Ok I haven't been entirely fair, I have had a couple of stealth grows in my bedroom but thinking about expanding a little this season was soon as the frost risk is over.
It's a 1.8 X 1.8m so fairly big and plan to put it up in a garage I can get a fresh air pipe to atmosphere.
For a 1.8x1.8x2 what are you planning on running as far as lighting and plant count goes?
have you tested the garage for temperatures.
We’re quickly running into warmer weather in the U.K. and this will bring with it warmer indoor temps but with a garage having no insulation you get massive spikes in Hi and Lo temps etc.
you’ll need a plan to deal with extreme temp swings. The tent itself will not be insulated and will conduct the temperatures of the area it is situated in.
another thing is sound. Fans create a lot of noise for a none sound proofed room.
have you considered constructing an area out of boards and timber frames? That way you could insulate the frame you’re erecting to protect it from the temp swings.
Some very simple things to remember
1. intake cool air
2. Exhaust hot air away from the tent and the garage area
3. Keep bends in duct work to a minimum
4. Get the correct fan for your tent/lighting/space (not the fan the grow shop guy recommends and usually not the one included in a tent “kit” as they’re almost always too small)
5. Over spec your carbon filter (thank me later)
There are some calculations to work it all out if you’d like to post everything you plan on using and i can do the math for you no problem.
but it’s things like working out your m3/h requirements of your room, adding 20% on to that for a carbon filter, up to 15% added on for each light depending on light choice, more %’s added on for bends in duct work etc. Which then lands you with a number that’s where your fan needs to be rated.
Once you have your fan requirements then you look at carbon filter requirements after that.
if you don’t spec everything correctly the first time you’ll be chasing temperatures, and finding ways to either cool it down or heat it up and then ultimately buying something new to help.
for example My setup will work in a 1.2x1.2 tent.
400w MH/HPS with digital ballast
400w adjust a wing reflector
900m3/h Rhino Pro carbon filter
450m3/h system air RVK150A1 fan
SMSCOM temperature fan speed controller
Oscillating fan
80w tube heater
Humidifier
Dehumidifier
Temperature gauge
This I utilise in a 1.1x1.8x1.8 walk in closet as it gives me even more control over my environment.
the environment is the key to a successful grow.
