Hi Chris
Nice set up.
When you are a bit more experienced at this, are you planning on growing the more expensive, harder to grow types of chillies?
Only at the moment it doesn't seem a very economical way (with electricity, cost of all the kit, nutrients etc.) of growing them if they are pretty much bog standard chillies.
IMHO they would grow just as well on a sunny windowsill/outside or would even probably be cheaper to just buy them.
As someone mentioned, Cannabis grown in this way would pay for itself and said equipment pretty quickly, especially as I believe it costs about ?20 for about 3 grams these days.
