So a 400w HPS couldn't keep up either? They would be right next to each other so they would share light.... I guess ill have to buy another 600w HPS if im gonna double what im doin... Hey georgia which hydro store do you use? Atlantis?

"The blue light from the MH promotes vegetative growth, it doesn't inhibit it."
I've noticed that MH make veggetataive plants more compact and tighter internodes. I was wondering, since the first couple weeks of flowering are a vegataive stretch would it help them grow compact and tight internodes.
Earthy Dank Reviewed by Earthy Dank on . 400w Metal Halide for first month of flowering? Okay, right now i have a 600w HPS which covers a 3 x 3 area. I figure i can fit 6 comfortably. I was wondering... could i double what im doing by getting a 400w metal halide for the first 4 months of flowering then switch to the 600w hps for the the main budding phase. Someone was telling me that plants grow denser with sturdier stems under MH light, and since the first 3 -4 weeks is stretching could MH light help control stretch? Could a 400w MH keep up with 6 medium sized plants for a month Rating: 5
