Disn00fanswered grow question 3 years ago For outdoor plants you want to get the seedling off to a strong start. I suggest bringing it out for the day for a few hrs like 6-8. Then bring it indoors and supply artificial light so it has 16-18 hrs of light. This will get the seedling nice and strong also it will be hardened off.
Ideally you want around 14.5-15 hrs of daylight to put your plants outdoors for good. Best of luck with your grow.
