Okay, first hand info. Thanks. What is your driver setup? I'm already committed on the 2 HLG-320-54-A... My grow space does have quite a bit of headroom and heat won't be an issue, not until summer, at least- even then I have ways to pump AC directly into the tent and at the lights. Portable AC units and I made a ghetto attachment that fits over the output that connects to 6in duct.
I use two HLG-240H-54A's with 3 QB96's on each one run in parallel. I'm not sure what the max output of a HLG-320-54A is, but my 240's will crank up to around 300 watts when set to full.
What is your ideal height above canopy running them softer ~80w?
I'm still trying to gauge that, and of course it's going to depend on what point in the growth cycle they are, but so far 12-inches seems to be ok (I don't really want to get any closer that that).
Good to know. I’m in the first week of flower and was running 140w per board and they were looking a bit stressed at around 18-20”. I’ve lowered them to 120w and raised the light to 28”. They are on a 320h-54a, I plan on adding another 2 QB 96s to it soon so I can run them softer and get better coverage.
I appreciate it, but if you read the thread I've already bought my lights. I'm not going to lie, I like that those have controllable UV.
Actually the HLG 600 Rspec is on sale. It's about 720 out the door. That's 70$ more, but I am getting an extra 120 watts over yours... So nearly the same except I traded off some the UV spectrum for more power. Pros and cons to both.
If it was me I'd get those bolt on HLG ones. You don't need UV, but it will help make frostier nugs. The frostiest nugs I've grown were with CMH, but my favorite is QB's with CMH now when I can get away with it. I'll get some HLG UV lights someday and compare. But I know if I added the UV they would be better.
Yeah I'm probably gonna go that route. I can only find UFO supplements and I'd need like 4 of them, 1 for each corner pretty much- too complicated compared the the HLG. It will be super easy to place compared to another bar. I'd have to place a different one beside my QB and only half the tent would get good coverage with 1 fixture. With the HLG it snaps right under so it can be in the middle and it's designed for 4x4 coverage at the same height as the board. I know the UV is definitely not needed but that frost is what I'm after. Gonna wait on that until I start flowering, though.
I'm freaking jealous. I don't think I can just clip them on my 260's. But if I had yours I wouldn't be able to help myself if they just clipped on. They'd already be on a credit card, lol.
