Just thought to share with everyone my build.
-8’x10’ with 7’6” ceilings shed package. Built out of 2x4 framing and 1/2 osb sheeting. Insulation is 1” thick foam board from Home Depot. The silver lining looks like a Mylar type material and seen a few others also use. Have to see how long this thin film material will last. Silver ducting tape on all seams.
- 60amp power panel with each receptacle on its own 15amp breaker and ac on 20amp Also importantly installed a surge protector on the panel to protect the ac inverter and all electronics.
-12,000btu Perfect Air Split AC DIY package. This was a very easy system to install for someone without needing an HVAC tech as the system come pre charged.
-4x spider farmer sf2000 leds.
-Fresh air drawn from a home built intake box with a 20x25x5 furnace filter. The box has 2 4” ports for even distribution of intake air on either side of the split ac air exchanger. Currently have one 4” powered fan pushing air into shed but will be adding another as I’m seeing to much negative pressure with only the one as I have a 6” exhaust set on low. The foam walls are being pulled in a bit when the exhaust dumps.
-titan co2 regulator and rain tubing with 50lb co2 bottle. Using a Garden Controls Co2 controller. And Autopilot Co2 level Monitor/logger. Very simple system to operate and has the photosensor to shut off automatically when lights out.
-small humidifier and 6” carbon exhaust fan hooked to an inkbird humidistat to control humidity. I was trying a 70 pint consumer grade dehumidifier at first but was getting to much fluctuation in temps and humidity. This was not providing a stable environment. Temps and humidity would fluctuate min 10 Degrees F and 10% RH. I was hoping to run a sealed environment for the lights on period to conserve cO2 and only air exchange at nite as required for fresh oxygen. So for that last 10 days I’ve been venting for humidity control like every 5 min and the gauge on the 50lb co2 Bottle has not even moved! Seems like conserving the co2 is not really a concern at this point and was running 1200ppm.
- small heater hooked to Inkbird temp thermostat to heat at night.
-CE smart Wi-Fi power barr controlling all 4 led lights as the app has a simple timer/schedule built in and can control from anywhere.
-8” vivosun carbon filter & fan and two isolating wall fans for air movemeant and odour control.
Just have to just finalize and tidy up the enviro controllers wiring once I figure out what to do to stabilize the humidity without venting. Seems that I need a dehumidifier that does not have such a wide band of operation ( on off cycles)
By the way this is my first grow and plants are at 8 weeks Veg.
Any feed back is appreciated.
