need advice

been growing with a 400 mh/hps. i force flower so i end up with about 2 1/2 ft plants. gona upgrade my room. 3 by 8 with a light mover i would like oppioniond on weather to use a 600 or 1000. and what heigth could i finish them at with that light. i curently use a 8 inch vortex fan with c filter in a vented light hood

thanks guys

i have a 600 watter in a 5 by 5 area and it grows my babies about 4"ft tall and nice tight buds on the top quarter of the plant a light mover is a great add to a perpetual grow you add like 1.5 squar ft or m i cann't remeber but im going to invest in one it also gives a better light dipersion in your canopy getting light to the plant at different angles my boy have one and some clai crush plants that seem to follow that bad boy but he has a 1000w on a mover set to damn slow. if you light is vented how far away from your babies are they?

i keep my 400 about 4 inches from top i see no bleaching

for a 3x8 i would get 2 600's without any light mover

yeah i had thought about that also .....about high can you flower with a 600

huh? "about high"? you mean the height of canopy? more than you need in height, you don't have to scrog maybe tie some theyre even more efficient than 1kw in terms of lumen/watt

yes canopy height i just top when young and start flowering at 16 inches now with my 400...wondering how deep a 600 can penetrate compared to a 400

any more advice?
