Bill, First thanks for such an amazing and detailed build. You have inspired me !!! You are very creative and resourceful, and yours are certainly amonst the best tanks I have seen. You knowledge and talent obvious, and your work subtle and detailed.. I have been working out a builld, and have a few questions. First Question or I guess Comment is about the Mushrooms..( I love the idea of using these and am going to as part of my build). Well being a huge fan of your Titbond 3 Method, Would'nt that work just as well as a clear coat on the rooms? I have hit mine with Clear Coat Krylon, but am thinking as an extra precaution to give a couple of coats of Titbond. What do you think? My next question has to do with your drip irrigation Rain system. I thought this was very clever by the way.. How large of a pump is needed to make it work?? I can go to the Hydroponics place and ask, but I want to hear from you after using it in this application. I do have more questions of course, but I'll start with these... Thanks again for a most creative and detailed build..
