I'm just using water.

I've got em growing in Miracle Grow soil it "Feeds Plants Up To 3 Months!"
So I'm scared to use any nutes. It also "Grows Plants Twice As Big!" If it doesn't work, I'm going to write a letter to the company demanding they send me an oz. of the finest herb they can find as compensation for their false claims.

I may start giving them nutes in a month or so...
Do you think that's a good idea?
