Is my base skip to the tree Farm photo's and the bio tanks. its grate way to make fuel and Oxygen as i have now put oxygen collectors all the way around the farm it gives you more then you could need during the day. but at night it tends to slow down a little but flood lights do stop this a little bit.
I am really just waiting now for the Sealer's and some sort of way of Pumping air into my base with out having the bubbles stick out the wall's,
if you would like i can show some up dated photo's with the under side of it all so you can see how it all works, as well the new oxygen system.
