I would say heat would be a problem. Also remeber when running an a/c there is condensation to deal with. Would hate to see you ruin the cieling of the apartment from the a/c dripping water. Next would be proper power you will need circiut for light /fan/exhaust. I suggest a/c on it own circuit with NO extension cord. The biggest issue i see is that it is an apartment.Is smell gonna be an issue? Also is this gonna be a legal grow? It is always risky when you are growing in someone else house or apartment.I have done this in the past and twice just either harvested or landlord found grow equipment and questioned me.I was actually evictedFrom a home i was renting , Because i had grow equipment set up no plants at the time thank God, but landlord did call police and they took my lights and such. I now have my own home and have no worries.or atleast alot less.
