New Grower Anyone else use a 315 cmh

[Hypathetical Gardener]

How does the 4200 compare to 3100 during flowering. Is the yield,density, and Trich coverage the same with the 4200 or better or worse than the 3100. I've heard the 4200 was great for veg but I haven't tried it yet. I'm curious about the ushio 3000 also. It's cheaper than the phillips also. I'm using a protopia 3000 right now. Its worked great so far with veg and flowering just started so I don't know about that yet. It was $49.99 so I thought I would give it a try since it was $50 cheaper than the phillips. So far I'm not disappointed.

I have a 4k bulb. I believe its growers choice or phillips... I looked at it close, it has a 98 cri and actually has more of everything than the 3k. I look to cri to decide. Plants seem to have enjoyed the sun spectrum for a few thousand years [emoji106][emoji106]

Think on it:
Does knowledge have intrinsic value or does it need to have a practical use to have value?
