I'm very interested in growing tomato in solution of nutrients (without any material like soil, just water and minerals), and so to do this the quantity of nutrients needed per day must be known. Well, do you know where i can get such information? I'd be very thankful, if you send a letter to me. (id_est@pochtamt.ru)

Cliff Thanks for the suggestion of RV equipment for use in the greenhouse. At work we call this thinking out of the box and I now see I was so focused on my heat problem I was not thinking out of the box. I did visit a local RV repair facility, picked up an awning crank and works from an accident damaged motor home and presto I have a very very cheap mechanism to open and close a top vent. I also installed two whirley birds to suck the heat anytime a breeze starts. All this and no power is needed. Temperature dropped 15 degrees in less than an hour and yesterday it maintained a comfortable temperature all day. Thanks again

Ron, i have a couple of questions. First of all, I was wondering if it is possible to use an irrigation system for hydroponics. In other words my idea is to hook up a fertilizer mixer/dispenser to the water outlet and let the mixture flood the 9 plant garden setup. I plan on attaching a timer so that everything is controlled. When draining the system is it necessary to recycle the mixture or would discarding it cost too much money?

That is the way most commercial growing systems work. Bags full of perlite with holes in the bottom sit on the ground and drains out the bottom onto the ground. Disney World uses a scale hooked to a computer to weigh  how much water the first bag in the row gets then it knows how much to water the rest of the row should get. That way they have very little drain waste.

The Hydro Gardens verticle bag system is a Flood to waste system. Decreases diease transfer from one plant to the other and assures a uniform fertilizer mix with each watering. Isn`t really that expensive with the right fertilizer but can be messy if you don`t have somewhere for fertilized water to run off too. I beilieve it`s www.Hydro-Gardens.com

passive hydroponics is the easiest. you fill a bucket with nute juice and set a plant in a smaller container with a growing medium (pebbles or sand...) then set the plant into the juice. the simplest active hydroponics uses bubblers- same design but add a bubbler to the bottom of the nute juice. thants my 2 cents... ~Ryan

recently i came up with a solution to leaky 2l bottle caps. every time i tried to get a regular 2l cap to seal to the pvc pipe using pvc glue, epoxy or silicone i always ended up with leaks. if not right away then after the bottles have been removed/tightened a couple of times. the 2l cap is a good fit in the thinwall pvc like ron says, but it's not really that tight of a fit, and the ribbing on the outside of the cap compounds the sealing problem..

i discovered that platypus flexible water bottle caps, have the same thread as a 2l bottle, are slightly larger than standard 2l caps, and are perfectly smooth on the outside. they fit inside the thinwall pvc so well that they don't leak at all with no sealer whatsoever (!)

the only downside is their cost. rei sells the caps for $1 each, for me the extra $11 was well worth the price of a leakproof system.

the plants are put into 16 oz solo cups with holes burned into the sides with a hot nail. then what i do is fill the cup 1/2 way with pea gravel, set the bare root plant (wash the roots with a hose) then carefully fill to the top with rocks then set it down into the upturned 2L bottle that has been screwed into the system. have fun. ~Ryan

What is the proper way to clone a plant?

There are several ways to clone a plant.  You can use vermiculite, rock wool starter cubes, or my favorite way now is areoponics.  You cut a branch  about 3 in. long at a 45 degree angle with a clean razor blade.  Dip the clone into Root Tone or some of cloning gel of some sort.  Then stick the clone and to the vermiculite, rock wool starter cube, or in the case with areoponics, grow rocks.  Seven to 10 days later you should see roots popping from the cubes or other medium.  That is the time to transplant into your larger system.

i dont know what you are trying to clone but the way i clone plants uses some dixie cups and some vermiculite. fill the cups with vermiculite and stick in a plant cutting. watter until damp but not WET and keep damp for about a week untill root nodes form then transplant into soil or hydroponic medium. (it helps to keep the vermiculite warm) ~Ryan

Hi,so I read everything By now I should be an expert.Well I am not and have some questions. I live in Iowa and I would like to have my garden outside. Growing some vegeies and Flowers. Any problems with that? I also like to know how many plants it would take to keep a family of three in greens? Beans peas, carrots you name it. Is there a plan what to plant and when? Starting seedlings inside would be possible. I would like to use a flood and drain system but possibly hidden inside an container filling the space between with (what)? lava rocks? Your Help would be very much appreciated Ernst

Ernst I think that would depend on how much of any specific type of vegetables your family likes. Kind of a learning curve. Are you planning on growing all year or just in a traditional growing season? I noticed you live in Iowa. You will definitly need a greenhouse if you plan anything for winter. I built an inexpensive on for about $150-$175. http://www.sherrysgreenhouse.com/TomUhll.html Cliff

I seen earlier that you recommended that if you can only afford one light, go with HPS. I have heard that during vegetative stages, the HPS does not have a great deal of blue spectrum. -and i have seen elsewhere that MH are best to use during vegetative and they do good in flowering. Please let me know so that I know what to begin with myself.<br /> -Burn

Everything you said is true.  You just get more lumens with that the H P S then the M H and they last longer.  So if you're trying to save money that figures out to be the better deal.  You can use a MH then use a HPS conversion bulb when you need it.

The info you give here is excellent and very helpful. I went through all the questions and didn't find any on how often the air should be exhausted in a cabinet. I have three 2' X 2' x 6' cabinets each have two 2" vents on the bottom with PVC 90's to block out the light and 4" vents on the top. I am using a 6" inline duct fan (250 cfm) to pull the air through. Heat is not a problem. The shortest setting timer I can find is for 15 minute intervals. Would 15 minute on, 15 minutes off be enough time to change the air in them and should this be done 24 hours a day or only during the light cycle. Thanks for your help.

If you have 3 cabinets 2x2x6 then that gives you 72 cubic feet of space (24cf for each cabinet). With a 250 cfm fan you would change the air in all 3 cabinets in 3 minutes and 30 seconds. The air probably changes itself by convection if the system is open. To find out, hold a candle at the inlet at the bottom intake and softly blow it out. If the smoke goes into the intake and into the cabinet then you can bet its vented. If it doesn't having it(the fan) come on 4 times a day for 15 min should be fine. Maybe more if your getting condensation inside the cabinet. .....As usual..This is just one guys opinion. Good luck! Cliff

Texas Heat. high 90's today and the greenhouse, an 8'x15' gothic arch fiberglass. Is way hotter, probably around 115. Just started one system inside over the week end but how to bring the heat under control. Short of installing a large swap cooler....fans won't cut it. Also, it is green and cuts down 36% of UV but no affext on the heat......IDEALS??????

I use 70 percent shade cloth here in Florida to grow everything.  But in July and August it is almost impossible to grow anything even with shade cloth.  So that's when everybody shuts down and cleans their greenhouse and gets ready for the fall planting.

We can buy both Black and green. second question is that I am planning to plant a variety of veggies and herbs, namely Tomatoes, Peppers, Spinach, lettuce, Chinese cabbage , and some beans.

Dear Ron, I recently built the 11 plant garden & had it operational a week ago. Yesterday there was a heavy downpour diluting my nutrient solution w/ the rain water passing through each of the 2L bottles back to the storage tank. The question is: is there a planter designed to overcome this problem & how will I determine how to adjust the proper concentration of my solution after being diluted by the rain? Thank you if you have something to share on this. Joe Holden

Without a TDS meter all you can do is dump your solution and start refilling gallon at a time.
