I am going to start growing in about 2 weeks the thing is I only have 1, 2 foot, 2 bulb florescent fixture. I know this is gonna be good for seddlings but I wont be good later on. I dont have alot of money to buy HPS lights or any thing really better than floros. What I was thinking was to buy maybe like two more fixtures (about 120 watts) would this be better for growing. I WILL BE LIKE GROWING 5 TO 8 PLANTS. I am also going to put some reflective mylar on my walls to increase light. If there is any other ideas that save money but grow good please let me know thanks flp420
