Ok so I've looked at quite a few of other member posts on orchidarium builds. But Im still undecided. I'd like to build a smallish tank. 28wide x 36tall x 14deep. I have a 4 bulb 2 foot long t5 fixture I will use for it. That's about the only thing I'm sure on. I have a crude drawing of what I'm trying to do so far. I'm not sure on airflow since I've never had anything like this and also entrance of tank. Should I do a double door style or sliding? Should I have the glass drilled for more airflow instead of the slits? Placement of airvents if so. I do have a 70 gallon aquarium with glass tops and lighting I could convert but I didn't want something so large..or at least right now.
