Help Me Design A New Room

[Mitgrower]

whats up farmers I have a new room I'm setting up its 10.5 ft wide 32 ft long 6ft7 ceiling. I want to fully seal the room for smell so insulation and drywall on the walls and ceiling are a must for me. I'm planning om running 14k cool tube reflectors. What size ac do you guys recommend. I wanted to use a mini split. I also plan on exhausting the lights put the chimney. let me know what you guys would recommend I do. I want the building out to be smell proof. I will be flowering 72 plants off a 5 week veg.

6,7 is as tall as you can go?

 

[Mitgrower]

yea 6,7 is my ceiling height in a basement

 

[Mitgrower]

my reflectors have a 9 inch profile so I will be losing about 10 inches of height

I like it, insulate R-30, use 1/2 sheet rock. Kaulk all sheet seams with vulkem. If your planning fully air tight scrub the room with the charcoal filter. I used to run the tube reflectors there great it saves a lot on electri Bill so you can go cheaper on A/C. But remember once you start you won't stop so don't go cheap on anything especially A/C. You might consider running C02 you'll be surprised at the results you'll find.

What size ac unit would you recommend I was thinking a 36k btu mini split or 3 14k stand up units venting the hot air out the chimney

 

[Savage Henry]

Those standup portable units are trash, don't waste your money. @CannabisJohn suggests 6k btu per 1000w but you'll be able to get away with less with those cool tubes.

 

[mancdank]

If your making a sealed room without air exchange c02 is essential imo.

Really, I rock an lg 14k btu single hose portable and it f n ROCKS!!!!!. I'm in a 1800w 8x12x7 room.

 

[Savage Henry]

Good point, Demontrich, The LG ones aren't terrible, I have one in my veg room and it gets the job done for 2kw plus a t5 on all but the hottest days.

The active air ones on the other hand took a shit on me a month after the warranty was up and never really worked that well to begin with.

Thing with the hosed/portable a/cs is they're super inefficient.

 

[DemonTrich]

Active air 14k btu dual hose are a f n JOKE!!!!! Couldn't get my same 8x12x7 1800w sealed room under 75* no matter what I tried. Pile of utter garbage.

 

[Savage Henry]

Yea, I bought two of them 3 years back, they've been in my garage gathering dust for the last two. $800 down the drain. I'd put em on Craigslist if I thought it wouldn't cause me karmic damage.

 

[DemonTrich]

I sold mine back to the grow store for 150 less than what I paid. Then went back to home depot to buy another LG 14k unit.

I would invest in a dozen rolls of tuck tape (Canada) or IPG clear red sheathing tape for the seams if you want to seal it right, nothing else works like it that I have found.
The main issue to consider IMO is that without CO2 your plants are going to choke in a sealed room with no air exchange. Also if you are running sealed, I would think you would go with the mini split.

 

[DemonTrich]

I'm a huge fan of 3m hvac flex tape.

I'm a huge fan of 3m hvac flex tape.

For HVAC it is great but for sealing rooms give the sheathing tape a try. It will peel off your fingerprints and bonds much tighter for the long haul.

 

[Mitgrower]

I'm gonna use co2 I'm gonna end up doing 12k watt only so should I just go with the 3 ton mini split and call it a day

 

[Savage Henry]

I'd go with the mini split. Spend the money now so you don't have to worry about it. I just installed a 1.5 ton unit in a 3kw adjust a wing room and love it.

You may need a bit more ac tonnage for that many lights, air cooled or not. There's a metric around here somewhere for sizing ac for air cooled lights, probably in the grow room ac thread.

 

[Mitgrower]

Just talked to my hvac guy I'm going with a 4 ton air handler

Another question guys I have to build one new wall that will be insulated and dry walled do you think the concrete basement walls should be dry wall also
