ONA Block means no more carbon filters!

I found the little cans of Ona Block at a local hydroponic store a couple months ago, and for $8, it's been a great investment. I got the fresh linen version.

I used the first one in my veg room, and never smelled anything at all. At the time I left the cap wide open and after a couple weeks it was dried up pretty well, but I took a knife and got the block out of the can and cut it up into a bunch of smaller pieces. And the stuff on the inside was still fresh and I used it for another month!

Now my second grow is 34 days into flower, and I don't even have a carbon filter anymore. Just a can of Ona on the floor, with the lid upside down on top of the can and mostly closed. The oscillating fan hits it at one end of its sweep.

The stuff works! You don't smell the plants at all!

Now with my luck someone will eventualy find out that it harms the plants somehow, but for now it's the best $8 I've spent in this project so far!

Way to revive a dead thread. To anyone else that finds this, don't use Ona gel in the same room as the flowers. Your weed will be effected poorly, or so the conventional wisdom goes. Carbon filters work great.
