you can make ur own hydro setup. Check out some of the stickys or the PGAMG thread. The stickys should have set by set setups for bubble buckets and what not. The pgamg has a quick explanation with some pics of my setup. It can speed up growth if done correctly. Once its setup, imo it's easier to take care of than a straight up soil grow. All you have to do is change the res every week and add nutes to ur water. Definitely worth it. edit with links: big poppa puffs bubble bucket method 101 http://forum.grasscity.com/showthread.php?t=35309 PGAMG - look at the beginning http://forum.grasscity.com/showthread.php?t=84490&highlight=pgamg
