Right then guys bit of dilema for ya! Ive been growing on my window cill for a while got a plant to a really nice size and then my brother decided to give me his 600watt HPS grow light. Ive downsized the bulb for a 400 watt son-t bulb due to room size and added a fan for circulation, however... After leaving for work for the day i returned to a 8 inch melted mess! It was completely (excuse my language) FU*KED. Now i live in rented accom so i cant really go on and drill holes everywhere... The closet its in is the perfect size if i can get it cool enough, its an airin cupboard approx 2.5 ft x 3 ft x 6 ft tall, it is fairly warm anyway and its on the top floor, in my bedroom, so i cant just leave the door open in the day cuz ppl will see it from outside and i cant leave it open at night for the same reason it will keep me awake. I cant run pipes to the windows or doors because if the landlord comes in he will see em and also my girlfriend will throw her toys out the pram cuz of the mess lol. Now my problem is how do i get the temp down and keep it down? without shelling out too much money str8 up. I bought a digital thermometer and its pushin well past 120 f, now any thick fool would realise thats ten times too much i just cant figure out a way to cool it down enough to keep it reasonable to grow a plant. If i cant suss it out ill have to revert to window growing but as you will know its startin to get cold out, and so not a lot of sunshine comes in my room (wrong side of the building) so is there anything i can do? any help will be used wisely thanks guys and i look forward to your replies.
