Hello I can give some info,. what are you looking to learn, all in all its a fairly easy thing to do, So here are a few things i can help you with, First off Your Medium, Make sure it is a good Mix, I prefer Pro Mix Professional. Fox Farm was Ok I thnk the Pro Mix is the Best I have found, In all the years I have been doing it, Another thing is to hot I noticed seems I am Up here In Upper Michigan the cold makes my plants hardier believe me. It does seem I have used a 400 watt Hps in the pics also a 400mh, But I switched to 2 400hps I will post pics of them when done, also not to over water I find letting the medium Dry somewhat make you Plant Heathier.. Now I have been doing this for sometime now and found those few things essential. If you have any Questions Alex I can try to help the Best I can. Happy Growing "))
