Hey man nice to see someone else from NZ on here, I'll be growing in the far North this season. Just germed my seeds about a week ago, they are started under a compact flourescent growing light on 16/8, i was concerned also like you said about them flowering once they went outside, so went with a compromise between 18/6 like everyone says, and the real light cycle when they go out in anonther month. i've got feminised Aurora indica and Ice from nirvana, as well as some bag seeds, plus going to pick up a few clones off a mate. Im planning on digging holes the size of rubbish sacks and lining the hole with that, a few inches of scoria or gravel in the bottom, then just a mix of potting mix 50/50 with the soil that came out of the hole, sheep shit, horse shit, bit of blood and bone maybe, and a healthy dose of root blast for the transplant, oh and dont forget the water crystals, made that mistake last season. They will be watered once a week on average. Let me know what you think. Good luck Bro
