solar powered 5 gallon bucket planter

Update: April 20, 2013

I used lava rock and perlite in this tower. The solar pump kit was on ebay for $15.

I have tried different ones and this is the best of them. I filled a sock with compost and placed it on top where the water flows. I use 1 tsp of nutrients in the 5 gallon reservoir that I change weekly. I mix 4 parts miracle gro for tomatoes 1 part Epsom salt and 1 part calcium nitrate to make my nutrients.
