No no, STORE it in the fridge, you had it right. With no lid on the bottle. it needs oxygen. BREW it room temp, and try not to fluctuate your room night and day temps too much. the reason you brew the bacteria at the same temp as your rez will be is because you want the bennies that thrive in your temps (75-78 is mr. berg suggested benny happy place, although they thrive from 75-82) to muplitply because thats where they will be going to.
I dont recall exactly why myself. I believe most AN nutrients have a reputation for triggering slime. I would save those products for your coco. You also said your coco smells. My only guess is overwatering or fish emulsions (if you use them). What is the humidity level in your room?
Even if your a newb, this is a tough problem and most who come to mr. bergs thread are right where you are... clueless. Ive been growing for over 10 years and this is the first time ive come across slime. This is one of the worst things i have ever dealt with and i have seen it all. when it comes to pests and plagues the best way to keep them at bay is having a healthy enviroment, mostly good co2 exchange and no stale air pockets in your room. everything is already in there; powdery mildew spores, pythium, etc etc. but good airflow, not too much humidity, not too much heat... no problem. But this slime.. lol.. its amazing really. No sterilizing chemical compound seems to keep it gone, the only thing that seems to work is going back to square one after this evolved cyanobacteria has shown itself in your areas watersource... nature itself. Has your smell gotten better since you added the tea?
