Well the closet in like 6 by almost 3 but no more than a 4x4 footprint for this tiny light I think I'm going to prob switch to a 600mh and put this 315 w three other 600hps in my tent n compare its corner to the 600s

Just trying to veg w it to try her out for now but it's 3000k I'd rather flower w that but I was told it's efficient both ways they didn't have any 4200k

I'd use a 4k bulb for veg and flower. Not a 3k bulb for veg and flower.

I wanted that but they didn't have the 4K bulbs so what can I do ? I'm sure it's not the most efficient but I think it will work

The thing is my cmh bulb goes right into a standard mogel and spins right in as opposed to the special other ones

Do you find there is to much internodal stretch using the 3k to vegg?

I dont have a ton of experience but I just put up my 315 w 3k bulb and plants stretched quite a bit in first few days. I just switched to 4200k yesterday

I can say this about the 3100k bulb. And it has the highest par and is designed for flowering.

I'm planning on using the 3k bulb after this run to see differences, i was kinda dumb and bought the 4k bulb thinking it was the better option for me since i am using it between two 600w HPS lights. Also plan to buy a vertical reflector instead of using my blockbuster to see differences. I will post pictures when my run is done of some bud shots under these CMH lights.

Why would you use the opposite of what the manufacturer suggests?

Nice. When I build my new room in the basement next I will be adding a 4200k bulb to see myself too.
i went around and around on which bulb like everyone. Lol.
Some great growers are using the 4200k and raving about it but I think it's because the difference is likely subtle. And the little 315 is pretty impressive.
I have added the Hortilux blue mh to the room as well but may be switching that one back to hps. I have lost density and yield since taking out the Super hps.
I will miss the more natural light to look at the plants.
I am a believer fuller spectrum helps with quality but we need the strongest red peaks for proper budding.
The answer always lies in the middle of the 2 sides of an argument often in my experience.

Yea spectrum is important in my opinion , i really like the 4200k bulb its really nice for seeing stuff under it and the plants seem to be growing beastly under it. 600w hps produces nearly 3x more lumens than those hortilux blue mh bulbs, i don't use hortilux mh bulbs anymore, they don't produce enough lumens for me to spend that kind of money on them, i got these el cheapo bulbs that produce like 2x more lumens (both MH) with a slightly less desirable spectrum. The 600w MH bulb i use produces 60k lumens vs 39k for the hortilux. A 600w HPS bulb produces 90k lumens so it's almost 3x more than that hortilux mh bulb, that could be why the weight + density wasn't good under that bulb. I like those hortilux mh bulbs for veg only.
