hi peeps...
i wanted to ask a question regarding temperatures... ive just recently finished building my new grow box, its lit up with a 400w HPS light, and i have a 100mm extractor fan with a carbon filter fitted to it to remove the hot stale air... the fan shifts 227m3 per hour...
heres some pics of the cab im referring to.,..
this next pic here is just to show u what im doing for air intake...
i figured that the fan im using should be able to draw in air from that long hole ive cut at the bottom right??
that intake hole is like 2.5 inches wide, and it runs down the whole length of the cabinet...
i am going to be putting some material on the inside that is light proof so when they are in their dark period i will just take the flap down and velcro it shut over the air intake hole...
anyway.. this is now the second day ive had it running... when i woke this morning the temps were like 34C... and the plants really didnt look happy in there at all...
i m really not sure as to what can be done next to try and solve this problem... the temperature in the room that this cab is in is like 22C... so its not the ouside heat thats causing the box to be so hot...
i figured that a 400w light should be fine in this space, because i have seen profresionally built grow boxes that have 600w lights in them, anbd they are just slightly bigger than my box...
would having a sheet of toughened glass on the reflector make any difference??
i am planning to buy a cooltube reflector as soon as i get the money.. but thats not gonna be for like another month or so... so i thought i would see if anyone here could recommend anything that i could do in the meantime to lower these temperatures...
any help would be gladly appreciated folks...
thanx in advance...
