Scrap the metal halide?

[Banana444]

I have been using my 400w metal halide 36000 lumen bulb alongside a 400w hps 55000 lumen for veg in a 5x5 area. Am I better off switching out the metal halide for the added lumens. The hps bulbs say they are spectrally enhanced.

I like the way the MH works in veg. IMO the HPS makes the plant more lanky

i agree w daggy, mh's are great for veg, they tend to have tighter nodes then hps', but man, you should run both of them during flowering if you can, you'll thank me later..

Thanks, I guess I will keep it on, its a brand new bulb, I only used it for a week when I first got it on my last grow, before switching to flowering. I didnt add, I have a 600w 95000 lumen digital bulb that I am going to add when the plants fill out more, along with either the 400w hps or metal halide, but you think I should keep the metal halide the whole run? I will add I have a couple of autos in the tent. Its a 5x5x7 with 4 15gal pots and 7 5 gal buckets soil grow.

yes, although i've never done it myself, i've read numerous times that plants that receive both mh and hps light are usually the ones that do the best out of entire grows.... like i've read where they have an hps covering x plants, and and mh plants covering y plants, but the plants that fell more in the middle, the x and y plants, all did the best.. i'm dying to run a test myself, but as of now, don't have the room to do so.. mh's have more uv light that hps lack, and hps tend to have more red light, which is better for flowering, so the combo of both is great for plants from all i've read..

I wouldn't mix spectrum for flower. The loss of red spectrum and lumens wouldn't be worth the UV IMO.

Well I will likely switch to the 600w hps and leave the metal halide in until I switch to flower. The two 400w lights are in euro air cooled reflectors and its been staying a cool 76° with them both on. Things are taking off too.

Run the mh until second week of flower. Then switch to hps.
