I have used these before, but i was very inexperienced when it came to growing back then.
Just wondering if anyone else has used them, and if they know for sure they work or not. I have read various thoughts on these, some swear by them, others say they're trash. Whats your take?
I didnt have a device to measure the levels of C02 when i used them before, and i dont want to buy them again just to see.
