I need advice on which bulb to use mh or hps

I have 2 plants that are in flowering stage amnesia haze autoflower I have 6 seeds that have sprouted can I still use my hps bulb or do I need to switch back over to my MH bulb or is it ok to use the hps bulb for now till my sprouts get bigger ?

Ideally you would flower under the hps bulb and veg under the metal halide bulb. If you have to run all plants under the same bulb just decide if you want to focus on the flowering plants or the vegging plants

My flowering plants have about 3 weeks left if I have done my math right would that effect them flowering if I switched back over to the MH bulb ?

If u have ur flowering plants under hps, u can switch to mh for last couple weeks. Alot of guys reccomend switchin back to mh for last 2 weeks of flower.

What are you k spectrum on your bulbs?
I run 6000k or 6500k bulbs for veg and 2000k hps bulb for flower.

It’s a 1000 super hps bulb so I’m not sure honestly

@tanlover442 I believe it boosts trich production. It did for me anyway way and I’m gonna keep on keeping on with it! :v:Happy growing my friend :sunglasses::call_me_hand:
