Have you tried just drilling holes into the lid and leaving it in your grow box? I'd imagine that if you leave all the capsules exposed out in the open it would dry out a whole lot faster. I have never tried them but I have read top growers using them for a couple months.I have the ona gel I works very well however it does not last a long time. I empty a few globs of the stuff on to a tray in the 8AM and its all dried out and gone by 8pm.
