vaportek optimum 4000 is what i own. works great.. realistically the high output cartridges should be replaced every 75 days. I toggle my settings from 5-8 on average. The high output cartridges are around $70. Can get expensive but worth it, especially when you got a room/house full of drying bud and trim time. I recommend using a carbon filter on the grow and use the vaportek inside the home, on the outside of grow. Works great and like i said it's especially useful once drying/trimming.
You can just use the 4000 without a carbon filter on most strains but for added security i still recommend a carbon filter if you vent your grow outside. In a sealed room there would be no need for a carbon filter and the 4000 would take care of the smell perfectly.
anyone try to refill the pouches with essential oils that are in the plastic strip when they are spent? can it be done?
Ive heard of folks recharging the cartridges with ona liquid concentrate with some success
no clue but ona is completely different from the natural oils vaportek uses.
any idea hows it done? would the backing have to be peeled apart? anyone want to chime in on it with some pics? a mini tutorial? cant be tha hard just keeping the integrity of the orginal package the oils came in without damage
