problem after problem after fuckin problem.....

im kinda new to the indoor hydro game, but i got alot of friends who been here and done that, and its helped me overcome some of my room issues, but there always seems to be a neg. to everything i fix.

im sure there is more info here than any where else, so im politely begging for some help.

here is my problem.....

i have a 2 light set up (1000w) over 2 4x4 tables, 12 bubbas per table, 20gal rez each. automated drip system runnin 1 time a day for 20 min. at first i was ducting the air tho the carbon filter intop the lights and out the room, worked good too. but i had to make a step up to co2. so i changed it to pulling fresh air from outside tho the lights and out the room. the filter now runs on its own in the corner. right away my humidity jumped trough the roof (70-80%)
and temps went up a lil due to the decrease of air flow, now the room is sealed off and co2 is up and running (1300 ppm) man what a difference too...

but this set up is a constant battle for temp, and humidity, i have a huge dehumidifyer and its working to keep it down in the 50% range, but that thing puts off some heat, pushing temps to just under 90 when lights are on, and low 80 when there off.

i know a 2 duct a/c unit might help, but the cost of the unit, and power to run it is quite scary after the bills im getting already.

i know the co2 works a lil better when the room is a lil warmer, but whats the limit, im in my 2nd week of bloom now, and im very nervous i might ruin the crop if i dont know my limitations......

please any advice your pro's could share would be greatly appreciated....

thank you in advance...

a picture is worth a 1000 words, so here ya go...

CO2 runs much works better with the temps in the mid to high 80's.

Could you maybe run a vent fan on a timer, you will lose some of your CO2, but it will help with the temps and the humidity.

It sounds like you put in alot of effort, hope it all works out for you.

i have a green air controler, and it runs the co2, de-humd, and has a knob temp setting for a vent fan, i have a 50,20,15lb tanks so i got alot on hand, maybe ill give it a shot, when the controller fires the vent fan, it kills power to the co2 meter, so i dont waist to much, could it be that easy...?

It will not hurt to change out some of the moist air.

Alot of people vent their room several times a day, they just shut off the CO2 for the time that they are venting.

Rapid growth means your girls are drinking alot of water... What goes in must come out...

Sounds like it could be that easy. I run a window ac unit that cools as well as dehumidifies. Now that it's getting cooler outside and my AC is off my dehumidifier is working alot harder.

I have found that a sealed enviroment benefits from an environment controller.

Having a central controller instead of all of the internal, thermometers, hygrometers etc.. really helps you dial things in easier.

First you will need SPDT thermostat, one that will power one item when its warm and another when it is cold. Sometimes Lowes/Home depot/wally will have them, they are the 120v ones they use on baseboard heaters. Most grow shops carry them.

You will also need a dehumidifier and an AC that can be in the "on" position upon receiving power. Believe it or not most of the cheaper ones without the fancy settings will do this. When running an AC's will also work as dehumidifier.

Wire the AC up to the thermostat so it comes on when warm, and wire the dehumidifier to come on when it is cold. Set it and forget it at about 78.

Both of my non light circuts have secondary SPDT thermostat controlled plug in outlets, one for warm and one for cold. It may take some research if you dont know much about wiring, but you wont regret it.

my controller has setable outlets for a de-humid, and a vent fan or a/c
the portable a/c i own is the digital type, so its not gonna work automated.
not once has the room ever gone over 90, what is the dead-line on temp....?

I'm not sure about indoors. This summer my girls had to deal with days of 105+.

If your plants are healthy and the root system can handle the demand there should be no problems.

I hear that with the added co2, the girls can handle more heat too.

My only concern would be the humidity during flowering. Gotta keep the humidity under control.

Sounds like you have a great setup. Don't stress about it. Keep an eye on them and have fun.

Absolutely. that's what it's about.

Having the basics down, doing them well and consistantly, Has been, is now and will always be the key to success and enjoyment IMHO!

Cant see that picture your talking about.

90 Degrees is almost instant death to an indoor plant..Adds a ton of stress..A/C unit im thinking will cure you problems..But i understand the whole $$ thing..
I keep my room at a constant 70-75...

LOL <min char limit>

DAY 1 (BLOOM)

DAY 7 (BLOOM) TRIM SUPER LARGE WATER LEAFS

DAY 14 (BLOOM) TRIM MED. WATER LEAFS

DAY 14 (BLLOM) CLOSE-UP OF TOPS....

Hope these pics work out better....
Ive never hit 90f in my room yet, but ive seem a few days of 86-88f
im hooking up a vent fan ran by my enviromental controler, to see if that helps with heat and humidity
if not, its on to the a/c unit.....
