Okay so here is background info and problem:
Background: I am growing in a grow box i designed using 2 home depot cardboard boxes. The dimensions on my box is roughly 18 inch by 18 inch and maybe 2 1/2 ft tall. Currently i have a 100w HPS in the box but before i had 6x 23 watt CFL Both of these were creating a heat issue. For ventilation i have 2x booster 4inch inline fans i bought from home depot. They should have more then enough CFM to get rid of the heat but im having problems... I also have 1 computer fan for an intake.
Questions: I have mylar on the inside of the box. Now my thermometer says its about 90 degrees but when i feel inside the box it certainly doesnt feel that hot. Is it possible the mylar is reflecting heat rays at the thermometer giving it an unnacurate rating? Slash is the myler creating more heat? My plants seem to be growing fine but you can judge for yourself il put some pics up of the whole setup cause i hate when people dont provide good visual images for solving problems. If anyone has any thoughts please let me know. Also stealth is a high priority, i used to have carbon scrubbers on the vents/ black panty hose to get rid of light but it was getting to hot so i took it down.
Additionally: The box is in a closet that is closed so it does get hot in the closet after a while, i try and open up the closet when i can get fresh air. Possibly its getting hot because not enough fresh air is being vented into the closet?? Just some thoughts iv had...
