supporting the plants
 

Ron, I will be growing my plants out doors using your 11 bottle system. It seems to me that once the plants get so tall they will become top heavy. How do you suggest supporting them especially during a windy day or a thunderstorm? Thanx D.

You need to build a stand from 1 or 3/4 inch PVC to sit the garden on. Put the tank on the lower shelve to anchor the stand down with it's weight. Add the risers to the bottom stand that will hold the top part. You can tie your plants up using the stand and even hang a light from the top of the stand.
