When I used the LG to hatch I set it up like 10 days in advance and fiddled with it to get it right. Now I have my brand new Brinsea Mini Advance and I don't know if I should plug it in early was planning on setting eggs on Monday.
I always set up in advance. I like to watch for a couple of days to see that everything is going right. Even though I haven't hatched too much the last few years I am thinking of getting a mini advance myself. My mind always has high hopes that my body doesn't follow through with but how hard is that right?...........LOL
