It`s a no-brainer to go with the 18000 btu unit if it`s couple hundred bucks cheaper Bro , but here`s the thing.....
Each 1 KW bare bulb requires 4000 btu`s of cooling and dehuey`s range up to high wattage/heatgain if in the same room with the plants so.....
Let`s say that your dehuey`s up to 1500 watts of heatgain in said room and needs 6000 btu`s of cooling to offset it with another 8000 btu`s needed for the bulbs and you`rre undersized from the get with the 12000 btu unit...now that`s just for instance cuz I don`t know the spec`s on yer dehuey......but...
I missed the part about the dehuey bein all the way "inside" the grow area and even though the CO2 will be thru-wall , I`d see if yas couldn`t do the same thing with the dehuey so all heat exhaust will be outside the room as well , and then the 12000 btu unit would more than do the job for yas....but again...
Not sure yas can do it with your dehuey cuz all makes and models abound and are all built differently....anyways...
Quit crawfishin and crabbin goin sideways and backwards and buy the cheaper 18000 btu unit with inverter technology FTW and git `er done.....
Used ta be overkill`s not a good thingy with oversized A/C`s and smaller sq ftg , but with the new mini-splits with said inverter tech , it only makes sense ta get the cheaper LARGER unit so it won`t haveta work as hard to do it`s job and last LONGER as Mr D`s suggested even though Evlme knows his shit......
The dehuey`s the variable in the equation FHC.....always been prudent to air on the side of bigger`s better for all grow related shit EXCEPT A/C IME...in the past...but now....
Bigger`s better with the mini-splits for added environmental insurance........anyways....
Good luck....Freds....
. Those high seer units are attractive, but only if the btu rating matches with the amount of light and equipment being run. Besides it's never a good idea to try and save a couple watts at the cost of total enviromental control. Especially when you consider a an 18k btu inverter a/c that is only putting out 14k btu isn't using full power while it does it. Evlme2 stated there maybe higher btu units released by years end

....Yeah...sounds like blackmail I know , but hook a brutha up guys.....I wanna play too..........I need SOMEBODY to post FHC`s pics in this thread so I can see em since my proxy server won`t allow me to view
unless uploaded to the site.......and maybe....
I can talk him into updated kewl pics...
FHC....Walls of weed please.....
Peace...Freds.....
