Too hot!

MH only uses 6500K and HPS 2600K.

18,000 Kelvin is way too much.

i use a 18 000 T8 with my 2 6500 T5's and my plants love it. I often have to move the light or rotate the plants as they move towards the more purple 18 000 light.

BUMP
I dont think it is too much.
The question is, is it anything the plant can use?.
I think the plants will enjoy the extra spectrum.
any other users of this light?????

Are you using them for the veg or bloom cycle? Either way it is basically usless since you need around 3000 k or above and 6500 k max for veg.

i found a few timers laying around...at 5 30 am 1 timer turns on the lower kelvin lumins... 2 2300 k 42 watters and 2 2700k then 3 hours lqater at 830 am my other timer kicks on and turns on the day lite lamps which are directly over top the plant. 3 hours later my last timer turns on shining my 6400 and 65 and 67 ks and then 8 hours later . timers start switching off the lighst accordig to the atmosphere shielding the higher kelvin rays.,.. big perm!
