Know you have a new one but I ordered your PCBs anyway as I had Pro mini laying around. Thank you for your work, I soldered one and it worked immediately. Now I'll go on with the 4 others and try to desolder led/v reg we'll see how many I fucked up this way 
You saved plants lives, know that !
Cheers.

Thanks!
My wife is known as Hitler's green thumb, so no risk of overwatering here; this node will dissolve into oblivion by normal decaying before any water ever touches it... Gonna solder the other boards tomorrow though, thanks again for all your work, it's really appreciated! Happy NY 2018
