so i have Metal Halide 250W with colour temperature = 4500k. is this MH best suitable for vegetative or flowering? and my 250W HPS has colour temperature = 2000k, is this HPS good for flowering?
MH is best suited for vegging. HPS is best suited for flowering. Are you sure on that color temp for the MH. Sounds a little off to me.
yes im sure, my MH is Philips Master HPI-T Plus 250W/645, the spec was exactly the same from this website http://www.nimax.co.yu/files/File/sijalice_brosure/2_56.pdf i've read many good color temperature for vegetative are around 6500k/daylight. but i just found that my MH only had color temperature of 4500k, so is this MH not worth for vegetative?
