I'm sure they work but I can't imagine that they work that much better than the felt - if any better. With cost in mind they wouldn't be my choice - I can't imagine cheaper felt pots and considerable more soil working worse than a smaller air pot with much less soil (same total price). A comparison might be fun though.
Price comparison:
6 x 5g air pots: $63 ($10.50 each)
2 Happy Frog 2ft^3 (15 gal): $14 each - $28
total: $91
6 x 7g felt pot ($5.50 each): $33
3 Happy Frog 2ft^3 (15 gal): $14 each - $42
Total: $75
Yeah, you get more soil and it's still less expensive. Think 5g air pots would out perform 7g felt pots? Now just think if you made the felt pots yourself...
For the same price you might be able to do 10g felts versus 5g air pots... Think the air pots work twice as well? I dunno...
I was thinking less of the price and more which would perform better using the same amount of medium in the same litre pot , it would be just as easy to justify the cost judging from the results , plus , the initial outlay would not be much as i'd only be doing a 1 pot comparison , i always work in litres(uk thing lol) gallons confuzzle me(dnt take much),
So 2 pots , 10L, rockwool/hydroleca , same feed pattern , my result would come from extra grams grown , or not,
can i keep it this simple and get the desired result ?
After drying the grapefruit too much, there is not enough moisture in it to cure (jar at 55%RH after 24hour of being in the jar), 1 jar I put 2 small lemon peal, the other nothing. The buds truly smell like grapefruit, the bag appeal is premium in my opinion and the high is great, productive kind of high while feeling very relax... The taste is awesome, compare with the best buds I have ever smoked, too bad I fucked up the cure, still a lot tastier than the AK!! The fact that its organic makes it even more enjoyable to smoke!
I say I fucked up because apparently if you dry the buds too much before jarring, no cure will occur, it's too late, and there is no way back. I read that on Kyle Kushman webiste somewhere
