NEED HELP WITH A GARAGE SETUP!!!!

[chongsbuddy]

i have a detached garage that i built a 22 foot by 4.75 foot by 7.5 foot(high) room along 1 wall.it is totally insulated.I want to run 2 1000 watt lights with an option of running a third for flowering,and i also want a 6 foot long veg room and a work room(say a 4 foot by 4 foot work area.My garage is not heated and i need to know how to set the area with a 12 foot flower area,then a 6 foot veg area and then the work area.i need a way to heat the area and keep the humidity in check.i have some money to spend.here is a crude drawing on how i want it.anyone with any suggestions?could someone suggest a set up for air exchange,heat issues etc.it gets well below zero in the winter.

ps-this is serious!

no one? i know the pic looks like a kid drew it but its the only way i could get some sort of what i wanted to show you.im kind of computer illiterate.

In winter use the heat from the lamps anb ballasts in a sealed room setup. You may have to add a propane heater to the flower room, but that'll give co2 to add flower power. Maybe add a couple vents between veg to flower rooms with an inline fan to blow heat through a light trapped series of pvc bends unless u are getting decent temps from just the lights in veg.

When its warmer weather, use a window a/c unit instead of the propane heater.

Is stealth an issue? If so, you will need to add a good carbon filter into the outlet.

I would worry about cooling rather then heating the room, unless u live in an igloo.....where are the entrance ways to the room....

 

[chongsbuddy]

there is only 1 entrance,and that is from the work area. thre floor for the room is a sub floor,it is 4 inches off the ground,insulated and vaped.that is not an issue,like i said,the issue is bringing fresh air into the room.how can you heat it before it goes into the flower room?what if i put the propane furnace in the work area and keep the furnace on all the time on low and have a passive intake from the main garage to the work area and when the intake turns on it would pull air from the main garage to the heated work area and then to the plants,do you think that would work?

What are your intake/exhaust options? Depending on ambient temps, drawing from and exhausting into the main garage will contain heat better than outside air options. If you go with interior intake and exhaust, you could use a space heater on a thermostat. If temps get too warm you could move the heater farther from the intake. Heat will probably continue to build, although at a slower rate. When cooling is needed, raise the garage door a couple inches and blow the cold air toward the intake. It's this reason I would opt for the intake to be on the garage door end of the grow area.

I'd also consider changing things up to best take advantage of cooling. IMO, your cool intake air should flow through the veg area first, (assuming your lights in veg are cooler than flower lights.) If you locate the veg area at the garage door end, you'll avoid exhausting hot air from flower directly into veg.

I'm thinking like GR8shoeBaDizzle. With two 1000 watters (and especially three) heat won't be an issue IMO. Especially with the insulation in the garage.

I grow in that exact kind of building, but I live in a milder climate. My winters are around 20*F, high of 50*F. Summers are 52-92F.

Insulate all the outside walls and ceiling FIRST. R19 or better, and sheetrock if you can. Otherwise it will be an environmental anomaly, and CO2 will pour out the various cracks. I have air cooled hoods, but never hooked them up because I usually need the heat. I do powered exhaust with some supplemental AC for hot days, but without insulation it was insane, uncontrollable. If you insulate and sheetrock you can be in control, and never have to fight a losing battle.

I exhaust out open windows with plywood coverings, and some trees in front of the windows. You can do a mini split AC for hot days, and air cool your hoods in a line out the window. I agree with Discobiscuit on using the empty room space as a temp buffer, but then you'd also need two complete ventilation/cooling systems.

CO2 generators will help you keep your room warm, but a sealed room with 2-4K watts puts out a lot of heat just from lights, so if you can do up a duct tee or wye with motorized N/C and N/O dampers, you can flip the hood exhaust in and out of the room automagically as needed.
