Be interesting to see how @Olderfart setup works! Looks like a much improved version of what i do in my lil 2x4 since appears to be sealed up! I just have a small clothes drying rack in mine tho! I do use inkbird controllers and a humidifier and dehumidifier/small extraction fan in it to hold the rh where i want it during dry process but don’t think its any kinda replacement for the cannatrol! I wish it was cuz i am a poor mofo but also i am down with the diy if a nice homemade replacement can be achieved! I apparently don’t have the wood shop be has so if his works i would have to find me some kinda secondhand option i could repurpose!

An old fridge would work perfectly, all you would have to do is add more shelves and fans. I am pretty sure that the shelves themselves could be that three layer appliance box cardboard, it is likely strong enough, and since it would be slightly absorbent, lack of holes many not matter that much. You could even put holes in it to help with that - more work, but not more money. I am not sure, but I suspect that the only fans needed are salvaged computer fans, even for air extraction. If using them for extraction, you could use two, one on the outlet, and one on the inlet which might ensure that you move enough air early in the dry. I am pretty sure that with less than $200 and an old fridge, I could make a unit that would process a hell of a lot more bud than my version will. The air circulation would not be as fancy, but I suspect that I have gone overkill on that aspect - as the bud reaches the final target dryness, the need for vigorous air movement declines enormously. And as long as whatever air movement in there prevents mold from starting anywhere in the load of bud early in the dry, otherwise large variations in the RH seen early in the dry among the loaded bud will not matter.

In any case, if you have the room, and more time than money, setting up a salvaged fridge to do this is feasible. The largest expense is a humidity controller. I use the Inkbird that does both temperature and humidity, but if you could find a cheaper one that does RH alone, that could work fine if you just let the unit work at room temperature. If it were not for the hassle of obtaining and moving a fridge, that is the way I would have done this project. By comparison, my unit weighs maybe ten pounds, I could pick it up with one hand to move it to storage if it had a handle. Perhaps I will install one.

In other news i noticed i had a bunch of reward coins for the ihop app that u can exchange for free food! Haven’t ordered from there in forever and last couple times was using the rewards for free grub so wasn’t sure how i still had some! Ordered me a free biscuit sandwich combo and realized u still earn the reward coins even when you get the food for free so its like a never ending refill system!

I use separate rh and temp inkbird controllers on both tents! I got those vs the combo cuz each controller has a plug for high and low side for being able to turn on humidifiers and extraction fans and heaters and intake fans to try and keep everything right in preferred range!

Where’s @Badfinger hiding??

Since he’s an eagles fan if I remember correctly!

Yummy!

Canntrol uses dew point not relative humidity

RH control = Dewpoint control. You can't stabilize one without stabilizing the other. It is no coincidence that the display on the Cannatrol includes RH as well as dewpoint, the two are dependent.

I am not trying to criticise Cannatrol here, they have brought food science to the table, and they deserve credit for that, especially for doing it by bringing an effective and currently unique product to the market to allow home growers to use that food science. It it totally understandable that they do their best to present their product as distinctive, which at this point it certainly is. However, it is not distinctive due to how it measures water. It is distinctive because it is currently to my knowledge the only home grower sized device that accurately controls relative humidity during the dry and cure process. You can describe the means of that RH control with whatever terms you wish, but I guarantee you that the sensors involved do not have much to do with our concepts of water in air. If we were to really get close to the metal on this, you would have to be describing the target measurement in some bizzarre terminology identifying the electrical response of some substance used in the digital sensor(s). If you dug deeply enough into the physics involved the terms used would be completely unintelligible to anyone but a physicist. For us amateurs, dewpoint or RH will work better, but the two are equivalent as far as decision making is concerned.

The other aspect of this that I need to mention before shutting up is that although the price of the Cannatrol seems excessive, a person needs to understand that setting up to manufacture a device like this from scratch is really costly, and the target market in this case is tiny. Of course these things could be made a lot cheaper, and maybe at some point they will, but the small size of the market makes it really difficult for a company to make a buck bringing this kind of brand new product to market.

Were it not for Cannatrol's device, their descriptions of it, and the stellar results, I might not have taken my drying mischief this far. So I owe them for the inspiration to dig a bit deeper. But I'm betting that I do not need to spend that kind of money to achieve the same end and I am pretty sure the job can be done for even less money than I have spent.

RH control = Dewpoint control.

RH control = Dewpoint control. You can't stabilize one without stabilizing the other. It is no coincidence that the display on the Cannatrol reads in RH, not dewpoint, not vapor pressure, not water activity, etc.

From the way I understood it temp and dew point = RH and the pictures I've seen of the controllers on the units the display reads temp and dew point.

I'm sure your unit will work great not trying to knock it you do nice work. I just thought it should be mentioned since its a big part of what makes Cannatrol

I assume the readout on it displays rh cuz its easier for the consumer to understand whats happening inside vs showing the dew point! Like I previously stated tho its outside my budget so haven’t investigated it whatsoever but like my homemade $50 bucket tumble trimmer vs a $500 premade one i am all about the diy if it achieves a close enough end product for fraction of the cost!

If it operated off dew point i figured if the unit had an internal dehumidifier then it has to set that based off the units internal temp! That way regardless of where u live and what the units temp is it can still achieve the desired result!

Yes it does but don't believe it has built in humidifier hence the need for the damp sponge. The pictures that frank posted of his an what's on their website show big read outs for temp and dew point with rh small below it

Why Relative Humidity (RH%) is NOT a Good Measure
Relative Humidity (RH%) is probably one of the most misunderstood terms we use when referring to drying and curing. RH% is made up of 2 absolute numbers: Dry Bulb and Dew Point Temperatures. This means that you can have the same RH% at 50° degrees and 80° degrees.

Think about that for a minute… by using temperature and dew point we control the Vapor Pressure… and have 100% control of the process.
