I've had some questions of local sources. Most tell me distilled should be neutral but I haven't found one to live up to that. I will know more when I have some ph drops/strips and get my meter tested. That could definitely be fault of equipment. I'll try to repost here once I know for sure.

I plan on keeping the pad in low 70s, or maybee spot on 70. The space for the propogation tray is 18"x18"x14". I have a high dome and a low one. I can figure something out if I need to lower a fluorescent close to the seedlings.
