I've been growing in an open place at my appartement, and I went 4 days away. Then I came back, and when I pused the entrance door, I said my self; What smells like weed here?(I didn't even THINK my plant because it's only 9''!, can't reember weeks). Then I went closer to check it and the odor was really heavy. How can I hide it?
carbon filter, you can go ona gel but it's not as effective as carbon. it also helps to have your plant in an enclosure suck as a tent or grow box or a grow room, just something sealed so smell can't escape so you can filter it.
Check out The do it yourself ONA Bucket in the do it yourself threads .They are easy to build and makes the whole place smell like fresh laundry.
