CMH is HID, it's basically evolved Metal Halide technology. I quite like CMH for smaller setups like big tents and small rooms. For large rooms though I really prefer 600 or 1000w HPS for flower.Can you share what you think of as the biggest difference between HID and CMH?
And your thoughts on what would fit well in a 2 Gorilla 5x5 with 9ft extensions? One for flower and one for veg.CMH is HID, it's basically evolved Metal Halide technology.

Where I do think the LED technology shines though is in small tents etc, where heat is a concern. I suppose part of my love for HID comes from the perspective I'm looking at it from. Usually larger rooms.
But even then, I still use 2x1000w HPS in my 8x8' which I consider to be a fairly small room.

You just caught my curiosity on the subject when you brought up the fine point of rock hard frosted buds. I have not seen the Jesus LED yet that can perform that miracle and has been what's prevented me from making the switch. I will say that the person that brought up the Gavita 1650e has gotten my attention on that. I have the Gavita 750 Flex and it has done me well under those conditions but the power bill is getting up there ya know?Man, there is so many ways to skin a cat and not many people would do it how I do these days I dont think. Personally, I'd use a 315CMH or 400MH in the veg tent, and I'd put a 600w HPS hung vertical in the flower tent, maybe even a dimmable 1000w, but I think the 600 would be sufficient.
Again, that's just the hardware I'm familiar with. I really dont know squat about LED but I suspect that might not be a bad option either. To be honest, Tent growing and LEDs are my least favourite subjects lol. I know FA about it.
Oh I agree. However I have seen those same genetics turn into cotton balls under LED's.Part of growing rock hard nugs is having a strain that produces rock hard nugs. Some strains won’t no matter how hard you try.
Yep, as well as environment besides lighting. Hotter rooms grow more fluffy. But I will say 80% of the strains I've grown turn out quite tight. only the pure long flowering Sativas tended to grow fluffy for me.Part of growing rock hard nugs is having a strain that produces rock hard nugs.

That depends on the quality of the LED's and the growers skill as I have found that my bud density greater than that of runs under 750 watts of DE HPS, not to mention the 5 days faster finish time. I'll easily harvest a kilo of fine herb from my modest 530 watts of lighting.Oh I agree. However I have seen those same genetics turn into cotton balls under LED's.
I don’t even get why someone would hang a quantum board that far from their canopy. The whole reason quantum’s are more efficient is because they can be hung closer to the plant and waste less energy by doing so. By hanging the fixtures so high they are losing the advantage and might as well go back to HID to get better results. Imo it’s a mixture of old school growers still adjusting to new school technology. But that’s my opinion.
When there are enough lamps in the room properly spaced hanging them high more fully saturates the room with light from more angles.
With few lights distance becomes more important and so does plant structure and arrangement.
Thats why light movers are effective. More angles of light covers more of the plants.
Light rails or movers are weird to me. With LED you can "just" add more diodes and lower amperage and cover it with psychical light and probably save a good penny on electrical that might take a few years to pay for the investment into LEDs. Nothing is perfect and spending up front money when theres tons of de hps units used for not very much at all is tough for some people. The lack of UV ligbt seems to be a issue in peoples opinions too but you can add uv really cheap. Long way of saying theres no wrong ways in my opinion
I always wondered why the comecrial growers put their lights so far from the plants. The only answer I could find is that because there is so many lights the needed PARs are gathered.

Video won't play for me. What is the finding/conclusion?I always wondered why the comecrial growers put their lights so far from the plants. The only answer I could find is that because there is so many lights the needed PARs are gathered. Then I watched this video

There is definitely benefit in overlapping lights but I doubt you lights are 10 feet away from the conopy like I think I've seen in some commercial growers videos.I think that there is much benefit to a bot higher overlapped light. My yield per plant went way up when i added a second lamp at the same height.
