Hi I am looking into buying a small hydro kit (4 plant) and have a few questions, 1, Roughly how much weed can I expect to get from 4 plants? I know this will vary as to what seeds I use but can anyone give me a rough Idea? 2, Are these all-in-one "hobby kits" actually any good? The one I am looking at is from www.growell.co.uk and is Â£150 Sorry if these questions have been asked before (I'm sure they have) but its easier to just ask again than trawl through loads of old posts, especially when stoned and got a slow net connection! Thanks!
