We are thinking of starting a system to grow tomatoes hydroponically here in Missouri. I dont know much about it yet. I would like to hear from anyone in my area that is doing this. Please respond to both addresses GoldeLock2 and Retread30 Thank you, Mary

Any work been done on the growing of wine grapes hydroponically? Would be very interested in comments and views. excellence@hot.co.za

Me too. Lake County is becoming quite a wine grape grower and I would like to show them a different way to grow them.

Any suggestions on something to use to prop them up.... i need to be able to move them individually so i can clean the tanks?

Brett

I have used a thin bamboo stake stuck in the cup and used a bread tie to hold up the plant. That way you can move the plant and stake.

what the f*ck happens when your pvc is clogged with roots

You lift the plant out of the 2-liter bottle, ( that's why you use the solo cups with holes ) about every week or so and clip off any roots heading down the pipe. If the plants are watered often enough the roots won't have to go looking for water. If they get hopelessly clogged then empty the garden and use liquid plumber to dissolve the roots, then flush with a hose. 
If that don't work, then get the f*ucking hack saw out and start sawing the c*ck s*cking b*tch in pieces and extract the roots and use 1" couplings to glue it back together. Better yet don't glue them encase it happens again.

is hydroponics suitable for the tropics? i'm an indonesian

The largest hydroponic tomato grower moved from Florida to Hawaii because of the weather so I don't see why not. And Carol from Hawaii does OK. http://www.hydroponicsonline.com/carol.htm

Thanks, Ron!!! I read your BB everyday. I think this is the best site with the most information that I have came across, and it has encouraged me to try hydroponics... I also GREATLY enjoy your answers! I am never certain if you are answering with good humor or with a little irritations! I choose the humor, and it usually gets my day off to a wonderful start! Thanks for all of the wonderful information!

I have to admit my humor leans towered the sarcastic side but I think that is good because sarcasms without humor is like aaahhh. like aaahhh well it's like something..

Ron hello, I have 2 questions. 1: when you talk about T.D.S./p.p.m./e.c., or other references to nutrient levels in the water, do you ignore the amount that is already in the fresh water, and add the amount of nutes? say you want a 400 ppm, and your fresh water has 150 (without nutes) do you add the 400to the 150, for a total of 550? being as one doesn't know what is in the water that you are starting with this has confused me. 2: I see you are using and selling a commercial nute, how did your tests with miracle gro, or the generic equivalent with epsom salts and calcium nitrate work out? did you grow tomatoes to completion with it? Thanks for the great site.Montana Mogy

Yes you include the ppm of your water. It is really to small to worry about. 
I just don't seam to have a problem growing anything no matter what kind of nutrient mix I use. Sometimes I use strait water when I get to busy to add solution and my plants still grow like crazy. 
I will be setting up test gardens in the near future, now that the last frost has past, to test different solutions mixes and different mediums.

my question is about root rot ...

ron, can you please describe to me how initial stage root rot looks like ?

i have suspicion that i am experiencing partial root rot bec. my roots are yellowing and is brittle. it seems that the root growth is very limited and preventing some essential nutrients to be delivered to the main plant itself.

thanks

xpac

Root rot won't be brittle they are more like mush and will disintegrate upon touching them.

hello ron,

wonder if you use hydrogen peroxide in your nutrient solution ... some says it has positive effect while some dispute that the value of hydrogen peroxide is very limited since it is a very volatile material ... volatile as in its effect is very short term.

Haven't tried it but did hear about it from. somewhere.

Hydrogen Peroxide is an excellent additive to hydro nutrients. It helps prevent root rot and keeps down unwanted algae growth. It should not be used at more than 3% strength in any solution as it will burn. I disagree that the effects are short lived.

What is a good stable acid to use for PH control. Ive heard that muric acid works. How about sulfuric acid like used in hot tubs.Id like to know your opinion Ron. Thanks23

I use General Hydroponics Up which is phosphoric acid, citric acid, and ammonium bisulfate. And pH Down that is potassium carbonate and potassium hydroxide but I don't know at what proportion or I would mix my own. 
Any chemist out their want to try?

for the question of stable acid for ph control, I buy powdered citric acid(1 pound) from the local drug store($10).mix 1/4 of it with 1 quart water. very efficient for ph down & much more natural than other acids.ps,just my opinion but if an email address was included with questions other members could respond with solutions easing the load on ron.

Re: Viticulture and Hydroponics Ron, Thanks for your comment "Me too". Nudge,nudge wink wink. I understand work has been done in Israel on the growing of table grapes interspersed with cash crops such as tomatoes and cucumbers. There are a number of upsides I have been told. Do you or any of your site Members have any experience or comments with respect to the growing of wine grapes hydroponically. Is it commercially viable?

The only problem I see is that I just have not seen any woody plants like grape, roses, shrubs and just about every other kind of tree except banana trees grown hydroponically and I suspect they are really just big plants.

Hi 23-I am not a chemist but I am sure Ron meant Gen Hydro Down when he described the phosphoric acid solution. I think Ron is keeping late hours again he he. Good Growing Nurse Duckett

How do I keep my hydroponic tomatoes healthy after I plant them?

Feed them the correct nutrients, Keep them at the correct temperature, adjust the pH every day, protect them from predators and play heavy metal music at the highest volume you can turn your stereo to. They like that.

hi,i have a choice to get two light systems im not sure which is the best for growing, the stuff. the choice is between a 400w MH and 400w HPS. THE OTHER CHOICE IS, 2,400w HPS LIGHTS. my grow room is 6' x 5' x 7' also should i spend the extra money for the agro bulbs?. the type of system i was looking at was the diamond lumenarc lll. dose anyone have any experience with these lights. will anyone recommend a lighting system. thank you.

It is better to use both MH and HPS to give your plants the full spectrum of light. If you can afford it then buy the best bulbs you can because they usually last longer and put out more lumens.

On the matter of PH Control, I am a chemist working for a leading manufacturer of nutrients and supplements. I personally manufacture PH control and can tell you the best options are, NITRIC acid in the vegetative cycle and PHOSPHORIC acid in the flowering/fruiting cycle for down control. For up control in both cycles use a Caustic-Potassium Carbonate based formula. I would not recommend sulphuric acid. Remember all acids and caustics are reactive even in very dilute forms and should be handled carefully. Always add acids and caustics to water never the other way round. DO NOT ADD ACIDS AND CAUSTICS TOGETHER. This is potentially dangerous. Hope this helps.

To the person concerned with curing hydro pot. It is VERY important to flush your crop with water for several days before harvest to remove salt and mineral buildup. If you don't it won't burn ever. Hang to dry two to three days depending on local humidity, wait a week to smoke (I know that is the hard part) to allow for a proper cure.
