If one reads enuf answers are there. The big dif I found between the herbsnow and any food dehydrator is the racks can be open in the herbsnow dryer so the buds can stand on end. Some like it some dont after using it, many say it needs to be in a humidity controlled room.
And they are on back order until June 15.
I have also dug into dehumidifiers a bit, I dont think the DIY units using rock salt or calcium chloride would work well enuf, also the lack control. I do see an electric unit, 30 pint, around $150 (+ the gov) with good ratings.
Now my brother has a portabuilding here, my thought is to talk to him, add a dehumidifier (with drain so no pan to empty), it has AC, add a heater, a few fans, racks everydamnwhere. Set the heater to keep it 75*F and the AC to 85*F, the dehumidifier on 40%, we could dry the whole grow at one time, maybe more! So for less than $500 (as I/we already have most everything to do it) I could have a building set up for drying! Of course brother would get to use it also.
