Except, I don't have an exhaust fan or filter. I used my tent earlier this year from feb-april, much like you did/are doing. I used an 18/6 then 20/4 light schedule daytime natural sun, then led for rest of the 20. I had heaters when needed, & desk & floor fans. Might start two after hurricane blows through.
FFOF is great. I don't think Dr Earth is better at all, just more convenient!
Stay safe down there and get out if you have to! I've got an old buddy of mine who headed out of Miami two days ago and has just been driving north. He'll probably end up in Philly where his sister lives.
