bugs

yoo im going to be growing a plant or two in a grow tent in a couple weeks. how worried should i be about bugs killing my plants? and what precautions can i take to avoid them from coming anywhere near my precious plants?
thanks

Screen your intake fan for most insects, durring the summer it will be hot. Spidermites are what you want to watch out for.
Neem oil is a good deterent. keep plenty of air moving around in there to keep them healthy, remove any dead leaf you see.
