Great site, thanks! But why do so many systems have little cups inside of the 2-liters? I didn't see anything about that in your plans. Thanks!

To hold the medium so it won't go down the pipes and to make the plants removable  or just to be able to lift the plant up to see what the roots are doing.

We built your 11 plant hydroponic garden, but how do we put the plants in it? We saw the picture with a plastic cup in the bottle, but how does that work? Lathrop Adv. Tech. Class

Wash the dirt off the plant roots. 
Put a few rocks in the bottom of the solo cup. 
Place the plant in the cup and fill it up with rocks.

 About the little cups again: So plants go in the little cups and cups go in the 2-liter? And the roots are in the cup, or do they extend out? How big should the holes be? Thanks!

It's OK for the roots to grow outside of the solo cup but don't let the roots go down the pipes and plug up your garden. If you water the plants often enough the roots don't need to go looking for water. The holes in the solo cup should be small enough to keep the medium from going through.

does lettuce grow ok in Grow-Rocks? I want to grow lettuce and chives, and like the design of the 11 plant system - will it work alright?

That's exactly the size and type of plants that grow very well in the 11 plant garden. Tomato plants are to large.

how come all the big gardens seem to not have the ebb and flow but have the drip. it seems that way in the pictures i checked out. is there a reason for this? steve

Because the size of the reservoir and pump needed for a large commercial gardens. The more volume of water needed to fill a system the lager a pump needed to do the job.
I use 50 gallon drums for 100 tomato plants and they use every bit of it every 24 hours. That means mixing fertilizer everyday for each 100 plants. I will be buying a 200 gallon tank soon for my spring planting.

Do you think clearing solutions are needed before harvest? I have heard that some people use just plain water. I personally believe that this would not be the best solution because It seems that the plant would suffer due to lack of nutrition.

You only need to flush if you have a nutrient solution problem.

The more expensive hydroponic solutions come in bottles and can be ordered online from a number of links on this web site. Or if you are on a budget and can wait a week I will be selling 5 lb. boxes of hydroponic nutrient solution cheap.

how big does a unit have to be to make money growing say tomatoes, beans, herbs

A good indicator for tomatoes is 25 lbs. for every square ft. of greenhouse space. And all you have to do is see what tomatoes are going for at your supermarket to see how profitable it can be.

Another for Tomatoes is they require from 3.85 to 4.75 square feet of greenhouse area per plant. Therefore, the plant population in a 31' x 132 greenhouse will range from 1,060 plants to 834 plants. Production is normally calculated in pounds per square feet of greenhouse area. It can range from 5.5 pounds per square foot to 7.25 psf per year with currently available varieties.

I am new to hydroponics, and i have a few plants in soil and a few in the 11 plant garden. I have taken clones from the plants in soil, and they are doing fine in vermiculite and plain water. I also have taken a few clones from my hydro-plants, and they are not doing fine in only vermiculite and water. Do I need to use a mild nutrient solution for theses clones? Is vermiculite o.k. or should the clones be put in the 11 plant garden? and watered 3 times per hour? any info will help out alot, thanks

Yes you should use 1/4 strength solution for clones.

has anyone ever grown using co2 from a source of baking soda and vinegar is there any other methods to create co2 for a small sealed grow area. thank you

co2 Enrichment

I know this was asked of a small growing area, but if you have a greenhouse you can compost inside it to produce co2, or bring compost inside and put it on the floor of the grow area. A bale of hay will give off co2 also if you get it wet. It will also incinerate from the inside if you don't watch it. I have a compost bed to the right as I go in my GH door, I also have a 2 can bioreactor inside. http://www.cfe.cornell.edu/compost/garbagecans.html

The co2 levels in my GH are sky high. the vent pipe also gives off heat for these cold georgia nights. Just sayin... Tom

For co2 enrichment methods go to

http://www.hydrofarm.com/content/articles/co2.html

So I go here and it says: When organic matter decomposes due to bacterial action, carbon dioxide is generated. Plants grow lush and vigorously on a tropical jungle floor as a result of this natural decay of dead plant and animal matter. This can increase the available CO2 content from the normal 300 PPM amount to over 1,000 parts per million. This can also be done indoors, for little cost, but is odorous and unsanitary. For these and other reasons, it is not highly recommended. The sterile conditions of a well-set-up hydroponic grow room or greenhouse could be disrupted and adverse bacteria, bugs and disease induced with detrimental effects on your plants.

I have to say that composting does not stink if its done right. Also the bacteria that get introduced to the greenhouse are the helpful types that destroy harmful critters. I would say that this company wants to sell you high priced co2 generators that could be replaced by scraps from your kitchen and 2 plastic trashcans. Tom

Does the price for the parts you sell, for example the reservoir pump for $20.00 include shipping? I notice that pump aerates as well, is that a special feature for that particular pump, or do they all aerate? How do you ship the parts?

It's $5.00 for shipping the pump and the aerator is a small hose that hangs outside the reservoir thus sucking air into the solution. It doesn't have to be used if not needed. 
I ship small packages US Mail and larger ones UPS.

What is needed to produce 600-900 heads of lettuce per week?

how many unit system you have times the growing life cycle of the verity you are going to grow.

example: say 800 heads per week. and it takes 8 weeks from seedling to harvest for the lettuce you want to grow.
multiply 800 x 8 = 6400 you would need a 6400 unit system greenhouse. you would start by putting 800 plants a week until the system is completely full and on at the end of the 12 week you harvest the first 800 heads and replace that 800 with 800 new seedlings every week. That is known as the Sea of Green method of growing on a large scale.

We are now organizing the 2001's China International Agriculture & Vegetable Fair in Shouguang City,Shandong Province, China. China has the biggest population in the world, and over the 60% population's vegetable consumption comes from Shouguang. The biggest national vegetable collection and distribution center is located in Shouguang. Shouguang's vegetables are sold to over 200 large or medium-sized cities of provinces. They are also exported to over ten countries and regions such as: Hong Kong, Macao, Russia, Korea, and the Southeast Asian Countries. Nearly 100 varieties of vegetables from over 10 provinces and cities are sold in this market. So it has become a center for vegetable collection and distribution, price formation and information exchanges for the whole country. Shouguang's Vegetable Wholesale Market was appraised as one of the 10 top specialized wholesale markets on subsidiary agricultural products in the country and was also called the biggest one in China. In 1995 it was named as "The Native Place of Vegetable in China" by the state. At present, more than 500 kinds of famous and fine vegetable categories from more than 30 countries, such as America, Japan, and Holland, etc. are being planted and produced in Shouguang City. China (Shouguang) International Vegetable Fair will open in Shouguang City on 20th to 26th April, 2001.There will be over 8,000 domestic enterprises concerned with agriculture, agricultural machinery & equipment (planting, breeding, aquatic food, fruit trees, green houses, seed, ecotype protection facilities, ecotype fertilizer, chemical fertilizer, pesticide, botany, flower, irrigation works, etc.) will be attending the fair. The State Ministry of Agriculture, the State Ministry of Science & Technology, the State Ministry of Financial, and the Governors in charge of agriculture in local provinces, will in attendance with their delegations at the fair. It is estimated about over 600,000 visitors will attend the six days of the Fair. The Fair will not only show the great achievements of vegetable planting and high-technology used, but also supply the best opportunity to meet the specialized enterprises for trading or hi-tech exchanging on the field of agriculture. You are warmly welcome to participate or recommend the enterprises in your country to participate the Fair. We regard this as a "Hot Commercial Opportunity", and it will make the enterprises much more popular in China--the biggest market in the world.

Please do not hesitate to contact us for further information.

Hi folks, here are a few real good tips I would like to share with you. most common Problems

These are the most common problems people encounter growing hydroponically:

Yellowing bottom leaves/older growth

The Nitrogen story:

Nitrogen is a transferable element (this means the plant can move it around as needed). If a plant is not receiving enough Nitrogen from the roots then it will rob Nitrogen from the older growth. In Hydroponics, usually the pH is too high and has locked out the available Nitrogen. Always check the pH before increasing nutrient level.

Save the plant: Leach! Check the pH, and adjust if necessary to 5.8 - 6.3. Check and maintain nutrient level. You may foliar feed (spray) with a pinch of CaNO3 (Calcium Nitrate) in a Litre of pH balanced water for quick results.

Leaf tips curl up

This is usually a Magnesium deficiency caused by a too low pH level.

Save the plant: Leach, check and adjust the pH level. You also may foliar feed (spray) with a pinch of MgSO4 (Magnesium Sulphate) in a Litre of pH balanced water for quick results.

Leaf tips curl under / leaf tip burn (browning)

The Nutrient level is too high.

Save the plant: Leach and decrease the nutrient level.

Leaching

Leaching should be done at every reservoir change and before countering any problem. This will rid the medium and root zone of toxic salt build up.

To leach, rinse the root zone with straight pH balanced water.

Use twice as much liquid as the hydroponic container would have held when empty.

I hope this info helps some one out there and thanks for all the info I have gotten from you all. Montana Mogy P.S. Ron I love the old bus.

OK here's another stupid "11 plant" question. Why is the 11 plant garden only suited for smaller plants? How come I can't grow huge tomato plants in it when the larger 1 gallon system still uses the same size grow cup? Would I need a larger grow cup to grow a large plant? What difference does it make if the roots are only going to continue to grow through and outside the cup anyway? I want champion size critters, not a bunch of small ones.

The reason the 11 plant isn't suited for larger plants is because of the distance between the plants (about 8") and not the cup size. By no means do you need to use the sizes I provide. Just cut the pieces of pipe longer to expand the distance between the plants. 
And the 2-liter uses 16 oz and the gallon uses 2 qt. size.
