Hey tb, hows that freaking fogger cloner coming along? i dug mine out last night, couldn't let you be the only one playing with the stuff, lol.. I had an idea for keeping the heat out of the root zone area, which was always my biggest gripe with the thing. I'm trying moving the heat to next to the roots, not under them like before. I'm testing it now,.. wanna see how warm it gets in the root zone area after a day, or till i see the temp stop climbing. I've got a remote RH&temp probe right where the roots would be,.. reading 99%RH - 81.2F atm,.. room temp is just a degree or two lower,.. but we'll see what it tops out at.
I made an auto-refill from an old wine bottle so the fogger never shuts off, the weight of it in the center helps all the water that bubbles from the fogger to drip back into the where the water is held. Inside i made a water proof 6" diameter column out of old plastic gallon jugs stacked two high, total height of which is about 1" below the bucket lid. Filled column with about 1.75 gallons of water, set a 6" net pot into top of column, and dropped the fogger into it. Drilled a hole in top edge of bucket to let fogger cord out, as well as run an air hose into the bottom of the column of water, it helps move the fog over the top edge. Fog falls down/fills a 3" gap between the column of warm water, and the inside bucket edge. This is where the roots would hang,.. as long as it doesn't get too warm in there.
You can't see how much the fog fills the gap in the pic, with the lid off my ceiling fan sucks it away too fast, but you get an idea what i built anyway. it fills it as full of fog as the center column, 99% on the RH meter,.. and i was thinking,.. since i can see the temp rise real slow,.. even if it does get too warm in there in time, it might work to have an exhaust fan hooked up, pump out the warm every few hours perhaps. It fills with fog pretty fast.
What's ideal root zone temp? What's too hot?... anytime ive ever tried this fog shit I've had wiltiy overly warm clippings.
EDIT: Well 2 hours later I'm up to 88F, that's 10F hotter then room temp.. man i hate how hot these suckers get,.. I'm thinking thats not ideal,.. I'm thinking a circulating water pump to remove the warm water,... cool it,.. then pump it back, might be an option. How the heck do they expect us to use these if the fog can't travel far before its useless, and the fogger head gets too hot to keep close. If they weren't so damn cool looking and efficient at making fog id sell it. I haven't used a drop from the wine bottle yet
EDIT EDIT: 4 hours later,..
Decided to go bigger,.. i filled the bucket full of water and dropped it inside a 16'x16'x19' rectangular black tote thats 1-2" taller then the bucket. So same premies, over flow from bucket fills surrounding container. Area being bigger this time temps are lower, 74F room temp, 82.4F inside root zone, down from 88, RH is still 99% though. Still higher temps then id like, but i feel like im making progress, and could actually use this for fresh clippings, maybe if i set the fogger on a timer to run only so often... not sure if this would be enough moisture for roots though,.. ill have to test what RH drops to during off time. Sure seems like a lot of water and energy to root a clone but hey, if it does it faster and hairier i guess its worth it right? lol
EDIT EDIT EDIT:....
man oh man,.. a warm 5 gallon bucket of water in a tote is insulated way too well to benefit at all from a timer shutting down the fogger,.. once the heat is built up in there, you're fucked,.. pump it out is the only option i see,.. exchange it, or run it through a chiller. Unless maybe i could insulate the warmth of the water from the root zone with a buffer or air all its own, complete with a fan to move the air in the gap... christ these things get hot!
