dear ron,
some years back, i remember some scientist who live inside a glass dome for one year. part of the experiment, if i remember it right, was on hydroponics.
the main objective was to see if man can live inside a controlled environment, grow their own food and be self sufficient.
can you remember the project name and where i can get more details on this project ?
thanks
Dante Bugnutin W. Samoa

It was known as the Bio Sphere Project in Arizona I think. Just punch in bio sphere project in your search engine and I'm sure you will find something.

Ron, Do you have any tips or tricks for getting everything perfectly aligned when building the 11 plant garden?

A chop saw with stops helps to cut all the pieces the same size and I use a leather mallet to beat the pvc connecters strait when I glue them together.

hello my name is jessica and i am building your 11 plant system for a science fair project. i am almost done but don't know how to hook up the pump or how it works if you could tell me how this works i will be on my way to growing plants thank you very much

P.S. very cool site it is what i have been looking for almost 3 weeks thanks again jess

The pump sits in the solution tank because it is submersible. It connects to the garden system and when the pump comes on it pumps the solution up to the garden to water the plants. When the pump shuts off the solution drains back to the tank through the pump until the the next watering cycle.

Hey Ron,
Thanks for all the help so far. I am having a problem with my plants developing brown spots between the veins of the leaves. It started on some of the bottom fan leaves, now it's becoming more and more uniform. I am guessing a (Mg) deficiency but it could also be iron. Please answer asap I lost 8 of 10 plants to an earlier over fertilization episode. She is my last hope. I think the other one is a he and will have to be terminated.
Thanks bro,
Frank

The only sure way to correct fertilizer problems is to dump your tank and start over. Just because your ppm is correct doesn't mean that all the elements in your solution are correct.

Ron, I am planning to start with hydro this coming spring because I lost everything last year due to crazy weather. My location is CA high desert, 2350' short springs and falls, long very hot summers. There is no local supply store for plant food etc. for hydro or most other things peculiar to hydro. Any suggestions on stock I should have before I start, any special precautions I need to take regards the weather here. Thanks for any help....JIM 

You must be a hermit. Without supplies it would indeed be a peculiar hydro garden. A make-shift greenhouse made out of plastic and wood slats will save your plants from frost.

I want to grow large plants (2-3 feet tall indica) using net pots filled with grow rocks, set into a PVC grow tube. I am either going to use a deep flow technique (ebb and flow inside a tube) or airoponic using misters from Water Rite Products. My questions are: 1)Will 4" PVC, with 3.5" net pots inserted, provide enough support for a full sized plant? 2)For both airoponic and deep flow; will there be difference in growth rate between using 4" and 6" PVC pipe for a crop that is harvested every 8 -10 weeks?
Thank you for your time,

4 inch pipe is big enough for root room but seems like 3.5 inch hole would be tight fit in a 4" pipe so I would use the 6" pipe for more room. But remember the bigger the garden pipe the bigger reservoir to pump more water to your garden.

What kind of hydroponics system Should I buy to grow some kick ass green bud? (Marijuana)

Kind of hydroponics systems has nothing to do with growing KAB. What ever kind you buy or build you should try keeping tomatoes plants alive before you waste a lot of money on KAB.

Greetings can u suggest some good cash crops to be grown hydroponicly? also, how organic can hydro farming get?

First see what can be grown in your area then you will know if you will need a greenhouse. I grow tomatoes under shade cloth here in Florida to extend the growing season when it gets hot. Vegetables especially organic vegetables bring the best prices. Their is a number of organic hydroponic mixes on the market. I tried some years ago made from 10,000 year old bat shit. I'm glad I had an open greenhouse because of the smell.

I believe the green blocks used by florist to hold water for cut flowers in a vase are called a water oasis. Could this be used in place of grorox/perl./ vermic. ?

You can grow in just about anything as long as it's inert and can hold oxygen. The water oasis sounds like it's a perfect material for hydroponics if it doesn't brake down to quick.

hey,

I put my remaining plant into soil. It seems healthy for now. How often should I water and fertilize it now? It was used to being fed every hour.
thanks,
It's Frank again.

Frank let it get pretty dry in-between if the soil gets soaked it will drowned better to under water than over water just damp use your finger if you fell dampness don't water

Don't water it to much now. It takes a few days to root in the dirt and will go through a slight shock period so don't panic and keep over watering it. Fallow the directions on the fertilizer bag for your feeding schedule.

Does anyone know where I can learn to wire my own light fixtures? A friend has a light that her brother built a long time ago, but I am unsure if it is MH or HPS.

Any home improvement store will have how to light fixture books.

 Will a light fixture work for both MH and HPS, or does each require a special ballast?

Absolutely not. They aren't interchangeable.

In the 11 plant hydroponic garden, what type of timer is available to create an ebb and flow on a regular basis? The regular timers I have only have an "off" time and "on" time once in a 24 hour cycle. Also, what medium is used for the original starters in the halved plastic 1 liter bottle plant holders? Thank you very much, Bobby

They are hard to find but they are timers out their that have 48 pins that gives you 30 minutes on time and 30 minutes off time for 24 hours. Keep looking. I use nothing but grow rocks in the 2 liter garden.

Ron, yours is a great web site and I have learned a lot. I can see you get a lot of the same questions over and over. Now I searched for an answer to my question, but could not find it maybe you can direct me to it. the container that holds the solution for the 11 plant unit - what is the best way to create the access holes - I am concerned that the plastic lid will crack and crumble. thx j

Hey I know I  sometimes sound annoyed about the same questions being asked over and over but I know that my web site is so out of hand I can't find anything myself. So what the hell, what do do expect from a pot head. 
O! Sorry. I forgot about answering  your question. Damn that short term memory loss. 
If you put a piece of wood under the lid before drilling the holes it will help the plastic lid from cracking. Sitting the lid in the sun to soften it up before drilling will also keep it from cracking.

does anyone know if there is a solar powered pump , with timer available anywhere on the market, see with PRIVATIZED power companies taking over , TOTAL POWER BLACKOUTS are an all too frequent event, I guess my forest can live without a day of LIGHTING but I would like a SOLAR POWERED or SOLAR BACKUP POWERED pump so the feeds can still continue , unabated by the loss of MAINS ELECTRICITY. Thankyou Peltro pornocreep@usa.net

You can buy 12 volt pumps and timers at www.aquaticeco.com and then buy one of those car batteries solar chargers to keep your battery charged. Or buy a store bought automatic watering system for about 60 bucks from www.wormsway.com that will water up to ten plants for 3 weeks. You will have to adapt it for hydro because it is for dirt pots.

Hey man. I followed your advice on the 11 plt garden. But I got a little creative, and I dont think it was a mistake. I built a 4 bottle garden, planted 4/bottle to ensure I got plants, ended up getting 16 plants and they are all doing fine in a 2'/2' space, 5' tall. I also have them so close, the bottles are touching. I have not seen any stretching, just some thick-ass stems, and bushy-ass pot 'bushes'! To get them bushy I have been training the stems to grow in a spiral upwards- really cool looking. My problem is I need to start flowering, and I cant afford the HPS right now, so I need to slow down growth w/out affecting potency???Do I just take them off 24/hr lights and give them a break, (18 on 6 off) and ease up on the nutrients? Im not sure and Im not going to do anything w/out advice. They are about 15" tall and growing faster every day.

Change your light cycle to 12-12 and start budding with the light you got. Increase the nutrient strength. They will continue to grow another 5 or 6 inches while flowering. Sounds like you got a good strain for indoor growing.

What is hydropontics?

Do you mean hydroponics: 
Hydroponics, from the Greek words (water-working).   Hydroponics is a system of gardening without soil. 
In hydroponics, you provide all the nutrients to your plants through a water/nutrient solution.
There are lots of ways to apply hydroponics but, basically, all of them supply nutrient solution directly to the plant's root system. In most cases you mix nutrients into water and feed this solution directly to your plants.
Soil doesn't make plants grow. It's just something for the plants to hold on to while they search with their roots for
the food and water that's mixed into the soil. 
Since the food and water are randomly scattered about, plants have to use up energy growing ever-larger root systems to reach out in a constant search for these elements. 
In a hydroponic garden, a soil-less, inert growing medium is used and food and water are delivered directly to your
plants' roots. 
Your plants grow quicker and harvest sooner because they can direct all their energy into the vegetation growing above the surface instead of the root system below it
.

Hi Ron,

I have a dumb question: the "gro-rocks" I have tried (both the expanded clay and pumice ones) float on top of the nutrient solution making it difficult to keep them from overflowing the cups. Is that normal, or are the "gro-rocks" in Arizona full of helium?
gary

You are letting the water rise to high. About half way up the grow rocks is high enough as long as the plant roots get soaked. Actually the rocks that float are the good ones because they hold more oxygen.

i saw this site where they were growing plants in a bucket with the potted plant setting on top of an empty flower pot with two air lines under it the roots were just hanging in water & bubbles .the water lapped at the base of the pot the guy claimed incredible results i couldn't believe the roots. more root than plant just a little air pump. 

That's why I recommend putting an air stone in your nutrient tank to come on when your pump does because you can't give plant roots to much oxygen.

During the final stages of plant growth when you eliminate the nutrients to flush the plants of its taste, should you be concerned with the PH of the water? Rblack

If the flushing only takes place a few times no but for any length of time then yes, pH is always important.
I also never heard of flushing for taste.

With the 11-plant style does the intake and overflow have to exactly as you lay it out? I would like to move the overflow to another branch this should work...no? Rockyrackoo

Yes you can move it anywhere in the system.
