If I were buying China boards I get meijiu 240 folux boards made up with all 90 CRI lm301b diodes and ELG meanwell drivers just in case i ever wanted to control them. The sunrise feature are good for softening startup loads and many have features of dimming based on temp. If the tent gets too...

Not on the 240w

If you're just going to use a timer or a flip box then it doesn't matter. But if you want to use 0 to 10 volt dim to off protocol like the gavita EL2 or TrollMaster type smart controllers you'll need 0 to 10 volt input

If you ever want to use a smart controller you'll need to get the elg driver not the hlg.

Man I can use some rain!

Lower down in the specs it says osram lm80 diodes

I brainstormed all the options back when I built the rooms given my budget. separate veg room does not work for my house. Especially when you start talking about having to move plants from one room to another. They veg in the flower rooms with the lights at 600 for 2 to 3 weeks before getting...

There's no separate room. They veg in the flower rooms

I used 2x 8in 650cfm inline fans one intake one exhaust on a tstat. No hvac

16 lights 24x24 and will also have room 2 that is roughly 20x20 and a 12 light space

I designed an intake/exhaust system that operates on dampers and a thermostat

That's not what geeklight would tell you

Sure I'll take some help If I use a 125a main breaker on these square d sub panels I will need to upsize my wire back to the main panel. If these run overdriven I'd be pulling 112 amps I think with 72k btu of ac. Even then 125 amp breaker wouldn't work.

I am tearing it down right now upgrading things and trying to decide if I sell off the HPS and go quantum boards. It's operating now unsealed no ac. The room cannot support running sealed with ac unless I go led.

22542w total HPS at 1000w with 5 tons ac 94 amps draw maxxed out. The wire between my 100a sub panel and 200a main is sized for 115amps it's 3c 1awg 1c 3awg aluminum. Not quite sure if that would suffice

Let me redo the math at 1000w not overdriven to 1150w.

ive not had good luck running 1000w DE's dimmed especially if i go to running these at 60%-75% long term. at 750w the hps is now about 30w/sqft this is better than LED's at 40w/sqft? if they are both sealed and running ac then HPS 1kw lights dimmed to 75% in 5x5 (30w/sqft) would be better than...

the investment would mean that i would indeed be able to power a sealed room if i went LED. since i cant with DE's

how do you run them flipped when they are in 18 hours for veg? 1 room isnt built yet but when its built out in the basement it will flip flop with the 24x24. so it will be fine when im running at 12/12 but what happens when one room is in veg 18/6? if i tried to seal room 1 now with 16x 1kw...
