Hi Ron. Got the 11 plant "Pocket Hydro Farm" almost complete. Very neat stuff. Am having trouble finding the 2 liter plastic bottles as I don't drink much soda pop. Now if you can design a beer can system I'm your man. I plan to put tomatoe plants in it and am in a hurry to get started. What kind of tomatoe seeds
do you think are best for hydroponic systems. Thanks for a outstanding site. T.R.
