Nice boards are those the king led??
Bro
look ur space is imho opinion too big for a first time light experiment... find very evenly spread reflectors
air cooled if ur in a hot area ... get digital 1kw dimables use at 600w ... get 2 or 3 depending on reflector .
de put out a shit ton of light and are imho the best lighting ...
... however the ballasts and reflectors are designed for comercial green houses to be hung very high up where heat dissipation can happen if u dont have 12ft high tent or ceiling
i did just see, again,
adjusta wing get into the de space with a reflector that detaches the ballast i believ
hydrofarm has similar as well.
bottom line is again get a ton of ligjt and get it now. U neverwill go wromg starting with 1kw dimmables... u can change in the future ...
just remember to use separate lower watt bulbs . For the dim setting ... i recomend justusing 600w mh /hps. Put one 1kw hps in the middle and two 600 mh on the sides with right reflector that should be solid for thst space ..
on the subject of temperatures....
.. im running active experiments on hps vs quantum's and i just realized my hps lights are actually running cooler in their air cooled hoods than the led.... by a large margin infact.
and thats not running "external cooler non grow rooM air through them....
If u need to control temps i do recomend getting cold fresh air in the hoods not from thr grow space, use insulated ducting... dump the heat in the attic ... and dont worry about odor control if your reflectors are good they shouldnt leak odor ...
From my very minimal experience so far Ied isnt that great at dissipating heat... yet . And the amount of led u would need for that space would produce a lot..
On another , head scratcher note...
i have heard cmh run cooler than hps ? Might be same reason mh runs cooler than hps?
This area of lighting alludes me .. a watts a watt . It is literally a measure of heat.. a light may put more lumins out but the wattage / heat wont change...
. Heat and watt are hand and hand by definition ?
can some one please tell me the temp of their cmh bulbs at bulb, and inches under becuase this watt for watt should equal heat . Am i missing something?
the only thing to disect here is efficiency
