Hello -- I just want to mention that Art Smith from Alabama Hydroponics (http://www.alabamahydroponics.com) is kind enough to host Tomato Challenge 2002. The basic objective is to grow tomatoes hydroponically and you can use any system to achieve that objective. In case you are curious about the rules, please visit his website and learn about them. As a matter of fact, that site should be viewed as an excellent place to get feedback from other tomato growers. I had a lot of fun with Tomato Challenge 2001 last year and met some really cool people on the internet. hydroponically. Hope to see you all at the contest. Happy Growing, Wayne

I went to a store that sells hydroponic items. I asked the clerk if it was difficult to get a 6-10 tomato plant system. He said no but then I told him that I have no CLUE about gardening and I asked him "what percent of people that purchase everything that is needed have success without reading and doing extensive research." He said that the percent rate is between 75% and 80%. He was on the rude side and not to upfront with some of his response. My Question is

Why would the % of success rate not be 99% ?

Assuming 1% purchase everything that is needed and can not follow directions (or something)

What is the optimal Ph for growing tomato plants in a hydro system. Also what light regement is needed to induce flowering in tomato plants?

Around 6.0 pH and tomato flowering is not determined by light cycles like pot. I would use 18 hours of light in a 24 hr period.

I was reading through your previous Q & A pages looking for information on constructing a rainforest cloning chamber. I noticed a question posted on pg. 12 regarding the rainforest system. I've come up with a design that works very well. The Gen. Hydro. Rainforest 36 system uses a pump fit with a venturi fitting (like the ones sold in aquarium shops used for power heads)to mix air and water together. The water is pushed through a small length of pipe and splashes against a curved piece of plastic at the top of the bucket. This distibutes the water in a circular fashion to the six net pots. My system uses a 3 1/2 gal. paint bucket w/ lid, 3" net cups w/ lids, Maxi Jet 600 pump, 1/2" PVC riser tubing, full circle shrub sprayer head, 2 - 3/4" lengths of 3/16" rigid thinwall tubing(aquarium shops carry this), and a length of flexible aquarium airline tubing. A regular venturi fitting that sometimes come with pumps WILL NOT WORK with this design. Venturi injectors will only work when most of the pressure is on one side of the fitting and the presence of a little amount on the opposite side of the fitting will render it pretty much useless. My design gets around this problem by injecting the air before it gets into the pump. Once in the pump, the impeller will chop the air into tiny bubbles. The trick is to take the 2 pieces of 3/16" tubing and epoxy glue them to sides of the intake nozzle of the pump. Place them across from each other and facing so the air is directed into the pump making sure that they don't push up against anything. Drill a hole in the output nozzle ( 1/2 way) just large enough so a small piece of airline tubing can be pushed into it without falling out. Connect one of the plastic tubes on the intake nozzle with the drilled hole with a small piece of airline tubing. The other plastic tube will be fitted with a length of airline tubing long enough to reach the top of the bucket. The outside air will be drawn from this tube. Now you will need to adapt the output nozzle of the pump to fit the 1/2" riser ( cut to fit the bucket). I used a flexble piece of 9/16" O.D. 3/8" I.D. vinyl tubing from the local hardware store. It slides tightly over the nozzle and nicely into the riser tube. Then simply screw the shrub sprayer to the end of the riser. Use an x-acto knife to cut holes in the bucket lid large enough to accomodate the net cups ( total of 6). You will need to cut a notch in the lid for the pump cord and airline hose. I hope this helps someone interested in a cloning chamber.

Ron Have built your aeroponic system and it is great. Is there any reason why plants cant grow to maturity and fruit (cuke roots are over a foot long and have reached the water in the resevoir). Thanks for the great site. Jim in Durham

When I left tomato clones in my system for over 3 weeks they started to look poor so I moved them to the ebb and flow. You will have to tell me if they will grow to maturity.

hello.i have a question for you. I was just wondering how long do you have to have your water going for in a cycle?

You just need to water long enough to wet the roots and medium every 20 minutes. If you have a 15 minute timer then water 15 minutes on 30 minutes off 15 minutes on and so on. If you use a 30 minute timer then water 30 minutes on 30 off and so on.

Hello from Wisconsin,

I used PVC cement for all the PVC fittings on my garden. What kind of adhesive is recommended for the securing the bottle caps to the PVC inserts?

Thanks, Dave

The same. The glue really doesn't stick to the plastic caps but is still tight enough not to leak. Use silicon if you have a leak.

Anyone looking to try out an Organic Hydroponic nutrient should check out the MetaNaturals line of nutrients. I`m trying them out myself - working very well too I might add. Trick thing about this stuff is that you don`t have to adjust ph once it`s in your system and the microbes are working. It takes care of itself. I thought they were pulling my chain on this one, but it does work. If it sounds interesting, they have quite a bit of info on their site. Check it out - http://www.metanaturals.com Mike

Is there any need to use a one gallon size "11 plant" garden, or is the 2 liter size sufficient?

What is the best way to ship it? Disassembled?

Where is an inexpensive place to buy Hydroton?

Peace, Glen

For large plants or long term plants a larger container should be used.
The best way to buy grow rocks is to find the closest grow store and buy them because of shipping weight cost.

To the person who asked how much a 400 watt HID to operate. Its easy - Look on your light bill, they should say how much a KW hour costs - Mine was 8.5 cents. 400 watts = .4 KW (.4 times 8.5 = 3.4 cents hr). (3.4 times 12 hrs = 40.8 cents) For a 30 day month this would come to $12.24 per month. Note, you can purchase a lot of tomatoes for this price. But you would miss the fun!

which is better for indoor growing hid or hps? 

I think you mean Metal Halide. Both MH and HPS are hid's (high intensity discharge).
HPS last longer and cost less per lumen to operate but cost more than a MH. I know MH is best for veg stage and HPS for flowering but if you can only afford one light I would go with HPS.

Hi Ron I have grown Hydroponic Tomatoes going on three years now, I just ran into your web site. Maybe you can help me with a question I have? Would there be a quick way to take Chlorine out of my 75gal. tanks of water before adding my tomato formula. I know I could let it sit for 24 hours and that helps. But I was thinking maybe something quicker. I ask this too hopfully better my formula for the plants. I do have a page to see what I have been doing if you cut and paste http://face-up.tripod.com/caricatures/id12.html Thank you MikeNewsome.com

Ron why do you think some growers suggest a general ph of 6.0. It has been critical for me to keep my ph at 6.5 to 6.8. Also all of the stress over nutrients, I use 5-11-26 and calcium nitrate equal parts @ 1.5 to 2.0 ec to grow everything. My plants produce very heavy and appear very healthy ? Is this the art of sales ? thanks Ed

I go buy what the commercial growing experts say. I figure they would know because they have a lot more to lose if they aren't.
