Frostberry, Lucky 13 Seeds.jpg

Frostberry (new)

Genetics: Grand Daddy Purple x Purple Prozac x Blackberry Kush

Variety: 100% Indica

Avg. Flowering Time: 8 Weeks - Late August

Yield: Heavy

Potency: High

More Information:  

All new Frostberry from Lucky 13 Seed Company is a super-early flowering pure indica strain that boasts gorgeous lavender coloured buds and an intoxicating sweet berry aroma.  Created by the mating of a mutant early flowering Grand Daddy Purple male with our exquisite Purple Prozac and a Blackberry Kush, then selected over multiple generations for only the earliest flowering phenotypes.  Begins flowering in late July for an early September finish before bad weather arrives.  The ultimate strain for northern outdoor growers looking for big yields, big potency, and a big stone.  Grows very tall and thick with little to no lateral branching.  Top early and often to spread her out and achieve maximum yield potential.  Better yet, plant many seeds or clones in a sea of green and leave un-pruned for massive trees by the end of summer.  Not recommended for outdoor growers near the equator.  Must use a 20/4 light cycle with plenty of lumens in vegetative growth to keep from flowering prematurely indoors.

Frostberry for Northern Short-Season Growers:

If you live in an area with a short growing season (anywhere in Canada for instance) then you'll appreciate how difficult it can be to find that perfect outdoor Cannabis cultivar that will ripen before that nearly overnight transition from summer to fall, and the ensuing miserably cold and damp weather that nearly always spell disaster for thick buds and heavy colas.


Autoflowers have been the obvious solution for many, but the problem with autos is that since they have a genetically pre-programmed life span that can be extremely short, they provide very little room for error. If you happen to get a stretch of damp and cold weather, or scorching heat, this will cause the plant to slow or even pause its growth rate, which will ultimately lead to small, stunted plants with very poor yields that lack potency.


This is where Frostberry comes in. A combination of genetics from a special early flowering Granddaddy Purple male combined with Blackberry Kush provide the raw materials for this unique hybrid. Where Frostberry shines is in it's ability to flower earlier than most standard photoperiod strains, resulting in a harvest window that will land right at the end of August through early September in the northern hemisphere. This puts the peak flowering window of Frostberry right dead centre in the middle of summer when this plant's metabolism is running in overdrive to bulk up those big frosty colas of berry smelling goodness. Conversely, most other photoperiod strains won't hit their flowering stride until mid-late September, and by that time (here in Canada at least) the weather is starting to turn nasty which significantly hinders the potential of these plants which are warm climate annuals.


To breed Frostberry to be resilient to the challenging climate of the north, we start by sprouting very large populations and then systematically eliminating all weak and poor performing phenotypes through heavy culling. This results in every successive generation becoming stronger and more adapted to a difficult climate.
