I know what you mean got tired of over half my crop disappear. That is why I laid off for a while. What lighting do you recommend for 60x60x80? How many plants?
@dbrn32 the light guy will say go with the HLG QBās.
I bought 2 HLG 260xl Rspec kits. The aluminum panel can actually hold 3 QBās and this means both panels with 3 QB each is good for a 5x5 tent.
I donāt know if he will recommend that one. I doubt it as they have light kits good for a 5x5 right off the bat.
I will have 5 plants in my 4x4 tent. By the time the other 4 get tall enough, the 60ā tall GSC will be ready for harvest and that opens up more space.
Ebay links not allowed here. Amazon, dealzer and aliexpress.
Iām also not super familiar with what is available in hid. I just know that bigger hood is better for 5x5.
Sorry. Did not intend to post the link when I copied the info.

Would 2 600watt be a better Choice?

Depends on how you use the tent. In most cases yes, but nothing balanced about 2 lights in square space either.
So, in your opinion, would 1- 1,000watt hps/metal halide be sufficient??? I just wanna make sure I have lighting covered.
Before I switched to the QBās, I had my 2 Viparspectra PAR600 lights at a angle which helped get more light to the bottom of the plant. I donāt need to do that with my QBās.
What about CMH? Or are they still too new.

I run 600 watt hps with old school magnetic ballists in xxxl 8" air cooled hoodsā¦
Hoods were $150 each and ballists were $120 each and 8" extraction fan was $75ā¦
I havenāt used cmh but if I was going to change things out I might go that rout ā¦
I just donāt know about the heat they put outā¦
I would use two 600 watt hps in that space or cmh ā¦
If your really good at training and scroging, I might look into QB boardsā¦ but again Iām not sure about heatā¦
Also if I went cmh , I would go with two 315 watt cmh so that you can have better light spreadā¦

They are all good lights. None of them really built for 5x5 though.

What size tent? How many plants for 60x60x80?
So, Final thoughts. What should I go with for a 60x60x80? 1- 1,000 watt hps/metal halide, 2-600watt hps/metal halide or 2- 315 watt cmh. I have also found a 945W CMH 3200k Double Ended 6" AIR Cool Complete grow Light kit. In yallās opinion, what would best suit a 60x60x80 tent. Like I said in the beginning, I just want to set this up to where I have sufficient light. I know that is a major factor, I will with your help, I hope figure the rest of it out from there.
Thatās what I have understood and I am waiting for his response, before I make my final decision. From everything that I have read on this forum, he is THE LIGHTING GURU and I will definitely respect his opinion. I am just trying to get the lighting situation as right as I can from the get go.

That is a smart plan. I didnāt join any forum when I bought my stuff. I have 2 Viparspectra PAR600 lights and now the HLJ 260xl Rspec lights. So a total of $1250 in lights.
Hindsight 20/20 can be a real b****. But now Iām on the right track.
I have always tried to follow the 6 Pās rule throughout my life. Prior preparation, Prevents, Piss, Poor, Performance. Definitely rules to live by, in my opinion

Iām not really familiar with the de cmh fixtures, so I donāt really know thd performance specs. If you limited to those three options I think you really need to look at how you will be using space and what you want to accomplish in it. I can think of scenarios where I feel running one 1000 would be better than two 600ās, then I feel the two 600ās would be better in different scenario.
Thatās really the issue with bigger spaces. If you had a 3x3 thereās a dozen fixtures go right in there and do well. And its easy to assume most can or will just have plant canopy wall to wall. Neither is usually true in a 5x5. A de hps is a great fixture for 25 square feet, but theyāre not really great in short heights like a tent.

If I was using a tent , I would probably go the rout of QBs , as long as I could keep the tent coolā¦ 
The reason I say this is for height clearancesā¦
