Thanks spirit !
Anytime Miss ,could be anything except any plasticizers, i used some heating isolation foil (cheap as poss) i'll take it away when the leaves are covering the top soil to prevent dried up soil and for stable temps .
I'm still thinking about how to water , i made it like this just in case ... the thing is i'm going to run from 19:00 - 07:00 and the irrigation system i have makes a splashing sound , so if you water every day at the same time neighbours would notice the splashing and start to figure out whats up ?!? so i have to brainstorm a bit harder !
Cu soon Miss Thanks for being back again !
