RON Im trying to grow watermelons and cantaloupe do you think a 3.5 gallon bucket is big enough to hold the roots Im using a homemade aquafarm stile setup and would appreciate any insight you have to offer

Should be plenty. I grew cantaloupe in the 16 ounce cup system a few years back.

Hi Ron, I just purchased a plant called Horses Tail. I then found a link to you for the plant. I know nothing about it and cannot find it in any of my books. What can you tell me about this unusual plant. Ron (that's me too) ronlene@att.net

The herb guy that I bought it from at a flea market here in Central Florida just told me that it was used to cure athletic feet. It grows great in hydro and when I planted some in my yard it is still growing. See!

Ron, I am working on a new system; it is a sub-level hydroponic grow hole for production of tomatoes, basically. My plans are for a 14x70 ft. 6 ft. below ground level to use geo therm temps. after looking at all the systems, your pipe dream is really impressive. Is it possible to get more info from , and about your system ?

what kind of info? everything I know about hydroponics is on this web site. what else do you need to know?

Hi Ron

Just wanted to thank you again. The extra time that you have put into the 11 plant system, allowed me to setup (testing) oh about 10 mins.. With the system basically already built, Cool. I had to use aquarium sealant beaded around 2 threads that's all. But 1 I over screwed, so that's on me. The reason I used sealant instead of PVC glue was I may need to take out for whatever reason.

Great work Mr. Ron

Thank you.

Question?

I would like to make a aeroponics clone starter. I have a plan to make the device(5 gallon pail design) but need to know about the mist system. How fine does the mist have to be? Can it be more of a stream or do I need a true mist? Should I use a combo of the two? What size pump? Considering a Rio 180, big enough? Are the mini sprinklers I see in the catalogs what I need?

Don't know

Question #2

Have a three by three indoor grow area that needs to support three or four tomato plants. Do I need a 400HPS light or is a 250 enough?

400 W, tomato plants love light.

Thanks for the input

Please let me know if I am understanding correctly. Instead of paying large sums of money for those three part nutrient systems I can buy Miracle Grow add Calcium Nitrate and Magnesium Sulfate (Epsom Salt) and get similar results?

That's right. Miracle Grow for Tomatoes to be exact.

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.

I started my plants in small rockwool cubes. I put the cubes in the cups with grow rocks. If I wet the rockwool cubes every half hour or so, am I going to get root/stem rot in the cubes?

I don't think so. I know that would be better than letting them dry out because then they would be toast.

Attn: Eric/Brown tomato Roots

Last year when I first built Rons system, I had the same problem. It's called "Too much ambition". I believe the brown roots are caused by lack of oxygen in the root area. The plain simple truth is that the 2 liter bottle and 16 oz cup are too small for tomato plants. That's why Ron uses gallon grow systems for his operations.

When the roots grow larger, they will start to clog the pipes and starve the plants the furthest from the inlet/outlet fitting on your system. The nutrient will also not drain back to the tank and will maintain a residue that tends to rot the roots.

I suspect that if you want to try to save your plants, you must quickly move them into a larger system. I personally would clip the roots back and inspect all to make sure they aren't long enough to clog the pipes. You may have to do this every other day or so until they can be moved.

I have made the 11 plant system. However I am using it as a flood and drain system; ie, raising and lowering a 5 gal bucket. I am using pea gravel on the bottom few inches, and 3-2-1 pea gravel, perlite, peat moss in the middle, and a little more gravel on the top. I figure the peat will hold water if I can't flood and drain enough. Any suggestions on how often to flood and drain? and how long to let the water sit in the bottles before draining.

Hi. I am very new to hydroponics. I have some basil growing and they don't look as healthy as they should, so I checked the pH and it was around a very low 4. The bottle that contains the pH checking solution recommended that potassium hydroxide be used to raise and phosphoric acid to lower the pH. Do those two particular chemicals have to be used to adjust the pH? Or can other alkaline and acid chemicals be used? I asked a local garden store if they had anything for hydroponics (they didn't). They did have something for fish tanks and outdoor ornamental ponds. Would something like that work?

So far so good with the rockwool cubes (where I started the seedlings) and clay pellets in the cups. One minor catastrophe when the timer I use lost it's programming but I caught that in the nick of time.....

Stay tuned to more hydro drama and see if he has any more problems with his timer.

what kind of pump should i use with the 11 pipe system? do i have to worry about it or will a too strong or weak one not work effectively?

To weak would be a problem. 100 GPH on up would work. If you use a large pump you can use a flow control valve to slow the flow to the garden. To strong a pump will negate the over flow pipe and cause the garden to over flow the cups.

Blake,

You oughta just give your email address then everybody can email you and _know_ you'll see them. ;-) Much better contact plan, eh? Or, you could email out a "secret" web page w/ the plans on it. Change the page title once a week/fortenight/month/etc, just for spy-giggles, and then send the URL encoded ROT-13.

Now, if I could only figure out how many White LEDs would be required to grow tomatoes...

are those high-bright or standard LEDs ? what size ? 3mm ?. It'll probably be easier with 10mm, but i don't believe I have ever seen 10mm high-brights :)

Funny thing is, there is someone out there who would calculate the amount of 3, 5 or 10mm LEDs you'd need.

5mm White LEDs... 5600 mcd @ 20mA, 3.6v -- very nice, and bright.

I found some interesting pages about folks growing under red and green LEDs (mostly NASA or JPL related). Interesting, but pretty useless. I was thinking that the white LEDs might fare better for two reasons... better spectrum, and v. hight brightness. The LEDs the other projects used were on the order of 300 mcd or so, and arranged in large banks.

Forget LEDs I think the future is in Fusion lighting. A new cheaper , more energy-efficient light that uses sulfur particles that are bombarded by microwaves to produce a bright light that resembles sunlight.

HOW DOES THE HYDROPONIC SYSTEM WORK?

The timer turns the pump on. The pump sitting in the nutrient solution reservoir pumps the solution up the hose to the garden to supply the plant roots with food. The plant roots will use as much nutrient as it needs and the rest is returned back to the reservoir for the next feeding. Determined by your timer setting. About every 15 minutes. The overflow pipe keeps the water from rising to high in the cups. This is the ebb and flow or flood and drain hydroponic system.

Hey, Ron! Time for another project! I've had the "Live" page as my browser start page for a month. A MONTH! The last time you had a project was May 1, 2001. I know because I've been staring at it for a month. A MONTH!

Aw, come on. Even if you just point the camera at your mail box or something, give us SOME input. PLEEEESE? Just don't point it at the clock or something. Give us some plants to watch.

Sorry. my live camera broke so I took these pictures with my still camera Click Here.
