Yeah thats just it.i dont want air con..so its light burn they get yeah from too
much heat being too close,is that what you mean?as what ive mentioned
I have a 710 cfm extraction fan for an area no more than 230-240 odd cfm .

Power aint cheap here .would dimming light b less efficient..it doesnt look
like im gonna get one anytime soon.yous might have to yell at me in big
letters lol. Go /#@&ing buy one you anal barsteward

I think that exhaust would be adequate as long as the intake air temp is reasonable (80f -). There’s the gavita 6/750 too that goes up to 825w I believe. Do it right you could pull 2units off that no problem. Would likely need co2 supplementation to hit that which is tricky/wasteful in a vented room but doable. What’s it cost to fill a co2 tank where you’re at?

You want a 20lb tank with a solenoid
if your going to run pressurized can often find them used. Just make sure they are within date and you will need a controller for it. I'm drunk k and gi so if this makes no sense then... well I'm drunk and high so yeah.

Uno Pharm ,i was looking at that fixture earlier.that could be the answer to the height and a little less heat.says it covers 1.5 and at 750 its 1500 umol

Says input power 795 at ( 100%) 870w (110%) .
So should i get it lol.the more i bloody think it gives me time to change my m8nd lol.

Get this god damn light out of way .you guys can fill me in with this co 2

Hmm.just noticed its a complete fixture..:badboy:..
Could this fixture be hung say 45cm off canopy.sux that ballast is vertical .wastes
precious room.

Just looked on the gavita home site and it says the spread is 3x4.5 ft at 2 1/2 ft
Mmm they waste precious space..

That’s rated that way because of the factory hood it comes with.

The hood on the right is a factory hood. See how steep it comes down till it ends. That hood gets less canopy coverage then the left hood. The left hood is more open with wider coverage. I canned all the factory hoods for the one on the left. I believe the left hood gets a 5x5 coverage if I’m not mistaken.

It looks like gavita discontinued the remote ballasts can’t see em on their site... But yea that’s a complete fixture. And 3x4.5’ is a very conservative number I’ve got the 1ks on a 5x5’ and it seems like too much light I’ve never even had it past 1000w. And you put that 150wide angle shade on there diesel showed your footprint is even wider. The ballast being vertical does sacrifice some height but you definitely don’t want the reflector touching the ceiling anyhow it would be a fire hazard. The ballast doesn’t make much heat the 1k ballast makes 60watts of heat which is piss all 750 even less

Yeah i came across that earlier post #36 .i was smashed at the time when i think i looked on the growers house site and it said discontinued but underlined at the bottom of the sentence it had the digStar e series as a replacement.and seen this

Probably just cuz they weren’t selling enough compared to their complete fixtures. Hawthorn aka scots miracle grow/Monsanto/Bayer bought them out a couple years ago now their just cranking out the complete fixtures

I see now why you mentioned co2 Pharm.more heat is required and favourable when running co2,plants are more heat tolerant when using it, but some plants are better at it than others.i have been looking at the cooltubes and how the ducting works and takes just the heat from lamp than the room...gee there more one than way to skin a cat hey.
I like this....expensive to setup though..
Maybe i can do something like this down the track as once i get a year or 3 under my belt
I can improve the yield further...i cant wait to start..
