i also try to lollipop a lot, which leads to less bud sites and bigger buds.
a 320w 3 board quantum unit wold be perfect for your tent dimensions. Either King Brite or Meijiu brands which both can be found on the alibaba app. Are you looking for a full cycle light? Or a flower/veg only light?
I'm looking for a full spectrum. I already have a veg tent, but need it to to be both in case I need to veg longer. Thanks for the help, I downloaded the app and will see what I can find. Being only 5ft tall do you think I'll run into bleeching or foxtailing? For both I need the 3k right?
If you’re after a full cycle light then I’d suggest 3500k. Realistically you can veg/flower under any spectrum but the 3500k will be the best of both worlds for you. The 5 foot height limit definitely makes it tougher but you should be able to manage especially with the 320w dimmed down a bit allowing a closer hanging height while keeping the heat down.
No, I'm talking about the driver. You're just plain wrong. The closer you are to minimum driver load the less loss of efficiency.
You don't adjust the voltage to dim. We need a fixed voltage all the time or the light doesn't work.
You can use voltage for dimming on hlg cv drivers A-type. But its not really good for dimming, its more usefull for setting an upper limit of how much power each board can draw.
Yeah well I think I'm an idiot.
If they're lm301b's then you can use the converter on HLG's site.
Have you bought from them before? Just looking at both people they seem kind and of steep on shipping. I think with shipping I was only like $40 cheaper than the sf2000. If you had choose between the 2 which one would you go with? The US warranty work would be nice, but if theirs will outperform I'll have to thing about it harder.
I've used meijiu before. $325 shipped on a 480w r-spec QB knockoff.
Realistically I can only give you advice based off of research which I still have much to do. I’ve grown outdoors for years and indoor the last few. Coming from T5 and HPS, all the LED tech is new to me. I’m in the same boat as deciding which route to go. I was talking to one grower who noticed some mutations under his QB’s with ir and uv but at the same time I’ve talked to growers who use the same light and have had nothing but good things to say.
To be honest not too much difference. And also if you buy from one without buying from the other you wont have anything to compare. I sincerely rec thinking more about how to build for your space, taking account of hanging height and spread, how to handle the fixture (hanging/raising/lowering in a practical way) and how you handle environment instead of focusing on details in datashhets.
Ik its killing me ! Screw it ! I'm ordering the eb gen 2 560mm strips
Check out cobshopsgrows thread he has a cool little eb build. You and mikey should talk your in the same space. If youre going for heatsinks it could be a good idea to source alu which will fit 2 strips, that way you can update easier later. Building lights is a process which is great fun but if you try to figure everything out in one go you end the fun way too soon. Happy building and dont forget to ground your frames!
