Yeild of around 7 oz's, the smell is a bit of a problem growing LowRyder #2 and EasyRyders. As for venting I'd recommend venting out window because of nutes in the house, no they're filter worked okay infirst grow on this grow it's useless. EasyRyder stinks! If you're wanting to do sea of green method you'd need there old system I'd think. I you click on that pic I think it will take you to all the pic's and you'll see that complete grow and the on I'm working on now, it is 30 days old today. The forum I went to is a breeders forum and there's not much action on the board. I've done this since I was in my teens, old bastard now so I had s few basic questions. The best way to yeild the most decent weed it to cut above second leaf or what you're talking about and I'd much rather have the HydroHart System in 72" cab just me. You may reach me here and as for pic's just click on any of mine and you should be able to find all. Best of luck.
