Hi Fellow Growers!
Long time lurker, just started my account a few days ago, and I’m jumping in with both feet! (I hope this is going into the right spot.) This first post will be an introduction to put a little more meat on the bone from my introduction in the community area. I’ll start with my grow room set-up:
My goal was to set up as stealthy and efficient a grow room as possible.
Step one was the installation of a super quiet (0.5 Sones), high-efficiency (20 watts) bathroom exhaust fan in the ceiling of a closet that leads from my home office to my attic. The fan moves 50 CFM, and is designed to run continuously, almost silently, for years on end. I can barely hear it running when the closet door is open; when the door is closed, it’s silent. The fan is wired to a light switch in my office, which also operates an overhead compact fluorescent in the closet. I installed a pull switch at the light fixture, so that can be turned on or off separately, should I need additional/temporary illumination.
The closet measures a little more than three feet deep, six foot wide, and 8 foot tall, so the fan (rated for a 45 sq. ft. bathroom) does a good job of bringing in fresh air. It flows directly out through a very short (~2’) length of 4" insulated drier vent through the attic, to a boxed off corner of the eaves, which in my home are vented to the outdoors. My yard is big enough, and my house is on a hill, and has 10’ ceilings downstairs. So, even though I live in suburbia, the delightful fragrance of fresh growing weed is ~usually~ difficult for my neighbors to detect. Visitors were oblivious to it last year, anyway.
Fresh (temperature/humidity conditioned) air comes into the grow room through an eight-inch vent I installed near floor-level, in the wall between my office and the closet. This vent also allows access for the 6’, heavy duty extension cord that connects the lights, fan, thermostat, and heater from an outlet in my office. The vent (and outlet) is hidden behind a file cabinet in my office. The interior of the vent is painted non-reflective black, and I slung a black stocking around it, where it enters the closet, to help keep light from escaping, and to keep out unwanted debris/pests. I also stapled a few strips of thick fabric along the bottom of the door, to block light from escaping into my office.
Because the “grow room” has a door that leads to my attic, I took extra measures to insulate it from temperature swings. I fit an insulating blanket from Harbor Freight in the staircase. It hangs from a hinged fencepost that opens and closes securely, to eliminate freezing or sweltering temperatures from reaching the interior door. It works great! (…Should have thought of that long ago, just for the savings on heating and air conditioning.) Space blankets line the walls and floor, primarily for reflecting light, but they may help stabilize the temperature too.
The “gear” in my grow room consists of the following:
A Viparspectra XS1500 (Amazon.com), along with a few “blurple” light strips, to help with root and bloom development. The Viparspectra is a full spectrum light, but I figured it couldn’t hurt to add a bit more blue and red spectrum – and my wife’s african violets haven’t missed 'em.
When the temperature drops, I use an Inkbird ITC306T thermostat outlet, for managing the smallest electric oil heater I could find – a “Comfort Zone CZ7007J” which offers three heat settings {500W, 700W, 1200W}. It kept the grow room in the upper 70s during the days, and in the low 60s at night, right through the cold of January.
I run an oscillating 10" fan on the low speed, and have it connected to a timer that turns it on and off throughout the day. For humidity management, I have a dehumidifier I can run from my office, but there seems to be no need to reduce humidity. I add humidity (during the winter) the old-school way: A wet towel draped over a converted metal shelf, fit into a basin partially filled with water, with the fan blowing over it. This simple device kept my growing/drying room at or below 60% humidity without the need for anything more complicated.
That’s it for now. Next post will be about the soil, seeds, and amendments I’m using. Please let me know if I’ve passed over anything you’d like to read more about.
Your friendly, closeted farmer,
