
I installed a solar system on top of my grow garage.
Just for backup.
But I've also been using it to power my mother and clone room.
So it's been a win win for me.
Your systems look ok. They work for you.
Me personally don't like my roots hanging in the solution all the time.
Yo man, I've seen you commenting to a aeroponics potato growing video! You have some super interesting insights to the aeroponics. You should start making videos of your system. Or can I find you at some forums? Would love to read more of your stuff before I start building my own aeroponic system.
Great testing. Solve my problem too. Thanks.
Great Videos, really appreciate all of the information provided. Could you share where you purchase your Hydroponic supplies? I really liked the black buckets with the hinged lids you used in the Kratky vs DWC pepper test.
Great info, thanks
Great video, thank you, I have a quick question. I have this small 7" square container with lots of action from to two 6" air stones. I have 5 spots for 2" net pots. My question is, Where should I place the end of my clematis cuttings in relationship to my water level. In some holes I'm using just the closed cell foam collars with the bottoms removed on pots others have intact pot with rockwool and collars. my waterline has the bottom 1/2" submerged.
Yes! Another great channel that uses the scientific method as well as we can in a semi-variable environment. Great motivation, great video. Subbed.
Edit: *Hybrid aeroponics. Great information about surface tension. I ebb and flow but am looking into aeroponics. I would have thought the hyvrid aeroponics would evaporate more and I like your logic. my current system is not for leaving more than 2 days so that looks promising. I wonder however about fog type aeroponics or mist? Thanks again!
Great video.
you could try a small internal aquarium filter and set it up so that it agitates the surface of the water some of them allow you to attach a airtube to draw in air as well
Did you build the grow system? Do you have directions to build one?
Do you have the followup video on this one with the growing test Airstone vs Aeroponics?
The hybrid method for me is a bunch of coco around root with a drain and fill with air stones everywhere including in the coco itself so at worst my plants are using water while the coco allows the air roots that are never submersed to breath still even in total power loss at max depth
I currently use an air water pump so my second air pump runs that to fill and i have a auto syphon that drains but if that fails i have a wayer pump every 6 hours
2 air pumps 3 air stones 1 air water pump 1 Water pump
450w of led lights
Been great so far growing some carolina reapers and some passionfruit currently and buying some stuff for doing some outdoor salad dwc/kratky lettuce and pumpkin
I use two 180 degree sprayers in a bucket daisy chained to other buckets with sprayers + air stones in the bottom of each bucket. DWC + Aeroponics.
I use a combination to grow in turbo speed🙂. Roots sit in about 5 inches of water being bubbled. Water misters run 15 min on 15 off with a timer set for the pump . Grow is better than dwc. I use a smaller pump and only two hole. Smaller pump helps water temps. Something about suspended roots in air and dampness really makes growing fun. Also I use beneficial micro's so I never get root rot. Dryer parts of the root ball will have fuzz.
So not fully submerged roots all micros to live and the plant uptake nutes.
how much faster is it, compared to the aeroponic system alone?
Are you going to do a side by side grow, with a fruiting plant to see if there are any yield differences? For example your Kratky method versus DWC.
Jennifer Gomez yes eventually.
Looking forward to it
Right. Thats the only thing that counts.
I'd like to see you compare growth with both methods. I believe you would get faster growth from the outside pump source because of CO2/Oxygen transfer vs the recirculating system that will not bring in more CO2/Oxygen. I know from aquarium experience that supplemental CO2 greatly helps plant growth. I just see the other one as being "stagnant" but with movement.
Josh Blick that’s a future video
Great vid. Thanks for sharing. Question: what's the HIGHEST your water temp gets to in the aeroponic hybrid set up? I've heard anything over 64°F is bad, but I've heard others say they've had no problems with water temps up as high as 90°F.
Thanks for your time.
Thurin Hagrem for best results the temp should be below 68f. It can be challenging because of ambient temps. But yes, it’s not like everything is just going to die if it’s gets warmer. But problems can start happening.
Growing Answers copy that. Thanks man. Great channel too btw. 👌
identitygone 68 to 74 is ideal temp .
Above 74 your risking pythium root rot. Below 68 your shocking the plant. Lower temp holds more dissolved o2
Great informative videos, just subbed.
I have a question similar to some of the other comments for this video.
I built a 5 gallon bucket cloner & opted for a pump & misters instead of air pump & stone. After using it for a few months with good results (nubs in a week, transplantable to soil in 2 weeks using plain tap water only). Now I'm wondering if I'd get better results faster if I got more air into the bucket, since it's pretty much a sealed system??
Or am I worrying about nothing?
Or would adding just some rooting solution additive be better?
Mark B it’s not really a sealed system if ur using net pots. As long as there is some way for air to exchange, it’s not going to suffocate.
Growing Answers
Thanks for taking the time to reply.
I'm not using net pots, I just drilled my bucket lid to fit the neoprene/foam inserts. I can hear air escaping through the insert slits when snapping the lid into place, so it's not airtight but there's no free exchange of air either.
Would you recommend that I add maybe a pipe coming out of it somewhere to let some fresh air in? Or not even bother since I'm getting good results in 2 weeks time?
Thanks again
Mark B there needs to be some air exchange. Crack the lid a little.
Dwc with halo works great as hybred also works nice
please do Airstone vs Aeroponics with CLONING
also with the air stone method you could use a floating piece of foam so as the water level lowers the foam lowers along with it.
I use a RDWC and my power went out for three days!!! I was 5 weeks into veg so no big deal at all. I will actually turn my lights out this run to switch to flower happy accidents!!
Can you do a comparison video on aeroponics using a mist maker ultrasonic atomizer vs dwc with airstone?
Jackson Ransom I will be at some point.
For clarification, you no longer are injecting air into the container? You are just relying on the falling water to push air into the water basin?
I'm trying to decide if i want an external reservoir and a dry root area or having the reservoir inside the root area like you have.
Just wondering your thoughts
No air injection, but roots don’t breath like animals do. As long as the container is not air tight, there plenty of oxygen. And this is really just a proof of concept. When a plant is large, the evap doesn’t really matter I’m either method. It’s sucks up water faster than it evaporates. Small plants however, will benefit more.
@@GrowingAnswers VPD
Just found you and this is pretty intriguing. Gut instinct says that the airstone, with the small bubbles, is going to aerate MUCH more efficiently, so you're just sacrificing aeration for convenience. The fact the airstone is evaporating considerably more water away would seem to bear that out, because there's probably a greater water/air interface with the mass of small bubbles, compared to a few streams of water hitting the surface. I'd also be curious to see if either method causes the water to heat up. ie forcing the air through the airstone or the water through the holes in the pipe requires pressure and a fluid under pressure generates heat. May not be significant but possibly worth checking temperatures since the containers are, presumably, going to be side by side if I understand correctly. Also will both aeration methods be using identical pumps? You should maybe check the power draw of each as well, if you can.
I wish I had the room for this sort of thing. All my hydroponic space is currently turned over to raising seedlings.
Anton Gully the water pump uses less watts than the large air pump I have. But that’s just my situation. The power draw is so small it doesn’t matter. And yes, by having a pump submersed it can heat up the water slightly if it’s a larger one. In my case the water temps stayed the same. More bubbles doesn’t mean more oxygen either. Not unless an atomizer is being used. Spraying water through the air creates much more water air contact than bubbles do.
But as he said, won't the airstone improve the Oxygen content of the water for submerged roots?
gibbetify if the bubbles become trapped within the roots, yes. Otherwise the o2 diffusion comes from surface agitation and not bubbles. If anything, a recirculating sprayer system has much better contact with air than an airstone can create. But I doubt that really translates to much difference in growth potential
why not just do both?
@@GrowingAnswers A bubble is a pocket of air in the water so it has a spherical "surface" which moves through the water. How is there no surface agitation this way? To my sense there is quite a bit of surface agitation with the bubbles. For sure it will evaporate much faster and that's something I didn't realize before.
I like to use the flood and drain system using the big rockwool cube because even if the power stops the Rockwell cube holds a ton of water
Smart my guy very true an
very over looked
I’ve just ordered some’o’ shaped airstones,I’m going to put them in the soil and see if injected air works…..it should 🤷🏻♂️
Hi, really good videos, thanks for making them. Would be interested to see you talk in more detail about how you set each system up. Keep up the good work
It’s just an airstone with a pump obviously for the aeration. The other was just a very small pump from a terrarium waterfall. I attached the tube directly to the pump, crimped the end and melted holes in the tube with a heated nail. The pump was submersed in the same container. No external reservoir
@@GrowingAnswers - thanks for the explanation !
When the system fail, but falls back to a Kratky system, is a good system ;)
Great video however I think that the water should 100% be changed at least every 2 weeks re nute every time please test this a d see if makes a difference would be a great video
Right and with the airstone methode nitrogen would be pulled out really fast since it is a gas.
Yields and yield per watt are more important for most people
Depending on VPD and humidity targets, you want some evaporation.
Can you leave the pump on 24hrs with hybrid system or would the plant die
Aus Grows doesn’t matter.
@@GrowingAnswers thank you mate I appreciate that alot I just built my system today using your method cheers and have a good day
Air pumps are not needed. Use inline or submersible pumps run resivior to feed water rings 24/7 to buckets head pressure will keep it all fairly level.
Hi the problem i have with aeroponics is that the misters block up and you spend many hours cleaning or replacing them... Your thoughts, compared to the DWC system.. Yes adding a cup of water over a few days is not that hard to do ....
Thanks
Kim Rauch I’m not really talking about using misters though. Simply creating some holes in tubing to creates some water fall effect is plenty if doing it hybrid style. Yes the problems with aeroponics is cloggs and even roots finding a way into the pump. However there are pros and cons to virtually all methods.
If you run aeroponics you`ll discover the low water/nutrient usage allows you to run it drain to waste. Nozzle clogging isnt an issue when pristine nutrient only run through the system once. Drain to waste provides numerous benefits you wont get from a recirculating reservoir ;)
Atom izer so are you talking about a drip system or misters?
Aeroponics, namely high pressure or air atomised. Drip is hydroponic ;)
1:35 Bubbles are literally a surface agitation
I use 2x4 in. air stones with a 300 Amp battery system and 2000 watts of solar, plants grow much faster and easier than soil...
What's the wattage light?
I believe the benefits of an air stone outweigh the cons.
I use stones. I've noticed that with the extra new water coming in I've not had to really change my water that often. This is my 1st grow though. If you got 2 mins here my video of my 1st 30 days ruclips.net/video/0ZeUb-nn1tg/видео.html&feature=share any feedback would be greatly appreciated!
fill and drain does not have to be a 100% drain, you can adjust the height of the bottom of the 'bell' so you siphon wont drain below that point. you then have roots in water 100% of the time and roots directly exposed to air aka 'oxygen' much of the time. also your aeroponics looked like you just had a hole pricked in the pipe and not a misting nozzle. so how is that aeroponic?
Neko Mancer it’s just an experiment for proof of concept.
The best grow is a combination of both bro
lol air pumps create heat thus the need for enzymes which your plants only need due to "ROOT ROT" dont get root rot is the best way.
I wish i was smart like you.
could not imagine the thumb down on these videos. haters!
WATER PUMP WILL MAKE WATER MUCH TO HOT
Put aside the problem and i have cute guys talkin to me with gazing eyes....you can plant your seed anywhere
3 cups over TWO weeks? BFD...😏
I think you need some potassium in your diet. Like, eat a banana a day.
Research Studio I do
No it kinda didn’t help
I wanted to like the vid, but its at 420 likes. I can't do it.
Again, this is not Aeroponics
rarely lucid it sorta is. Maybe not with misters, but same concept. I think I mentioned it’s more of a hybrid. And for the sake of the experiment, it doesn’t really matter what the proper term is.
@@GrowingAnswers wrong .. so wrong... aeroponics refers to growing a plant in an environment in which the roots grow almost solely in air which in turn allows certain characteristics to show themselves in the plant such as hyper fast growth.. 3-5 times faster then soil .. hydroponic growth is only at 2-3 times faster then soil..research actual aeroponics .. what you made was a deep water culture with a sprinkler.. a shitty sprinkler at that... consider this.. a high school footballer calls himself an Olympian.. would you agree that he's kind of an olympian? he's young and runs on a field... No he is not and your system is not aeroponic .. let me help a little with this.. look up micron size of droplets required to absorb aeroponicly .. it certainly cant be build with a nail and propane torch.
@@GrowingAnswers
If the root structure is the same as hydro, its hydro ;) Folks that spray water at roots assume its aeroponic but then you`d have to say dunking a plant in a bucket of nutes every so often is also aeroponic, when it is, in fact, flood and drain without any medium ;).Sprayed roots get wet and are allowed to dry, much like F&D. An aeroponic system should provide a constant mist which the roots are suspended in. Imagine a theoretically perfect soil which maintains optimal moisture, nutrient and air balance at all times, then imagine it without the soil ;) Aeroponic roots, structure wise, have a lot more more in common with soil roots than with hydro roots.
@@rarelylucid4488 are you deff mate it's a hybrid aeroponic system its dwc with aeroponics without the mist
Kinda defeats the purpose of aeorponic when you're "submerging" the roots in water, have fun with the 2.5x growth on the setup you have vs the 3.5x on a real aeroponic method
Lol....you're wasting your time worrying about water evaporation completely blind to the fact that once you have plants in there, and assuming they are healthy and in a proper environment, the plants will uptake the water/nutrients before any meaningful evaporation has a chance to occur. This is common sense to anyone who has ever grown DWC. You have to top off water daily, not due to evaporation, but due to plant uptake to continue their rapid growth. How do you know that evaporation didnt happen quicker in the air stone bucket because that bucket's lid has larger air gaps? Are we to assume those cheap plastic totes have tight tolerances in production?
I have better advice than any of these other comments. No one should be taking advice from someone that can't even bother to put together a proper aeroponic system.
Depends what your definition of a proper aeroponic system is, most folks that think they have a proper aeroponic system dont.
