getting temps down for summer? or?

[JointOperation]

ok.. so last year. i had trouble keeping my flower room temps low in the summer months.. even with a window banger.. i cant afford to put a mini split in. so its either.. downgrade.. and maybe run co2..

i was thinking.. either i am grabbing 2-3 600w ballasts and bulbs.. and running 600s.. instead of 1000s for summer.. or. i grab a few sunpulse splitters.. split my 1000s into 600w sunpulse bulbs. and run 2 1000s as 4 600s.. and run all air cooled and have a sealed exhaust for the hoods.. and then another exhaust or scrubber for the room? maybe even cut a whole in the wall of the grow and toss in a window banger to cool the grow instead of the lung room?

whats my best .. cheapest options to get my temps down for summer? i figure ill trade 1000s for 600s.. and just run a SOG.. im not looking to have the best harvest ever.. im looking to make sure i have a harvest for around outdoor harvest season.. just incase outdoors goes sideways.. ill still have smoke..

anyone else downgrade for summer.. or just go aircooled or ? whats your method for summer indoors..

aircooled hoods buddy that's the way to go!

I would go with 600 then bump it up to 1000 watt for winter. Have you thought about running your lights at night?

Run lights at night, co2 preffers temps in the 90's. Grab some ducting and run some cool air into your air cooled lamps from your air conditioner. Sounds like you know all this stuff already. I have a hard time kepping temps high enough for co2. Even with my inlines off.I vent in cool air from under the house with a little booster fan. Keeps things dry and cool. Good luck

Exactly how high temps are we talking? And what about the temps outside of the room?
If things are that bad then sealed hoods won't do much.
I'm in Florida and the difference in temps between air cooling hoods/no air cooling was negligible at best, for a grow room.

ya i was at a buddies house.. and he was using air cooled.. his lung room was at 70... and his room stayed around 75-80. running lights at night.. before he got his temps steady.. they were at 85-90.. but we bought this shit. to put on the hoods.. and it allows the hoods to be kept cool instead of them radiating heat.. and his temps went down 10 degrees..?

that's crazy.. hes using the same hoods im using XXXL Magnums.. i got 3 6 inch. and 1 8in converted to 6 inch.. i got my hoods used so i got what i got for 250 bucks for 4 XXXL mag goods.. so i use em..

but we said fuck it.. and shut down the indoors.. we tossed EVERYTHING besides a clone of each mom .. and 2 clones of the specials just incase.. and the only thing on is the mom 400w. i got on a fucking flip flop. . were every 4 hours.. it switches from a 400hps.. to a 400mh .. its a cool little setup.. keeps my plants nice and stalky..


put it this way.. the lung room of mine.. was staying around 70-80. depending on outdoor temps.. and this is with window fans. no ac.. i was thinking of cutting a hole and putting it in the room of the grow itself.. and just exhausting the lung room out the window with a window fan..

iuno.. i really wanted to have some indoors... so if i can figure out a way to get it cooled.. without spending a ton of money.. then im going to open her back up... if i can get a co2 system off ebay cheap. ill just run warmer temps with Co2.

Wait a minute. With or without CO2, high temps are not good for several reasons -1 being that terpenes evaporate more and faster. CO2 mitigates plant stress at higher temps, but you don't want to intentionally let your temps get higher to accomodate CO2. You're better off with temps under 80F with or without CO2. CO2 should increase the rate of photosynthesis, resulting in higher plant metabolism at any [none extreme] temp, vs. no CO2. Good luck. -granger

Studies have shown optimal growth and yields at 90-95°F, 1,500 ppm CO2, 45-50% relative humidity, 7,500-10,000 lumens/square foot of light, and vigorous air movement both above and below the canopy. CO2 enrichment under 80°F, under 7500 lumens/sf, or above 50% humidity is not recommended because plants will not be conducting photosynthesis quickly enough to benefit from the enrichment.

Thanks for the negativice rating and sharing your opinion. Science disagrees and so do my plants, haha! Have a good one!

That was qouted from Ed Rosenthal. Not my words. Has always worked for me, good luck!

[FONT=Arial, Helvetica, sans-serif]Freedom,
I apologize for bad repping your message. I seldom bad rep a message unless someone is abusive or something. Must have been the mood I was in. Sorry.

Your info on CO2/temp comes from good sources, but I think there are other considerations with cannabis besides optimal growth.

I think our methods will both accomplish what we intend. Good luck. -granger2 [/FONT]

not saying your entirely wrong freedom but a fair amount of mel franks work/data is dated
are those temps and Rh for bloom? veg?
temps in the 90s IS excessive even with C02.
from my own exp.I disagree Co2 doesn't work with 50% or more RH
many roads lead to nirvanna, right


i ran Co2 for the 1ts time recently,
i ran between 900-1100ppm
veg mid 80s Rh@65-70% and growth was phenomenal for soil
bloom same as above for the 1st 15-20 days
as buds increase in size rh was lowered and temps came down til I hit 30ish-35days
then steady temps 78F and rh 50% or lower...
biggest flowers Ive grown
no mold or pm issues

 

[FreedomTRAIL]

Wow, those temps and rh values are for bloom. You said it's your first time with c02, I would listen to Ed.

I was looking at your photo album,
nice job freedom,

Thanks gnome, you are very right! Gotta do what works for you!
