Perpetual grow, 1 dehumidifier?

Heya guys! Wondering if it's possible to start a perpetual grow, having only 1 dehumidifier.

My setup will consist in a 4x4 and a 2x4. Possibly also a 2x2 if needed, space is not much. All in the same room.

I was wondering about Humidity between all stages.

Is there a range I can set the dehumidifier in the room, maybe reading values from the flower tent?

Or should I use it only inside the flower tent? Might be dangerous for veg.

I'll make sure the flower tent will be the 1st point of extraction.

(There's also drying, which I'll probably use the Veg tent, and I guess at that stage I can set the same range for drying/flower)


Any thoughts? Let me know about your experience!

Get the most powerful dehumidifier you can afford and try to maintain around 50%rh the whole way through. Gods this sounds like deja vue. Good luck! Maintain the humidity for the whole room with proper ventilation things will equalize.

I have to dehumidify my sealed walk in closet especially at lights off, it’s about 5x5 to 6x6 in size so not very large but with a bit larger plants in there, the humidity spikes to maybe 55 to 60% with lights off but is about 45% with lights on without the dehumidifier on

a good dehumidifier is priceless imo as I never have had any issues with PM or botrytis yet

So I do runs start to finish in there with three oscillating fans two on the wall like in a full room and one lower on the floor pointed upward to get airflow underneath the canopy, and one dehumidifier 35 pint size as the 22 pint will fill up too fast in my area plus AC and with three tents in one room I’d say get a 35-70 pint or maybe even larger dehumidifier as way overkill is much better than under powered especially with a dehumidifier in a room with two or three tents in it…

if you can, connect a hose to the back of the dehumidifier to drip outside or something so it’ll run continuously, but if you do have to empty it manually it isn’t the end of the world, as I currently have mine filling the bucket not continuously dripping out a hose.. I check it morning and night and it never is over half way full.

Maybe i'm just day dreaming but, what if you could box out the dehumidifier (make sure to get a continuous drain w/ hose style), and duct mod it with 2 motorized dampers on a Y fitting, so that it switches the flow of dry air between 2 separate tents, and is triggered via digital humidity controller with remote sensor in one of them. Figure out some cycle (maybe even program via arduino or something) that keep both spaces at the correct RH, or even reverses the flow back and forth, etc. Make use of only having one single unit for multiple tasks.

Its kinda like adding a main coolant res to your one bigger chiller, and then using multiple pumps/coils running from that res to all your other hydroponic system reservoirs, instead of buying another chiller unit for each system, and having to spend 5X as much to do the same job..

Dang.. those dampers are spendy these days to buy new online.. I got some cheap, from a salvaged\reclaimed building supply store years ago. paid 40-50 for 2 if I remember right. Found 24 volt door bell transformers brand new for a few bucks a piece to power them with too. Not exactly sure how to rig them up for my perpetual grow system i'm working on myself, still dreaming..

Probably cheaper to buy more or bigger and better de\humidifier units, but not as efficient IMO. For example, you add a humidifier to your veg tent, you then need a bigger dehumidifier for the rest of the area. Your paying more for energy to dehumidify the humidity that your paying more for. Dumping anything into the atmosphere (or even in your house really) is a huge waste if you ask me. Even humidity should be stored somehow, into big blocks of those dessicant sillica gel packs.. or rotary wheels like inside state of the art air handling units on huge buildings. Anyway,

I like the idea of having an extra small tent, just for all the environmental equipment to sit in. You could actively duct that one tent into the other tents, so they circulate around each other in their own closed loop, so not having to condition the whole room its in. Maybe just scrub the whole room.

There are huge gains to be had when making the most of your equipment. So much energy is wasted otherwise, like the heat coming from every ones tail pipes..
