This is a crazy blend of some tremendously exotic genetics here. One of my main goals with this recombo was to bring together these two SEA (South East Asian) genetics. In the past I have seen several times when this works out extremely well, and should really highlight the severe old-world SEA in the Black SEA. There is also some South African (Durban Poison) in this hybrid, rounding out the environmental tolerances that should be present in many of these. The male breeder was full of strengths, along with being 50% Metal Haze, one of the major SEA contributors here. The other SEA is the legendary Black Forrest.

About ½ the female Black SEA plants will be extra goodness, but some of these females may also be a bit extra fussy and require some special considerations. As an example, the fussy wicked female Black Poison P1 did not handle overwatering well at all and it hits her a tad hard.

The Rundown—Hierarchy Etc.

P1 Male Breeder: KOS’ own Candyman Haze was the paternal P1 used in this recombination.  I had also meant to inbreed my Candyman Haze this run, but alas, it was not to be, and I only scored on a killer male Candyman Haze. This hybrid is Bubble & Squeak (SOG) male x Metal Haze (Dutch Flowers).

P1 Female Breeder: KOS’ own Black Poison was the maternal P1 used in this recombination. Two individual females were used. One of these females was off the chain with resin production, terpenes, and vigor. However, she is just a little bit fussy, not bad, just a little bit. The other female was your standard ass kicking Black Poison female, hearty, vigorous, very high resin production and killer acrid terpenes. Both of these females yielded well. This hybrid is Black Forrest male x Black Durban.

Growing Information

Like I said above, you will want to keep an eye on the super juicy females here. They will have some particular likes and dislikes, not unlike long IBL/heirloom types. As when growing any sativa dominant, you will want to watch your “feeding” and use a lighter touch. Most sativas react badly to even a little too much food in their soil. They are very efficient at using and storing nutrients, and they are also very good at acquiring those nutrients from the living soil.

This is a great choice for those of you a bit tired of all the Kush/Cookie types out there. Black SEA is a unique genotype indeed, and like I mentioned at the start, bringing together a couple heavy hitting SEA sativas here should really make this hybrid capable of extravagant “Hazy” things.
