K.O. Kush Feminised Seeds

Heavyweight Seeds started in mid-2008, when their team visited a local cultivator who had obtained incredible results from his latest crop. They purchased clones of his mother plants and bought them back to Spain with them.

The resulting strains created of the cross between the aforementioned mother plants was truly mid-blowing. To preserve these special phenotypes more efficiently, Heavyweight Seeds decided to create their own gene pool. It took about a year to ready their products for the market and create a brand, which has become Heavyweight Seeds.

Heavyweight Seeds put much of their focus on creating strains with incredible resin production. Their genetics produce a return in resin between 10% and 20% grown under normal conditions with generic nutrients.

Heavyweight Seeds use extreme germination methods during the breeding process. They put the seeds in places where humidity and temperature variables are adaptable, forcing them to germinate in poor conditions. They then work with the plants that have passed the first stage. This selection process guarantees that the individuals Heavyweight work with will produce seeds that can germinate anywhere.

The philosophy of Heavyweight Seeds is simple; they only breed strains with high production (flowers and resin) and strong effects. If a grower wants a product of the highest quality and bountiful crops, they needn’t look any further than the Heavyweight Seeds range.

The library of seeds that Heavyweight Seeds has created is expanding all of the time but some of their classic, original strains remain favourites with their customers. Their 2Fast 2Vast is one of the most popular auto flowering strains on the European market right now and is set to make waves in the USA soon. Regarding photoperiod strains, the delicious trio of Dream Machine, Fruit Punch and Strawberry Cake are the most popular and many customers return to Heavyweight Seeds to grab these strains in particular.
