Blue fire is a F1 cross between Blue Treacle autoflower and Fire OG Kush photoperiod.
Blue Treacle is a potent cross between Blueberry and Sweet Tooth Automatic, it is known as one of the highest yielding Blueberry Auto's available.
Fire OG is known for being one of the strongest of the OG strains, The plant has frost covered nuggets with red hairs, giving the appearance that it is on fire, hence where the name Fire OG comes from.
Being a F1 the plants will be a mix of phenotypes ranging from fully automatic, to a mix of auto/reg traits. Expect these to grow larger than regular autos and take longer to finish, typically 100-120 days.
The current grow of Blue Fire started showing sex at 20 days, and it's growing taller than the mother plant did. For you outdoor growers this will give you larger yields then a regular auto without making you wait until October or later to harvest. This is a perfect combo for the grower who lives in a area with a lot of rain, or for those growing in areas with a shorter growing season.
