I do agree with Organoman that the heater inside the tent is not a great idea. Best to heat the air outside the tent in w/e room its in if it needs heating.
Overwatering in fabric pots or plastic can happen, all depends on your substrate, Heavy compacted mediums with bag drainage can be waterlogged no matter the pot type. Your does not looked to have much aeration so be conscious of that. Water is not something I do in ML per plant normally. I pick the pot up and if it needs water I give it, if not I wait a day. I grow with amendments so the water does not hold the nutrients so if I skip sometimes its not misfeeding them.
