    No - I like the industrial space age look + it was less work. I have wayyyyyy too many projects. Had to keep this one manageable.
    Seems to be working better than fine.

    Interesting... have you considered sheeting the walls and painting them white?

    You are pretty much seeing the entire inside . The room is less than 8' long x 4' deep. The door is 30" wide so that gives you an idea of the scale.
    I think I will only have room in there for 4 plants once I size up to bigger Smart Pots set on the floor.

    The bare wood on the back wall is part of a hinged panel that covers a 24" wide window. Ran out of the foil to cover the entire panel as the panel was an after thought, so as you can see, I duct taped what foil I had to the ply panel.

    The window has been propped open very day for the past 2 weeks. Has been really hot and humid. Even with open window, 2 fans, and other planned
    ventilation, the day time temps have been hovering in the low to mid - 80°s F.

    It's kind of an indoor/outdoor grow room hybrid.

    Crow, that is so cool! I wish I had a set up like this. Any more pics? Maybe of the inside?

    Thanks KF. It's just a shed I built under the porch - repurposed, from lawn furniture keeper to Crow's Nest.

    Cheers - Crow

    This is an outside - through the door view of my little "cannabis cabin", aka, grow shed.

    You can see the open rafter tails and gaps in the floor boards. Both the floor and the rafter tails are screened over with 1/2" hardware cloth to keep
    out critters - mostly red squirrels and also keep them from setting up house under the building.

    I definitely will need to shade the open areas without cutting off air circulation. I have fans on but they would be of little use just pushing inside
    air around.

    Photo was taken a couple of weeks ago. Since then the 5 plants (Northern Lights) have had their 1st manifold, the lights (600 watt LEDs)
    have been lowered and the still young Northern Lights are branching out beautifully.

    They will be moved into # 7 or # 10 (haven't decided yet) Smart Pots well before turning on for flowering. That, AFTER I darken
    the room.

    I too have wondered about "complete" darkness and have read that even indication lights on equipment in grow room can throw plants off. I have taken great pains to make my grow room light proof only because that is what I have read. Not sure about your set up but I painted the inside of intake ducts flat black to help eliminate light infiltration!

    Thanks - pretty damn interesting!

    The inquiry continues...

    I don't know the answer but I sort of touched on this topic from a different direction before... I wanted to know what triggers cannabis plants at the equator to flower since the day length doesn't vary. The answer I found was that they do it when they get good and ready, kind of like an Auto, except that a plant might veg for up to 2 years before deciding to flower. The article (which I can't locate right now and cannot speak for its accuracy) went on to say that this is only true in a very narrow band and that even a couple hundred miles north and south of that band there's enough variance in the day length for the plant to have a "rhythm". It also stated that plants grown at different latitudes have developed different genetics. This makes me wonder if the plant is always trying to revert to it's "natural" (not really) state despite it's adaptation to varying day lengths, so any light it gets during a night while flowering makes it try to revert. Perhaps there's a constant state of tension and depending on brightness, duration and a particular plant's sensitivity it gets pushed past the tipping point. Just theorizing; I'd really like to know, too. I'm sure somebody somewhere knows, but I haven't found it yet.

    Helping the plants thrive is certainly what it's all about.

    Thanks - that's an option for sure BUT I still want to understand the why of it

    There's not really any side effects to just flipping the switch in my experience. However if you reduce the amount of time gradually it will have a little more stored energy before it starts flowering. I'll look into how the grow light differs from sun but someone may already know that answer.

    Yes the quality was lower but I think it was because of the high temp and humidity of outside. It produced almost double than the same size pot indoors. That strain was not high quality “highly hybridized” from a breeder. It was from outdoor grown “regular” weed endemic to the region

    Howdy Crow, I have learned that the ambient light from street lamps, porch lights, the momentary light that gets in when entering or leaving the grow room, and maybe even from passing car head lights made a difference in my grows. I have installed 'black out' curtains over the windows and placed one at the entry to the grow room to allow entry into the room without the 'flash' of light from the door opening and closing. These measures has seemed to help the plants. Now when inside the room, I can not see my hand in front of my face where as before (after a few moments) I could see some details in the room.
