Starting a closet grow this summer and have some questions.

yea here is the link, its really easy to build and use, if you have a wal-mart then your set to build, and if you dont have a hydro shop your gonna need to use ebay for your ph meter, tds meter, and nutrients. Also you may need to get a RO machine if your your water is dirty, you can check this once you have a tds meter.

Thanks a lot! How much do you usually get off of that many plants. I am hoping for at least a couple ounces, just to last me and the people helping from the time of harvest til the time of the next harvest. And then I plan to use the leaves to bake with.
