Hello, I am new to the forum and have been reading on it for about 4 hours so far and getting some pretty good information. I haven't started growning as of yet i am going in to this venture with 4 people who have their 215s and I have been doing the research so we can hopefully have a good harvest when it comes time. I have read everything i can on lighing and ferts and all of that stuff and i have heard from many different people who have grown before that you can give your plants some beer in the watering system about 1/3 a cup a day. However as a newbie i don't know if this is a trustworthy thought or not and would like to get a few of you Pro's out there to give me your thoughts on this process.
Thanks and i love this site i am looking forward to being here for a long time.
