For Veg - 315cmh 4k Or Hlg65

[NHWhites]

I flowered put my last round with a 315cmh using a 3k bulb. For veg this round, I’m either going to get a 4K bulb for the cmh or pick up a HLG65. I’m leaning towards the 4K bulb but the hlg is intriguing. Anyone have thoughts on the best course of action?

I use a hlg65 4k in a 2x2 tent for veg and its nice but the 315 is more powerful and would probably veg bigger space,bigger plants,not sure of faster veg though.

You should get a lot faster growth with the 4k 315 cmh. I cut 2 weeks veg time off from 600mh use.

Still haven't used a cmh but I know the hlg QB is better than the blurple led and cfls I used in the past.

You can't put hid or cmh in the same realm of reality with a blurple led light. That's like having a crappy dodge omni vs a Lamborghini Gallardo.

I'll have to get a cmh once I can setup my 4x4 again,it's the only type of light I haven't used yet. Although I'm really kinda stuck on these cobs and quantum boards,they are f in awesome.

Iirc timber are top quality. All others, unless built by gt, may not be up to par.

I still like cmh performance and color. Timber is popular and people i know build great kits .. Im not gonna go all best in the world on it though.
