Tagged up for this show. I think I'm going to switch my ebb n flow bucket system to a dtw coco as I get a better final product in my coco room than my bucket room.

Well Im rethinking running the mini splits for now. I think in the beginning I will run my 12x48 scrubber and 12" 1700cfm fan with and a pair of HVAC dampers. when thermostat kicks on the dampers will go from circulation in the room to exhaust outside. In combination with running my Deva lights which auto-dim to maintain temps i think I should have enough capacity to cool the room. its starting to be in the low 50-60's now at night in S. Maine. I will no longer be running a sealed room right now, I will be running vented until I design a proper efficient cooling system. I want to play around with a DIY geothermal exchanger method in the near future. maybe running a horizontal slinky 5-6 feet down on the side lot. use a few radiators/fans inside the grow room with antifreeze pumping through the slinky loops and to exchange the heat. Id like to come up with something because I dont think I will be able to run CO2 in the vent/cooled room.

So I went to Famco and had some 12" 120v Dampers made. one is Normally Open (NO) and the other is Normally Closed (NC). my 12x48 scrubber will hang near the center of the room from the ceiling. Ill attache the fan to the scrubber and past the fan Ill run a 12" "Wye" and One damper on either end of the Y connection. the NC damper will get ducted out as the room exhaust the NO damper will not be ducted and will be open in the room. My thermostat will energize (powering both dampers) when interior temps reach 81 degrees and de-energize when temps get back down to 75 degrees. this will essentially take the scrubbed air from recirculating to exhausting when the t-stat energizes. my other t-stat will be used for low temp heating. because the temps get pretty cold up here in ME, ill need to add a space heater that will keep the room warm when lights are off.

Im using 2 Auber Instruments WIFI Temp/Humidity controllers. https://www.auberins.com/index.php?ma...roducts_id=642

1 will be set for low temp/heater power on and low humidity humidifier power on
the other will be set to high temp exhaust damper power on and high Humidity Dehumidifier power on.

I also picked up a BlueLab Guardian Connect wifi monitor (how would I set the probes in a 275g reservoir? should i build a floating foam cradle to house the sensors so it raises/lowers with the water level?


I have 2 sensor push Temp/RH sensor but I will probable pick up a few more and a wifi gateway to monitor my Clone/seed tent down in the basement as well.

I should be finishing up with insulating walls this weekend. I have it all framed up and wired up now.

Fall has hit us but temps still manage to be in the high 60's low 70's here...

Bet those leaves are all gone now with that wind we had last night and today.

Nice build.

I slept right through it. It was still raining about 5am on my way in to work

[~star~crash~]

that's going to be a nice room ...good on you!

Im doing quite a bit different things this go around then im used to. im used to growing vertically in coliseums in closets down south. usually bare bulbs grows with plants scrog'd vertically around the bulb. Now i'm running a flat grow with some DE's which ive never grown with.

I also need to decide if I Scrog wall to wall manipulating the screen around the edges and middle to defoliate or clean up plants along the way... see EPIC DJM coco tree's thread:

I also don't have walk ways or isles. My canopy is wall to wall, back to front. 32 feet long by 11 feet wide. There would be no way to effectively install and use garden fence with frames for a canopy of that size, and be able to easily extract the plants from it come harvest time , plus be able to reuse the fence..I use a double layered trellis. Some strains prefer a triple layered trellis..Depending on the strain, ill put a triple layer. However, most of the time I prefer a double layer..As come flush time the colas begin to lean over, making the canopy look un even, sure, but also allows light to get down to other areas of the lower canopy for the last few weeks. It really depends on the strain though

that half pallet of DEVAs made my peepee tingle. ive got one on the way with their lighting controller. if all goes well i am gonna switch over and sell all my old stuff.
