Just curious; what made you want to switch from your current system? Is it as simple as having heard better things about a flood and drain system, or have you experienced some deficiencies in the current drip system?
I was having problems with the drip system but the drip system is something that i fabricated and needs more time to be refined. I also own an emily's garden that i use for flowering which i am very impressed with. so i went out and bought the flood and drain system for my veg side that i guess you would consider prefabricated and proven to work well.
