....Well, after plenty of guidance from Swords regarding construction and lighting, as well as advice from Tony P., I just finished a new lowland Nepenthes grow chamber...here's a pic....
The front is a storm window (approx. 36" x 48") screwed into a frame of 2x3's and reinforced with L-brackets. *The enclosure has a depth of approximately 30". *The sides are composed of white waterproof wall surround, and the bottom is 3/4" plywood that has been coated three times with polyurethane and allowed to dry until no odor was present. *The top is 1/4" plexiglass. *Lighting is as follows: *3 Lights of America 65W compact flourescents (500W equivalent each), along with 2 normal twin tube 48" shop lights placed in the front and back (not in photo). *Non-toxic waterproof caulk was used to seal up most seams. *
Not counting the lighting, the total building cost was approx. $140...and $50 of that was for the plexiglass. *I'll probably just use white plastic crates stacked in some sort of arrangement, along with white flourescent light diffuser to create tiered shelving. *Hopefully, anyone who is contemplating a similar project can take some ideas away from this. *Now comes the fun part...filling it with plants!
