  • Good day sir ..
    Couple yrs back you posted a dryer box you had made ..and pretty impressive .
    How well did it work is what I'm looking to find out for I'm in unfriendly state and wife didn't want to smell up the house and it looked as if you had all the bases covered just my concern was how well the carbon filter did and the drying time etc ..if I could get any info would be great .ive looked into the herb dryer reviews and all looked nice but just not enough space and pricey ..well anyways just looking to see how well it performed for you..thank you for your time

    Great day & thanks! :thanks: If you read that full thread, the discussion came up a few times. I really call it "Odor Control" and not "Odor Elimination". Depending on the strain/terps, it didn't smell up the house but I could detect it in the room the box was in. Drying times will vary based on climate and I personally found that, for the buds to NOT dry too quickly, I seldom ran the exhaust fan which also forced less of the air through the carbon filter. :goodluck:
    Hey, Mr Krip, here's a good pic of what I'm pretty sure of an early phosphorous deficiency, thought you might like to update the "Cannabis Plant and Pest Problem Solver - Pictorial" which I've found very useful.
    Did you know that nutrients can go bad? I didn't :oops:. Apparently after 2 or 3 years they start to form salts and cause a lockout. Hope somebody can benefit from my misfortune.
    Would a intake diameter of 4" and exhaust diameter of 6" be sufficient to create negative pressure ?Thanks in advance.

    Thanks for responce,newbie on a learning curve.Forgot to mention it's for a 4x4 tent.Am I right that the cfm exhaust should be 2 or 3 times the intake? Thanks again

    You typically only need an exhaust fan. The intakes can be passive. If you really need an active intake (i.e. to better control temps), 2x-3x or MORE depending on how quick you need to pump the air in. There are a bunch of factors involved. You want to be able to replace all the air in your tent every 3 minutes. So you need to take the volume of your grow tent and divide that by three. You then need to oversize the fan another 20% for the carbon scrubber and more for any bends in the ducting. You'd then need to oversize that for the CFM's of any intake fan. Again, my guess would be you won't need a fan for the intake unless your tent is in extreme heat or extreme cold where you may need to actually pump cold or hot air into the room. Usually, exhausting the heat out and bringing in cool air from the room through a passive intake works fine. :goodluck:
