Ok thanks dude, my auto is 3 week old and iv put it straight into tent along side my photoP that has just changed to 12/12, along as it will be fine im happy even if it means slightly less yield from my auto
Other than size and progress, they flower when they are a "certain age" not because of light cycle. Just finished some Northern Lights and 1 ended up much better yield because the other pair had a rough start.
I'm probably going to do more soon along the photo periods...
