Does anyone know if using fluorescent tubes hung two or three inches above growing plants works?

For the first few weeks yes but after that you aren't going to grow much with fluorescents.

Hello, I am in the process of building a 24x72 green house. I will be using hydroponic methods to grow vegetables. I am curious about yields for certain plants. I cannot find any info. I especially want to try peppers, green beans and tomatoes what kind of yield will these give me. I am familiar with what they'll produce in the garden. I have seen so many stat's on what I can expect. Would any be able to lend me some insight on pounds per plant per growing period. Thanks MW

TWO 11 PLANT HYDROPONIC SYSTEMS FOR SALE These were only used for one month and a half inside a store in New York for a window display: I have two pumps, 35-32 oz white bottles 20 oz solo cups, 2-Power Head Pumps, the Grow Rocks cleaned, 2 pH Test Kits, 2 bottles of pH Up & Down, 2- only 1 slightly used 5 lb. Nutrient Solution, 2-24 Hour Timer, and various lengths of PVC with the bases for the bottles attached that can be built into a garden system. I can email you images of this if you want, but I need to sell this ASAP, as I am leaving the country and need money: I would like about $175 for the two systems: the only thing you would need to buy is the tanks, which can be bought at any home depot. Thanks please email me or call 212 343 1038, You can pay me by paypal and I will ship them to you. Thanks

I am growing in an hydroponic system. About a week ago, I noticed small brown spots started appearing on the margins of older leaves. Now it seems to be spreading to the younger ones as well. Can anyone help? TIA

10ft x 4 ft. you can grow in that space, provided there is enough air flow and light. you might not be able to move around much in there though.

Is there a good rule of thumb that I can use to relate the dilution rates of soil fertilers for hydroponic solutions? For example, I've got some Green LIght Super Bloom (12-55-6) that calls for 2 tsp per gal of water. To make a hydro soln, in general, would it be good to use the same dilution rate and just add 1/2 tsp of calcium nitrate and 1/2 tsp of epsom salt?

Thanks

That would be my guess. Watch your plants though and cut back if you notice fertilizer burn.

Yep - I grow vast amounts of cucumbers, i have 2 massive parsley plants, grew eggplants last season, and have grown baby carrots and spring onions in vermiculite. It's no economically viable to grow rice hydroponically, so i haven't bothered trying.

Date: 20 May 2001 Time: 13:10:45 Comments I have started a hydroponic tomato garden. The plants have been in it about 18 days and have really been looking good. I have noticed in the past few days that the better boy's leaves have curled up. The others are doing well though. Also, there is a brownish looking residue in the tubes and some of the roots have this brownish look to them now. The roots used to look white when they first started to grow. Is this some sort of fungus or algae growth? Should I do something about it? If someone could offer some info, I would welcome it.

Thanks, Eric ejordon21@home.com

18 days is to early to worry. Just keep an eye on them longer before you panic.

New reponse:

It has been just over one month now and almost all of my tomato plants are gone. The leaves continued to curl up and they stopped growing. They arent dead yet, but they might as well be. I was using a hydroponic fertilizer and adding one teaspoon per gallon of water as directed. If anyone knows a better fertilizer to use or know what I am doing wrong, I would appreciate the help on it.

Eric ejordon21@home.com

If your pH is to low or to high it won't matter what kind or how much fertilizer you use it won't help.

When is the best time for optimal growth to run co2/ when the lights are on or off or both/ How long should it be run for?

when the lights are on. co2 doesn't work in the dark. 
without a co2 tester it is imposable to tell. You can only guess. For a 10 ft x 10 ft x 8 ft room I would use 1 cubic ft per hour on your flow meter for 15 minutes every hour.

I am thinking about running co2 / I have a 700cu ft room. At what intervals should I should I fire the co2. I was told 6 times a day every 2 hrs for 2 min. Then to leave it for 1 hr before venting with fresh air. Does this seem correct? Also should I run the co2 when the lights are on or off or does it matter? I am having difficulty getting answers to these questions. Thankyou romulus@sympatico.ca

That sounds like as good of a calculation as any.
When the lights are on. co2 doesn't work in the dark.

i was wondering about using the 4 by 4 rockwool cubes in the system you have posted. and what changes in the times of watering would you recommend? im new too it all im going too make a two station set up first too experiments. i have been growing peppers in soil for awhile and i do good but im curios on the indoor aspect of it for the winter time growing. ponics would be less of a mess . i have been reading on this for about 2 years .i need any help i can get on the subject. i love your site it is a force behind my "bug".

Water less with rockwool than with rocks because it holds water longer. Maybe every hour.

I found at Lowes A thing called -Weed Block- it is a black plastic roll of screen and the holes are so small they wont let roots grow threw it, but water and Air flow ok ,I was thinking Of using it in the 11 Plant garden - Its strong But It will rip- I am thinking of just stuffing some in the soda bottles and put the lava rocks in it - make a little bag of lava rocks in the soda bottles

The weed block is used by land scapers to keep weed out of flower gardens

Do you think this will be ok or do you think I should still use some type of cup or mesh pot

-will-

Yes that will work. I also use old nylon shade cloth.

Hi Ron , Ready to start a 11 pot system but i am still confused on the theory of the ebb/flow system. Is he pump supposed to just fill the system in this 15 min. on cycle ,or is it supposed to quickly fill up and have a flow of the nutrient solution over the roots, and if so can there be to high of a volumetric flow rate which will damage roots?

Yes the pump fills the garden for 15 minutes until it turns off and drains and no the roots do not suffer volumetric flow rate, what ever volumetric flow rate is. Like I need something else to worry about.

hello, i have a little problem well i have your 11 plant system in a tank with co2 and a vent system . right now i am using florescent lights until i have enough for a hid light but i have 3 plants in there and there about 3" high and the ends of the leaves are drying out and curling up. what can that be from? i dont know how much nutreint i am suppose to add so i guessed it i have dyna grow for about 35 gallons of water. could it be the air? help

I have never grown in a small chamber. You can give plants to much co2.

It would be better to stop the algae from growing at all. Where is the algae growing ?

Please! Algae is you friend. Without algae you have a problem with hydroponics. Have you ever seen a healthy stream in the wilderness without algae. Algae means that their is nutrients in the water that your plants need. It only becomes a problem when it gets so bad that it covers the top of your medium and prevents oxygen from being suck into the medium when the water drains from the cups.

Hi Ron, Hi all, Iv'e been lurking recently and now have a ligit question. I am growing tomatoes in a 6 plant 2 litre bottle system, I transplanted 4 weeks ago, they have tomatoes about the size of a 1/2 dollar. It is now time to change the solution, I have had the solution set up for growing phase, should I now change the nutrient to blooming phase or keep the grow phase mix? I am using general hydroponics solutions. Thanks to Ron and this site, this is my 2nd growing season and it only gets better! Tony in Va.

Because greenhouse tomatoes are indeterminate, which means they grow and produce fruits continually, all you can do is compromise and change your solution to bloom about half way threw to completion which is about two months for tomatoes that take about four months total to finish.

I grow strawberries, or should I say, the strawberries grow and I watch them. I use Vertigro pots stacked 10-high filled with vermiculite/perlite mixture. I water them once a week with a standard nutrient solution. Vertigro have a website at http://www.vertigro.com if you want to see what I am talking about.

Hi ron i need your help or any input you can spare for me. i have a 4 foot by 4 foot by 4 foot tank with co2 and a vent/ac system and right now im using 2 floresents and the inside of the tank, the tank is all wight, i had a lot of alge growth and the tips of my leaves were curling up and turning brown on the older sets of leaves so i rinsed out the system and leached it because i read that it could of been too much nutrient so i added fresh water and rinsed the roots for about 5 mins and added some grow food and now the brown curled up leaves turned into wight curled up leaves, can u tell me if i don't have enough nutrient or is my ph messed up or is it just the color of the already edad leave any idea at all???. thanx love ur site

I have never grown in such a small area so I have no idea what you are going threw. My guess would be you are off on everything. Start over and if that don't work them give up you are no grower.
