Stealth CFL File Cabinet Short Ryders

yoooo
im growing one short rider from Nirvana and currently have a total 138 watts of cfl on her. 1. 60 w blue/white cfl and 3. 26 w red/ yellow cfls. Im using a mushroom compost soil and i think its helping.
What im worrying about is heat since it gets to like 80 im my attic and i cant get hold of pc fans. Any tips or suggestions? Hows my plant?
about a week old

The way you control heat is with less light, more air movement/control or air conditioning. There are no cheap helps in temp control.

Plant looks fine, but what kind of soil is that? Did you put them straight into compost, or did you make mix and dilute that compost? Looks like I see perlite in there, so I assume you mixed it

its new plant life mushroom compost soil, i think its alright since its been growing at an alarmin rate with no evidence of nute burn.

Is it like a bagged potting soil, or does it just say mushroom compost on the side? I'm asking cuz I'm interested in getting some

If it's working with no ill effects, change nothing.

Air exchange isn't just about heat. If you aren't getting any air exchange, that plant will soon use up the co2 in the cabinet and stop growing.

lol i check on the plant twice a day and i breathe alot while near it would that help with co2?

No! You need to completely exchange the air in the cab every 5 minutes.

I cut a big gap in the top of my grow "cabinet" and let a fan blow in there and made a exhaust hole at the back, that stabled my temp. to 26'C, you must have ventilation for them to breathe fresh air. I read in some forum here that you can put icewater in a jug in there and that should cool it down, but raise your humidity, but you still won't have fresh air inside tehm, maybe for you yes since you use O2, but they need CO2, so atleast just make vent holes
