2nd Question:

Do my Plants need Ventillation to survive?
Cause once i did an Automatic deprivation , and after i went back from Holiday a week later i found every Plant dead!!!
I still dont know the Reason. only Guess: they could have grown too fast and touched the Sunheated Top, therefore rotted?

Answers:

Question:1 If you grow 18 week Sativas, they'll need less than 13 hours of light to keep them flowering.

Question 2: Without air circulation most things die.

There are weather websites where you can check daylight hours in your area.
