Good Morning. I have a 2 x 4 x 6 tent. I started with that Phlizon 600. Then I realized it's not that great of a light so I got a Maxsisun PB1500, after watching that dude that actually tests the output & calls these companies out for bot being accurate with output they advised in advertising. The Maxsisun seemed to be decent for the money. I was starting on a budget. Although now I dont have a car payment anymore. Woot Woot. So I will be getting even better stuff in the future. I did not realize how much I would fall in love with growing my own. Anyhoo, this PB1500 is not too bad for 1 plant I feel. & Yea, I learned real quick. & still learning. I bought Ed Rosenthals Growers Handbook & am halfway through. If I would of had this book before I started this grow. I feel I would of known better or atleast how to understand the deficiencies or nutrient problem I had. & I also would of never had "flush" in my mind & starved my girl for a few weeks. Meh. She's now back on the nutes & looking better. Thanks for all your advice. I stay on youtube, trying to learn & soak it all up. Cheers.
