possibly the simplest, cheapest most reliable hydro kit u can make urself in 1/2 an hr
Well pleased with mine. Unfortunately they take up a lot of room - well mine does - so I can't set up the other 3 just yet.
Get urself a ph & ec meter to check daily = very easy to maintain.
Change solution every 2wks (ish)
luscious green growth - faster than my dripper - plus i can't smell the nutrients of this 1. My other set up makes the room smell like a rabbit cage
(it doesn't leak btw - just spilled a bit while i was filling it up!)
