Interesting .. Do you also do aquaponics? I am South Africa based and have been doing aquaponics for years. That light cost how much ?? I also imported LED grow lights which didnt work at all I am not experimenting with my own CFLs and a dodgy LED i Purchased.. Nice one.. Cheer$;)
I think the whole kit, lights and hydroponics, was around $200. The kit is a few years old now so you might be able to get one cheaper than that now.
I would like to try and build a hydroponics lit from scratch.
