I've been wanting to buy a food dehydrator for the past few months but they seem too expensive. Didn't thought of making my own. I'll try to make one this weekend, it's doesn't look that hard. Thanks for sharing!
Can you tell me what's the name/brand of these grow beds and how did you attach the pipes? Also how can I be sure that there won't be any leaks? Did you use something to wrap around the pipes?
