a piece of wood, mounted on the wall, building a special electric box with dimmers and meters in it etc they all work.. I wouldn't leave it on the floor though.. the key is mount it so it can't move and disconnect wires.. also at a height that makes it easier for you to dim it.. 😁 I just noticed so...

"I haven't researched much on RO and when it's actually needed, I'll read up on that. My tap water is around PH 6, and 200 PPM...so I'm thinking it's not that bad?" My water is 280 ppm (on the 700 scale) and pH 8.1. I grew with it (in straight perlite in Hempy buckets) for a couple of years before ...

...a great way to help this is running a remote driver... mount it somewhere with easy access off the heatsink ( out side grow area even if heat is a issue ), and run a longer lead from the driver output to the boards input.. I'm going to set the driver up outside my tent today, where do you recomm...

welcome to the forum first off 😁 and I see a couple of the guys covered pretty much everything over night and while I was deleting spam this morning. 😄 but ill add a few things.. 1) yeah that's completely normal for a "a" type.. my bad 135w kit using a 120-54a can go to 134 watts and dims to 75ish ...

Sorry, didn't mean to mislead, those aren't qb, just diy LEDs in general.

Oh, well they shouldn't be so different to QB's. Guess we'll wait and see

That's quite the comprehensive shopping list for a first effort. Looks like you've got all the parts. How is your water? Will you need an RO unit too? When I look at your pics, it seems to me that you've built a light for a rectangular tent, not a 5 x 5 square tent. How does the light distribution ...

6. Personally,

Theres one foot to the ceiling. Gonna be interesting.

Geez, had no idea QB's could get that close!!

2. The board specs given by hlg are at 55 Celsius. Running them cooler than that will get a slight efficiency bump. 3. To fine tune the driver for max current: turn both pots up to max and let it run for a few minutes. When the wattage on the kill-a-watt settles (example 650 watts). Then turn down ...

1. Numbers sound right, nothing wrong.

4. RC only allows you to turn the driver on/off, not dim.

Thanks for the clarification on the RC. Much appreciated!

Hi all! I have a few questions for the QB geniuses out there, this will be my first grow and I’m confused about some stuff regarding QB’s. I just finished building my light fixture which is 4 QB288 V2’s from HLG running with a Mean Well HLG-600H-54A driver. Everything is mounted on a Slate 6 Quad he...
