I made a small system in the house using a old 10 fish tank. Needs some fine tuning like a bigger light and better filler in my net cups but I will have some small lettuce and turnip 7-top to add to Christmas dinners salad. Not bad for my first try just to see if it works and any fresh lettuce in Dec in MN is a joy. Thanks for all the info.
I'm so excited to try the Kratky method, show my friends and family, and get them to watch your videos. With so much crap that's going on around the world, it's great to see someone in a honest grass roots way, helping incubate agricultural ideas that will ultimately help people everywhere. Thank you again Bobby!
I've been starting my seed in 1.5 inch rockwool cubes. Once the seedlings are big enough, after 2 1/2 to 3 weeks, I put them in 2 inch net pots and place them in the Styrofoam. They usually begin growing roots into the water within the first couple of days.
I have to say watching these videos has inspired me to give hydroponics a try again. I have built an ebb and flow system and a bubbler system. I had zero luck with those and it bummed me out. Now I took my bubbler system and tried the Kratky method and after 5 days the roots on my store bought Swiss Chard have amazed me. Thanks again for your info and I look forward to your next video.
Hey Brock... I'm using the same fertilizer that I use for tomatoes, just a reduced amount. I use well water, ph is neutral. I add my fertilizer, set it, and forget it. I don't check ph or ppm during the growth process. I am nothing but a spectator, just watching the plants grow. It doesn't get any easier. :)
I moved the 4 x 8 box to the smaller greenhouse, and set it back up. The only thing left growing was the one cabbage plant, so I transferred it and kept it going. It's a very nice looking cabbage now, about ready to cut. Oughta make some real nice slaw.
I saw the article on the cucumber in a trash can a long time ago. I didn't do hydro at the time, so I left it alone. Earlier this year, this was mentioned on the Bayou Forum. And one of the guys did the floating raft, but with not so good results. The more I read, the more sense it made. So after the rail system worked out so well, I decided to try it. Needless to say, I like it ! For now, I'll stick with leafy plants. But after it warms up, I may try some cukes or squash.
Thanks, this video put me over the top!!! I got my seed, nutrients and hardware to do this with now. Can't wait! Thanks for bringing up the fact that you don't need a lot of space to do this and of course that "Anybody can do this"!!!
I like what I see and I have to switch to the fertilizer that you use. I tried it and my set up stunk really bad and had to throw it out. Got my building permit for my greenhouse and I have been working on it. It is going to be 21 feet wide and 48 feet long and 8 foot side walls 12 feet high.Thanks to you that I am going to build it. I see what you have done and want to to do the same thing. Not getting any younger I will be 68 years old next month. Thanks for all the great videos.
Right now, I'm using rockwool cubes for my hydro plants. But I have started seed in sterile mix, washed the roots off, and then put them into the hydro setups. Washing the roots off will set the plants back a bit, and they'll wilt some kinda bad. But if they make it thru the first few days, you should be ok.
I like to use rockwool cubes for seed starting. As soon as I see a sprout, I get them under some lights to keep them from getting leggy. To keep from doing a lot of mixing, I'd use the Hobby Formula from Hydro-Gardens. All you have to add is a small amount of Epsom salt, something most people have around the house.
That's good to hear Larry. I think it's a good way to get into gardening, period. Once people see what can be done. it might get them interested enough to go out and plant a big garden. Especially kids who've never had any gardening experiences. It's a start. ;)
I left a couple of plants in the rail system awhile back. They did start to regrow. Kinda like a cabbage after you remove the head. Small shoots coming out the side. I didn't let them stay, so I'm not sure how much they would have grown. Thx bro, Merry Christmas to you too !
For being so easy, I really like this. For speed of growth, I think the rails are faster. My plan is to do a side by side test next month. I'd like to see what happens with everything given an equal chance.
Yes, it can be doing in all kinds of containers. Outside, you need to factor in the wind and rain, but it can be done. If you google " BA Kratky", you can get some ideas from his writings. For things maturing in 30-45 days, you shouldn't have to check the water as long as the reservoir was properly sized. I use water soluble fertilizers, since they are cheaper than buying the liquid stuff.
With typical water soluble fertilizer, there is no smell. And it's always a good idea to save buckets and containers. You never know when they might come in handy. Thanks.
Oops : I was over thinking hydroponics go in the middle of winter I plan to grow some greens. Off to find some tubs. Tanks a lot for all of your hard work. Happy New year!
I don't know very much about supplemental lighting. But I've seen a lot of people have success with regular shop lights, the 4 foot fluorescents that you can buy most anywhere. That's what I use for my seedlings, and it works pretty good. In addition to lighting, I'd add some reflective mylar or other type of material to maximize light reflection. Thanks.
I agree. I think the rail setup is faster. I'll do a side by side test sometime next month. I've seen the DWC containers, but haven't done anything with them. Kinda like the Earthboxes, they seem to do well. Thanks, and Happy New Year !
I wanted to thank you for reminding me of the Kratky method of hydroponics. The off grid no electricity method of growing is very attractive as is the shear economics of using one gallon containers compared to soil growing. Here in the Mojave we would be using a lot more water for the same amount of lettuce.
In the first run, I had about 8 gallons left out of 40 that I started with. I pour the leftovers around some plants. The resevoir is completely drained, wiped clean and refilled with new nutrients. Totes are from WMT. Yes, I plan to do something outside. Whew... Merry Christmas to you too Santa !
It's much better than store bought. Growing in the ground does present some problems with insects, but you can get aphids either way. So there is always something to deal with. Doing hydro does keep it fairly clean though.
Thanks mhpgargener! Jus showed this video to the wife and said we are gonna do this. Have given up on soil. Just too many problems.After this latest rain looks like will have to replant again(4th time) You have given us hope we can do this
The water temps will vary, depending on daytime temps. But with a large reservoir, the changes are much slower than with a small container. I just checked the raft setup, it's showing about 60 degrees. That's fine for lettuce and leafy vegetables.
Fav method of growing...hmmm. That's a tough one, cuz I like them all. For simplicity, ease, and production.. I really like the hydro stuff. But for some awesome eating and beautiful plants, I like the gardens and raised beds too. I just like growing vegetables...period. :)
It's very simple. 4 x 8 sheet of plywood/OSB. with 2x6 framing to fit. so the end boards are 48", and the long sides are 93". All put together with deck screws. If you put it up on blocks like I did, make sure you have supports down the middle. If not, the weight of the water will cause it to sag and likely lead to problems.
I have watched all your videos a number of times, and that's because i cant believe how easy you make them to understand. Feels like i am missing something its that simple. Now i don't know if you have been asked this question on the radio show or not but do you have a favorite method of growing and which method do you prefer if its not your favorite method? Thank You. And keep the videos coming they are Great and Exciting!
Hey Lisa, I'm not sure what the limitations are. Mr. Kratky talked about doing lettuce, tomatoes, and cucumbers. I have a couple of nice cabbages growing, doing very well. I think the issue will be determining the proper nutrients for each type of vegetable. I do have plans for a lot more experimenting over the next few months, so we'll see what I can come up with. ;)
Thanks. I'm using something called Masterblend 4-18-38, but you could probably do it with something like Miracle Grow. I'll do a test next month to see how it works out.
I've seen smaller heads being to grow back, but I don't think it's worth letting them go on. To me, it makes more sense to get things cleaned up and start over with new plants. However, if you wanted continuous production, you could grow leaf lettuce instead.
It took me awhile to understand the relationship between roots and water. I thought a plant would drown. Now I see otherwise. I use Masterblend, but Miracle Grow tomato formula would probably work. Or any of the organic fertilizers available from a hydro store. Thanks, Happy New Year !
We are missing you on you tube! We just found your YT video's a few weeks ago , and really enjoy your teaching. We are thinking about trying some lettuce and broccoli in our greenhouse. What variety , (if any) do you think would grow in the greenhouse. This year we want get to raise them from seeds, we'll have to buy plants. My husband has been growing veggies hydroponic in his greenhouse for years and they have made a lot. Thank you for you time, and please get back on here, we love to watch you.
There are lots of organic nutrients on the market. I haven't used any of them in a hydro setup, so I can make any recommendations. As for comparing Kratky to AP, it's like comparing apples to oranges...totally different methods. But both are very effective.
Yes, but you'll need to modify the reservoir to account for the additional water usage. The small pots are called "net pots". They are available at most hydroponic stores.
I know you posted this a year ago but maybe you will see it. I teach science and I use 4 gallon buckets from Home Depot to grow 2 heads of lettuce/bucket. My 7th grade students write an actual research paper comparing fertilizers using the scientific method. Six 4 gallon buckets and three 4 ft dual flourescent hanging light fixtures inside of a 1 inch pvc pipe rack. I use 6 buckets for a total of 12 heads of lettuce (3 buckets of one type of fertilizer and 3 buckets of another type). When the research is over, we give the lettuce to the cafeteria. My students built a system that will allow me to rotate 12 heads of lettuce/week total to give to the cafeteria all year long. If you get this, look me up on FB and I can send you the pics of what my students built and how it works. David Holcomb, Oklahoma City
Man oh Man Bobby!! You really make it convincing that even me and my BLUE thumbs can do that! Fresh Christmas lettuce sounds like a nice treat! God bless you and your family, thanks for all your videos and wisdom. Merry Christmas and Happy New Year! - Nick
This a butter head, meant to be cut all at once. But I reckon you could treat it like a leaf lettuce. As long as it doesn't bolt, it might keep on going.
LOL...Blue thumbs ! With this cold front blowing thru, I bet a lot of folks are having blue thumbs outside. This wind is just ridiculous. Merry Christmas to you too Nick !
I have a long to-do list too. So many things that I want to do or try. My plan is to build a couple more of these 4x8 setups and step up the production. I'm gonna turn the folks into vegetarians ! Thanks Tim, Merry Christmas to you and your family as well. :)
Another great video from the master....Seems pretty easy to set up and all.....Really amazing what you have accomplished in a couple of years....I wish I had your drive to get things done....I have a long list of to-do's and slowly get things done....of course you continue to help me add things to that list....LOL.....God bless you and your family....Merry Christmas and Happy New Year.....:-)

From what Mr. Kratky said, you could grow a lot of things. But you have to make sure that the reservoir is sized properly to provide enough water for the entire growth process. Otherwise you have to begin adding water and adjusting nutrients, thereby defeating the original purpose. Google " BA Kratky " ... he has some great explanations.
From what I've heard, there is a lot of variation from one country to another in regard to what people have access too. I would look online with some local stores and see what they had available.
Awesome Bobby my fertilizer cam to day so I'm going to start to mix my own. I got 25 lbs fert and 25 lbs cal nitrate. I says it has magnesium in the fert but I can always add some Epson salts. so have some studying to do. thanks for the reply Bobby it's much appreciated. Merry Christmas Brother!
I haven't tried basil. But from watching other videos, it seems to be very easy to grow. No idea how fast it would grow, but my guess is it would grow like a weed...fast. ;)

How to Fertilizer ??
Can you teach me. please .details
I moved the 4 x 8 box to the smaller greenhouse, and set it back up. The only thing left growing was the one cabbage plant, so I transferred it and kept it going. It's a very nice looking cabbage now, about ready to cut. Oughta make some real nice slaw.
Yes, always. For this type of setup, I start seeds in rockwool cubes, the 1.5 inch size. They fit nicely into a 2 inch net cup.
It is amazing to see people with great ideas to grow on their own and help others to start growing their foods

This works. I tried it on my channel. Grew huge hydro lettuce using the Kratky method. Thanks MHP gardener. Keep up the good work
The water situation is critical in many parts of the world. With this method of growing, the water usage is very efficient.
Thanks, this video put me over the top!!! I got my seed, nutrients and hardware to do this with now. Can't wait! Thanks for bringing up the fact that you don't need a lot of space to do this and of course that "Anybody can do this"!!!
Such an important video, share this everywhere.

It's very simple, and the results have been great.
The tubs look like a great little system for people with a small space. Thanks for sharing Bobby :)

i love him and the way he shares his food with others we need more of this ..wonderful...
Yep, and I've heard that you don't need to wrap the green plastic bottles. It would make a neat experiment comparing wrapped and unwrapped.
For being so easy, I really like this. For speed of growth, I think the rails are faster. My plan is to do a side by side test next month. I'd like to see what happens with everything given an equal chance.
Hey Mike, I don't even look at the ppm. I just mix the nutrients as recommended and let it go. It's a very simple process.
Yes, it can be doing in all kinds of containers. Outside, you need to factor in the wind and rain, but it can be done. If you google " BA Kratky", you can get some ideas from his writings. For things maturing in 30-45 days, you shouldn't have to check the water as long as the reservoir was properly sized.

I'm glad to see these simple set up's. This will work in my place. Thanks keep them coming.

The foam isulation is available in the building supply section of stores like Lowes, HD, etc. Thanks, and Happy New Year.
Bobby, you are just amazing. I am thinking me and Mr Modoc are gonna be in a little competition on setting up our sun rooms.
Thanks for the inspiration MHP. I have a 6-slot tote going right now with some tiny thumb lettuces started.
In the first run, I had about 8 gallons left out of 40 that I started with. I pour the leftovers around some plants. The resevoir is completely drained, wiped clean and refilled with new nutrients. Totes are from WMT. Yes, I plan to do something outside. Whew... Merry Christmas to you too Santa !
For sure, this really is easy. Let me know what's on your mind, I'll see what I can do.
It's much better than store bought. Growing in the ground does present some problems with insects, but you can get aphids either way. So there is always something to deal with. Doing hydro does keep it fairly clean though.
Thanks. Try it, I think you'll like the results.
That's great Kevin. Chard is a fairly aggressive plant, and does well in the Kratky setup. I'm glad to hear you're back in the game. :)
I don't go by any PPM measurements. I add the fertilizer according to the manufacturers specs, just keeping it simple. It has worked out great.
Thanks mhpgargener!
Jus showed this video to the wife and said we are gonna do this.
Have given up on soil. Just too many problems.After this latest rain looks like will have to replant again(4th time)

It doesn't get much easier. Set it and forget it. I like that concept. :)
I'm doing a side by side test with Miracle Grow right now. It isn't growing as well as the Masterblend that I've been using. But it is growing.
Thanks Lois. I really like the results.
I'm using 1 inch. It works out pretty good for the 2 inch net cups.
Merry Christmas to you too !
Yes.. I showed how to build the boxes several weeks ago.
I have watched all your videos a number of times, and that's because i cant believe how easy you make them to understand. Feels like i am missing something its that simple.

Yes, but you'll need to modify the reservoir to account for the additional water usage. The small pots are called "net pots". They are available at most hydroponic stores.
Thanks. The same thing I use for tomatoes...Masterblend 4-18-38...just at a reduced amount since lettuce doesn't feed the same as tomatoes do.
Awesome ! Those roots are just so cool to see. Nice and clean, just beautiful. ;)
This is great!!! I am creating a lesson plan on hydroponics and will probably use your video. Thanks!

O MAN you are really coming up with some amazing ideas. thank you for sharing
For very dry areas, hydroponics makes a lot of sense. It's hard to water plants when it's just not available.
Nothing less than awesome Bobby - thank you!!!
As always, family comes first. I hope you have a great time with the kids. ;)
It depends on how much you buy. I think it's close to the Miracle Grow Tomato formula price wise. And a little bit goes a long ways.
Thanks bro. Happy New Year to you and the family !
I've been starting the seeds in 1.5 inch rockwool cubes.
Merry Christmas Bobby!
God bless You.
15-30-15 is for increased flower production. If you want to use just one fertilizer, get the MG tomato formula. It's more balanced than the base MG or the Bloom Buster.
This is my thinking in regards to plastic: Plastic is everywhere, there's no getting away from it. From what I can figure, the problems arise when you heat the plastic. Without the heating, it should remain very stable. I would be a lot more concerned about what was being sprayed on the food that we get in the stores. Just my 2 cents of course. ;)
You are doing a great job! I'm very impressed by what you revealed here
I thought hydroponics meant you must have water circulating and algae clogging up the lines and the pump, but your lettuce is superb and I'm hungry now!
From what Mr. Kratky said, you could grow a lot of things. But you have to make sure that the reservoir is sized properly to provide enough water for the entire growth process. Otherwise you have to begin adding water and adjusting nutrients, thereby defeating the original purpose. Google " BA Kratky " ... he has some great explanations.
Yes.... you add the nutrients/fertilizer when the box is filled with water. For fast growing plants, it's a one time deal.
Looking good my friend!
Thanks. I think you could paint the clear ones. But I've never done it, so I'm not sure how well the paint would stick.
Thanks.... Staying tuned.
Eureka! You solved my problem! TY Bobby!
I hear that! Mine is heated (kinda) but this is amazing stuff.
God Bless You and your work.
From what I've heard, there is a lot of variation from one country to another in regard to what people have access too. I would look online with some local stores and see what they had available.
Awesome Bobby my fertilizer cam to day so I'm going to start to mix my own. I got 25 lbs fert and 25 lbs cal nitrate. I says it has magnesium in the fert but I can always add some Epson salts. so have some studying to do. thanks for the reply Bobby it's much appreciated. Merry Christmas Brother!
Look for this video... "Hydroponic Fertilizer : What I Use & How to Mix It" ... I explained it all. It's a cool way to grow.
Great video loved it so much sent it to all my friends. Merry Christmas and God Bless
Man,,,, your lettuce is fantastic well done,,,,, I'm going to try your way,,,, thank you so very much
I haven't tried basil. But from watching other videos, it seems to be very easy to grow. No idea how fast it would grow, but my guess is it would grow like a weed...fast. ;)
Wow amazing will have to watch the other vid on this system
New too hydroponics... starting germination tonight.. exited
Very impressive as always Bobby..
Shall pass it on..
:)
