What's up people,

Iv been growing in tents for the longest mostly a 4x8. I now moved into a house that I bought and want to dedicate a room in the basement. The room is 13'L X 10'W and the only problem I see right now is that I have NO SPOTS TO VENTILATE. Meaning no window or anything to vent hot air out of and I didn't want to cut "holes" in the door. I want to run 4 or 5 1000 hps lights. I plan on using a good size portable ac unit and probably some co2 in there. Just need some suggestions....? I'm experienced but every situation is different especially when I don't have a spot to vent. ALSO I just had an electrician run a 250v 30amp to the room. I can run up to 6 1000 with that plug I believe but I’m not going to max it out I will leave maybe a plug for the ac unit or something and I have a couple plugs already in the room for small stuff. Will be using a powerbox light controller

Just need help on where to vent could I from that vent thats in my ceiling?

Here are a couple pics of the room

I built in a smaller sized (10'x8'') dedicated flower room but I had to frame out a false wall to partition it off from the rest of the room. To solve the same problem you have I cut 2 holes for 6" ducting to fit through. Both are powered by inline fans with speed controllers. One duct is for intake of fresh air; there is a ducted carbon filter on the inside of the room. I use no co2. The other is for exhaust; it's attached to an xl hood to pull off the heat from a 600w hps. The exhaust duct goes straight through the wall which was an eyesore and I wanted it to hidden so I screwed an old tv cabinet to the front wall and that's where the other carbon filter is.
I should add that in order to build the wall I had to use a hammer drill and lags/screws to secure the framing to the floor. Then it was an easy build after that.

What about a sealed room with a mini split?
Does the room has a exterior wall?

A mini split only needs one little 2-3” hole n it gets covered .
The CO2 will help you keep higher temps
You also need a Dehumitifer If you don’t want to vent .
Doesn’t look like there’s a drain in the room
:(

Why wouldn’t you just use PL premium for the bottom stud? It will hold and can be removed with out leaving behind holes.

Where does that vent in the ceiling lead to? Do you have central air or something?

Does that ceiling vent lead to a utility room? Does that room have a place to vent? Maybe you could intercept that line and put a booster fan if necessary and get it outside. Tough situation though. On top of that, I would hate not having a water source and a drain handy. That's a lot of lugging water and equipment around to wash it, dump waste water, etc.

Just a thought: how tall are your ceiling? Most basements are not tall enough for 1000w, and in a basement grow wouldnt you like to get the plants off the cold floor if youre growing winter time? 10x13 seems small for dealing 5000w especially if you dont want to cooltube them. Maybe led would work out? Plants under led likes higher temps than under hps. If LED is still new to you i rexomend checking out grandmasterlevel/hlg on youtube, theres finally some decent options

I see 8 feet there. The floor in the room will hold a warmer temp then the rest of the basement floor( plants like there roots a little cooler anyways)

I run 4 DE 1000s in a 6x16 room 8.5 ceilings , and a CO2 burner
Plus a ton of fans etc giving off heat.
5000w is easy to handle in there if done right.

Because screws are sturdier than glue and the wall was intended to be permanent. The exhaust fans are mounted & supported by the wall and I wanted it strong enough to hold an a/c unit. A previous owner had built some shelving that was mounted to the floor so a few of the holes were already there; I just extended it to the other wall. Foundation is made of field stone; it's an old house no concrete to screw into on one side so the bottom stud is the main support.

Iv decided I'm going to get a professional to install a mini split a/c unit in the room and be done with it. That way I can run what I want and the light will be air cooled. I plan on running 4000 watts to start off with. And I might add co2 later. Atleast my temps will be good and I have a good water source. My veg will be in a different room along with drying. Just curious whats an average yield on a size room like this?

There is a register in your ceiling. Disconnect that from your central and vent through that or cut holes.

If you can change it out do so to the max size you can fit in the space. If your lucky it goes into an empty wall and soffet and you can put a large vent tube in the area.

I bought my own split, hooked up the inside and ran the lines , mounted the unit,
Had a tech make the hookups .
