The sweet peppers have been producing peppers for quite awhile. The plants are growing in 5 gallon buckets filled with water and nutrient solution. The plants are aerated using a pump in a battery box that keeps the pump dry. Even on the porch the plants have endured high winds and the hot Texas sun.

I change the water every 2 weeks and just add regular tap water in between to keep the water level stable. The food I use is SUPERthrive Foliage-Pro
