i've been debating the 3x 600's (2hps/1mh) vs 2x 1000's hps for this 6x10 room... a lot of heat either way i guess, butso you don't ventilate anymore after installing the thru wall a/c, even for "fresh air" occassionally in veg/flower? i have a thru wall 6500- just figured i'd leave it on 24/7 (fan always on, cool cycling @ 80F), and yes use the individual controlled humidifier, dehum, vortex heater fan, etc if necessary. i thought co2-4e control hooked to inlet damper/hepa & outlet fan, sync'ing with co2 off, to bring in fresh air for ~10 minutes every hour... but if others with a/c can grow well without having to bring in regular fresh air (no $$controller$$ necessary, no $$co2$$ exhausted) ?!Endless..
Despite having vented hoods, three 600's and a dehumidifier still get the canopy temps above 85. I was using the xgc1 for vent control. (one inlet and one outlet fan) but yeah, I hated wasting all that co2 so I finally installed a
small window AC in thr wall. Even though it doesn't run that much, definitely NOT the best option and will try to install a spilt AC unit this summer.
To be honest, the xgc 1 is great but the only things I am using in it are the co2 and hydro cycle timer. I got mine for $450 or so via craigs list, so still an awesome deal but if I were buying new ibwouldny just make sure all the things that the XGC1 would have controlled have built in controls. (ac, dehumidifier, heater, pump timer) etc
Thanks for subbing! I actually reconfigured everything last week to take my veg room out of the flower room so i have more room for buds
is there a benefit of split a/c over thru wall(window) to the grow room? other than possibly energy efficiency or compressor noise i'm curious. my little a/c is closed loop w/ no vents allowing outside air into the room (ideally, except for tiny gaps in housing of course).
how long do you use, or when are you starting/stopping co2 usage in growth cycle?
how/where will you veg now?

Lol. The only "fresh air" that my plants need comes in a #20 lb tank in the corner of the room.
Split ac units are the SHIT! No air exchange, super effecient, and they take up little space. The biggest issue with the regular air con in the wall is that it pumps heat and ALLOT of moisture into the house. Like allot. My co2 usage is 7-800 for first 2 weeks of veg, then around a 1,000 for weeks 3-4. 1,200 for all 12/12 except 1500 for weeks 4,5,6. The last two weeks I am planning on using around 600 tops. I have read some negative reports on the effects on high co2 during the ripening phase.
Cheers.
Oh yeah, that is an odd dimension for a flower room size. I would go 600's if you don't have much height. 1,000 if you do.

no air lol. and damn man, you must have a big stock of co2 tanks in storage?! any reason you don't use a co2 burner? wait i thought plants need oxygen at night? guess you prove that one wrong. so i don't really even *need* a ventilating timer...!?
ya my room & a/c are in the garage so temp/moisture are no biggie... and the damn garage door track limited to 7' high...
hey didn't you say you travel? if so, how do you control/maintain water chemistry while you're gone?

The CO2 shuts off at night (obviously) so the plants have plenty of o2 to respire. Water chemistry isn't such of an issue. If nute strengths and grow medium are all dialed in, PH doesn't raise that much. I have a mechanical top-off tank that I can attach to my reservoirs if I need to leave town. Sometimes I keep the PH of the top off tank a little lower if I am in early veg when PH seems to rise a little faster.
I have access to a co2 burner but need to install a split AC first to combat heat issues before I install it.
What kind of insulation do you have in your garage? I would think off time heating would be a bear.

i guess no fresh air in makes sense though; the plants are making o2 during the day with co2. so if its sealed its just back and forth co2<->o2 aye
50's home so no insulation in the garage (or house!) walls lol. but it's a new room w/r-13 all around IT... kinda wishin i would have done 2x6 & r19 but then the room/ceiling would be that much smaller +more money.. so it is what it is now. i insulated cuz i was worrying about wasting even more energy/money (here in SoCal where they rape us on cost of everything) climate controlling with the extreme outdoor temps here from 20's-110F more than anything; but just did r13 since it isn't quite as extreme being inside the garage. at least the a/c was free. but with the a/c always "on" with the fan running, cooling cycling at like an 80F setpoint i didn't anticipate overheating. figure i can just lower the a/c setpoint if i need. separate light air cooling path and all... your room overheat with your a/c on?
man i was trying to decide on if/when to ventilate for fresh air using a fan/co2 sync controller like co2-4e (which also has over temp &hum. to turn fan on), but now you've really got me wondering if i need that at all and can just keep the room sealed up with a/c (and probably separate dehumidifier), except for me in/out the door... the less outside air the better regarding disease and what not if you ask me. but even if i don't regularly vent, i think i'll might still get it (tomorrow maybe) just for the overtemp control... gotta get this room goin!
i dig automation and all too... i was looking at something like the hanna 9913 to do ph/ec in this room (the less i have to even open the door to go in there the better). or their BL981411-1 for pH is only $90; just need to find the other crap to go with it.
i'm thinking of a burner too to not have to run out for tanks. hell its not much more than buying tank/reg/solenoid and crap with a whole lot less hassle. i'm just not sure which one or how well (or even how) it is controlled by something like the cap ppm-3

Little update and will post pics soon. Bud glands are starting to swell up nicely. Some at least, you can see them sparkle from across the room! I damaged the stem on one of the smaller buds and it was dryer out on top so I cut it off. Wife smoked a sample (god damn weed fiend I tell ya). She looked me straight unthreatening eye and said "dude" " it's fucking dank" no, I mean it, i was a little caught off guard. 
.
Probably the nicest thing she said in awhile. Got 12 plants fully begged out and waiting to flower in the veg tent. I FIMd at 4 nodes and there is probably 6-7 main shoots on each plant. The average height right now is 15" so they are going to get flipped immediately as soon as I clear out the table. I have been tying the dominant shoots down to bulk up the secondary stems. This seems to be working pretty good although it can make them want to stretch a little more.

Little more bud porn and pics of the plants on deck.

hey man,yeah well I just discovered bud rot in about 5 buds
first off happy new year. don't panic. isolate the buds if you can by manuevering them. drop the humidty below 40 %. this shit happens when you grow fat ass bud. sometimes the buds grow so big on a stem they overlap and almost suffocate one another. sometimes they trap moisture too. I've got to hand it to you dude. you made some nice ladies. congrats and happy harvest. dont sweat the little stuff. some of my best grows have minor shit like that all tyhe time. 5 bad buds outb of 100 is 95% A+. Like you said alls well that ends well. excellent room. excellent grow. excellent post. Rep+. Will chime back in to see final yield results. Great job legalbeagel.
