Grow box - The dimensions, given in feet, 2' x 2' x 3’ (approximate 61 cm x 61cm x 91cm) are the overall measurements. Subtract 5 cm from L x W and 2.5cm from height that is the roundabout size inside the box. If calculated for volume, 0.3 m³ or 9.3 ft³. And lined the walls with white sheeting.
Location - Top portion in the airing cupboard
Lighting -1 SonLight FLUO 200W Red - 2700K and 1 Sonlight FLUO 150W White - 6400K
Environment - Noctua, which is a processor fan- 140 mm that has Rotation Speed of 750-1200 rpm and the air flow of 41.9-64.9 cfm (I sure am hoping this will be sufficient). Stripping the wires and connecting to a Mains Adapter (12 V Max), it gives me the option of having three speed settings. Attached with duct tape and silicone the flexible 6 inch ducting went straight through the attic. One moment and let me back up, I let out a crucial part. Before placing the grow box in the grow area, I covered half the wall and ceiling (where my passive intake is located) with black sheeting, the reverse side of what's in the box. This is to protect it from light reflection the cupboard door will be cracked if not open most of the day. There is about half a metre of flexible ducting sticking through my attic floor (I will provide pictures later). To ensure no light will enter I built an inside light trap. So far so good!! And speaking of light traps, I used 2 carbon filters (the type you use an aquarium filter) to protect my passive intakes.
Installed 1 Hygrometer-Digital and 1 Digital temperature gauge. In addition, from an old Dell Computer, I removed both of the PC fans, one is 80 mm, and the other is smaller but not sure of the size.
Also, installed 1 Gang Lead inside the box and one on the outside, this will give me what I need for the electrical. This is the skinny of what has been done so far.
And pictures to prove it.
ps. I will take a short break and be back with the questions.
