Hey dude, what's up? Love your grow. You started when it gets interesting LOL.
Spider mites? Man they are endemic up here. I haven't had the pleasure yet, thank God. Hopefully you've got them this time around but I hear they are persistent buggers.
Anyways, great developing nugz. 3 weeks in lookin fine.
RE: Ozone. ok, cool if you are using for odor, but for mold I think it's kind of a pricey solution. Mold is very prevalent in this area andI had a major prob with it my first grow. Later grows I used an air cleaner and dehumidifier and that has stopped the problem.
Hey, hope you like Thailand. I speak Thai and have had some wild experiences studying and working there.
