Hey everyone, just looking for advice and feedback on my grow room.

This is my third grow, The first was an outside grow that went very well. The second was 25 seeds germinated on a low end budget so i could only afford about 15-20 cfls at the time. I got 16 females out of that but due to the low light they only produced about 7-14 grams a plant...
Just moved into a new place and bought a few new upgrades

10000 btu window unit, which when set up found that the vents that blow the air also leak light. So i ran a little duct work to my grow tent to eliminate that.

4x4x8 grow tent "in picture"
3x3x6 grow tent " not in use right now"
2 400w ballest mh & hps bulbs "only one in use right now due to heat issues.
2 booster fans.

The grow seems to be going pretty good this round, using general organics go box nutes.

If i get the process down i plan on buying a 10x12 shed and convert it for a new grow room. with better ventilation.

I currently am vegging all 20-25 plants, the bigger ones are under a 400w mh with supplemental cfls and 4 led light panels.

I use the ac to keep the room at 74-79F with 55-70 humidity
During the day i turn off half the cfls in the tent to lower the temp by a few degrees. Highest temp when monitored is 84F.

Currently on 18/6 with the lights out from 12-6 due to the peak heat of the day. During the day with the lights off the fans keep the room between 74-77 during the hottest parts of the day.

Just got in our 6' carbon scrubber and the exhaust fan isnt powerful enough, the temp in the tent sky rocketed but was closely monitored and removed.

Got ONA, already notice its Awesomeness!!!

UPDATE:
Today i transplanted the 7 plants in the grow tent into there final buckets.
I went with 2 12',4 10" assorted styles,& 1 5gal grow bag.
Not really fond of the grow bags for indoor grows but didn't know when i purchased on ebay...

Gonna veg the other plants much longer, seeing that these are not feminized seeds. im going to flower the grow tent in another week or so.

Looks good man, been thinking about adding some LEDs. How do you like them vs just a mh?

Is it to late to start a scrog in the grow tent, to many plants? working on getting adjustable scrog cage built.
Once i buy some fem seeds it will come in handy anyway.

Going to try the 36 hours of dark before i start 12/12 on these 7 plants.
Starting the 36 hours dark at the end of this light cycle tomorrow afternoon.
Plant hieghts range from 12-15in tall. Aiming for 3-4ft tall plants. Still have another 10+ that are vegging.
Let you know what happens when the light come back on after i start flowering cycle.
Here are the pics preflower.

2nd day of flowering and i already notice that i cant get my humidity in the grow tent below 50%...
guess ill have to go get a dehumidifier in a week or two.

Was researching how to bring down humidity without changing my ventilation and i came across
kitty litter
silica gel
damprid

Trying to avoid putting any more power into my grow room, and heat... would kinda defeat the purpose of the window unit working if
its just cooling a heating source other than the light.

Trying the kitty litter first. So far im surprised one bag had dropped the grow tent from 55-65 down to 42-50. Im pretty happy with those results. Going to add damprid in two days to see how much farther i can get it down. i would like to maintain 30-40s without a humidifier...

Heres a pic day 3 of flowering already seeing alot more nodes springing up. Hard to tell but looks like 4 may be males another day or two before im sure.

My bulb on my Ipower 400w shps is never cool enough to touch. I wish i would have known more about lighting before i bought them.
Any suggestion on how im supposed to keep the bulb cool if there isnt a way to run an ac duct to it. Any suggestions?

my ONA BUCKET. i find when its really stinky turning the fan around works better sucking air into the bucket and blowing out the smell of ona. For some reason it works faster.

Humidity today has been out of control, Texas weather man FUCKING SUCKS!!! Well keeping it around 50% today. normally i only have trouble with humidity when the lights are off but today its been up and down with the lights on all day.

Kitty litter and damp rid cant control the fluctuation when its muggy outside.

Guess im going to have to get a dehumidifier, i just worry that it will heat up the tent more than the window unit can cool...

Ill do another round of pics on how i have the ventilation hooked up tomorrow when the lights come on, maybe someone will stumble across this with suggestions.

So before i buy a dehumidifier i decided to exhaust my grow tent differently.i had the exhaust just coming out to the room but now i have rerouted the fans.Added my scrubber but one 240cfm wasnt enough for it so i put two for exhaust with passive intake.
