I am totally an outdoor grower...meaning i dont know jack about recreating a suitable environment indoors. I have been devoting a great deal of thought to the endeavor.
Last time i grew in this shack, i didn't supply fresh air. My growth was halted. I watered with compost tea about every 3-4 days. Quality was great but the yield was laughable. This time, fresh air will be supplied by a 4" Vivosun 195 cfm. This intake is going to come in under my 2×2 cabinet i need to build in the corner.
This cabinet is going to have an air intake/baffle at the bottom to allow fresh air in and minimize it's light output. A door is in need. This cabinet needs to be enclosed. Due to room constrictions, no doors on flower chamber. The room itself is more like 6.5×6.5×6 and is...cozy. The passive exhaust will be on the flower side.
This room gets it's air depleted quickly. So fresh air will need to be brought in. I am needing to combat the cold of winter and the heat of summer. I have acquired a Haier 5,000 btu A/C. Its about the smallest you can get and only runs at 4.5 amps. I am acquiring one of those Econohome wall heaters that runs @600w & 3.3 amps. Those heaters have bad reviews solely due to smell. They require an airing out but should work well for the small space. How cold will the cold get? How hot will the hot get? California gets about 28° coldest where I am, to about 114°. I am going to double up the styrofoam already on the walls...and we will see. That fresh air from the outside will be the killer and i can only battle that environmental factor by running at night time during the summer and during the day during winter time. Bridges to cross...
Next trip to the hardware store is for trash cans to house my soil mixings that are hindering my full access in thr shack, and some lumber to start framing out that cabinet. As soon as that gets done, the kids can graduate rooms and my grow officially goes indoors.
There will be some rewiring of some lights and new PC fans needed for the cabinet's exhaust. This should be interesting, to say the least.
-Edit- just placed Amazon order. The fan and heater are on their way.
