Barneys farm are the breeders for the pineapple express auto. I have yet to try them . I have seen people grow them though. The heat should be ok as long as they dont dry out. 20/4 is what i suggest for a light cycle.Some auto veg 2 weeks some 4 weeks, depends on strain, but most will start to autoflower within 24 days.I start a lite nute when i transplant into larger container.I do this when flowering starts to show. I start at 1/4 strength. If a plant takes 9 weeks from seed . I feed weeks 3-7. I will start a new post today with all my current stages of auto's i am growing. With 20/4 lighting .soil with good airation and moderate nutes, you should have some good results. Also watch out for pest when putting plants outside then bringing them in at night.
