Hello All. New here but been lurking for awhile looking at this DIY thread. Some great Ideas here. Anyway here is my DIY grow box. It's 2x3x6 feet. 3 compartments. main grow flower area is 2x3x6 mother plant area is 2x2x4.5 feet. The 3rd area is for all the electronics(timers, heat pads etc.) The mother plant area will double as a drying area until I'm brave enough to start with clones. For lights I have 2 VIPARSPECTRA V600 LED and the whole thing is lined with 2mm mylar. The exhaust fan is 4-inch carbon filter. Because this box is in my garage, I'll be insulating it for winter and installing a small 250w ceramic heater. An digital temperature controller will maintain the temperature by turning on the heater when needed or turning on the exhaust fan. The mother plant area will double as a drying area. Currently I have 3 plants on the grow. 2 Auto flower Northern Lights and one PhotoPeriod white widow. The idea is the Auto flowers should finish just as I flip to 12/12 for the photoperiod plant.
