When you say 10x10 is that floor measurements? You will need 4-6 315w cmh lights... Will do a really good job... as good as ledIt's been a while since I've been on RollItUP I'm relocating to another state where I may grow cannabis. I currently do not grow. Although, I'll have the mean to acquire a proper Marijuana set up. I've researched time and time again,now I'm seeking professional opinion from the grower community.
My goal is not to show off on how much I spent,but more as the efficiency that I might achieve using a costly set-up. I want the process to be straight forward, cost efficient, while keeping in mind to being environmentally friendly(no supplement lighting/extra wattage). I feel theirs no point in growing if I don't grow with organic nutrients.
-With all that said this is my plan.

I have adequate information about the majority of items I'm going to use the thing that's bothering me is the grow light situation. I've decided no matter what LED is no good for me. I don't care how much science you put out there I want a spectrum as close as the sun I'm able to get I want quality!!!. Obviously, HPS is dead to me. In my opinion that's suited for commercial growers because they tend to pursue the most bang for the buck and growing strains for most output not quality. Obviously CMH is the clear winner here, but I here absolutely nothing about this light. My main concern will be heat issues knowing I only have 10 feet height.
Also, I have a few sativa I want to grow but that might be more suited for another thread....
Before youtube this was the place with all the info for growing so I came back with the master grow Journal which should start in August.

The full spectrum from cmh helps prevent disease. I'm going for the 630 watt cmh

Not trying to steer you. Just my 2c.
If heat could be an issue, remote ballast can help.
Consider fault tolerance and repairs, should a ballast or bulb fail.
Possibly better, more even light spread with 315 vs 630.
Jealous. Only wish I had space for a 10x10! Lol
If I did....a combination of cmh and strips would be my direction.

im designing 5 5x10s right now with 4 315s and a 720w board atm, unless i get sold on another led path
Have you considered the new hortilux ceramic hps 1000 de? I haven't run them but when I go to replace bulbs I might try them. I haven't seen or heard anything good as far as a 1000 watt equivalent for cmh. I love 315 cmh and have tried 630 de cmh and didn't care for them as much. I don't think the larger bulbs are reliable as they should be right now, but I haven't tried them all. But no major manufacturers are making large cmh bulbs. If I was gonna light a large area with cmh it would be 315 cmh but I don't believe you can hit the same numbers as you could with 1000 watt de fixtures. Im unsure of the spectrum of the new hortilux ceramic hps but it's interesting and it's by a trusted company.

Nice that light kicks the cmh butt. I'm going to research it

Well the website says do not air cool the lamps, It seems more suited for commercial grows.

Really? Which LED do you suggest?
Mars hydro ts 3000.... 4 of those. Or hlg 550 rspec x4
You need multiple lights for a 10 by 10... your not gonna escape that fact.
6 315w cmh would work well too

Ok, so you mean using a higher equipment cost to provide a lower energy footprint? Am I correct?
Something that can really drop the costs to produce is going to dry salts. I have found that with bottled nutes they are the second biggest consumable with electricity being the first of course.
TBH I used to be the same way with LED but I have seen what I can do with a good white LED setup and I was not only impressed by the yields but also the quality. I was one that was hard to convince that LED could provide the quality that I was accustomed to with HID but I believe now. I do think that you have to go with what best suits you though.
You mention heat, well with LED you actually have to run warmer canopy temperatures compared to HID. That factor combined with less wattage to cool can be a real difference maker when combating heat. Your whole efficiency scheme can really benefit from LED.
May I ask how you intend to cool the space? You are talking a 10x10, how many of the 1000 watt lights are you going with? Four I assume? Did I read that right, you have a 10x10x10 tent?

I want a balanced spectrum,cmh provides a balanced spectrum closet to the sun. I heard the science of what plants need or don't need,regardless I Still want a sun like spectrum. after doing a lot of research LED's doesn't beat a cmh, although they out perform hps.

I actually mean I don't want to do anything extra. As in 4 lighting units then supplemental lighting units, which is a little to extra to me and more electricity. Basically having a system and using supplemental is to much. Sell me on the LED's.
Hey there
I've been slowly replacing my 600w HPS units one by one. They just draw too much damn power!
I've been using a combination of CMH 315s and LEDs. I have big soil beds that are 72”x 40”,so I’ve got two 315s with two QB 96s from HLG in the middle. Four beds in a 14x15 room so I’ve got 12 light running total. I run the Galaxy remote ballast with the dimmable feature for the CMH and the 320-54a driver for the 96s which is also dimmable. I rarely have to run at 100% on any of them, and it’s really nice to be able to dim them down during transplantping and the likes.
While I may have gotten slightly better yield out of the old HPS, the quality levels of the potency has increased and the terpene levels are through the roof. And working under the nice, white daylight spectrum is soooo much better. It’s easier to see what's going on with your plants with them vs the orange light that HPS throws.
Also, the bulb life is awesome! No more replacing the HPS every 9-12 months, more like 3-4 years with the CMH.
Mainly, I did it for the power consumption. I can run 12 600wHPS at full power and draw nearly 55 amps but the same amount of mixed CMH 315 and QB96 barely pulls 35 amps.

What size footprints are you going to use in your tent? My flower is room is 8.25’x16’x8.25’. I’m going with 3 5’x5’ footprints but I also have the lights capable of that size footprint.

That's very cool to hear I'm happy the stories about the CMH are tru and the full spectrum achieves a way better quality. I'm doing all the research I can to find the perfect light with the best quality.
