Plant Gender ID Tests

The sooner you know, the better!

You already know that half of each grow is never going to produce flower you can sell. You lose half the plants, but you also lose half the time and effort, half your available space, and half the materials. Not to mention the risk of cross- pollination that male plants bring. Separating the males can either happen in the first two weeks, or it can happen 6-8 weeks after planting. Sooner is better.

The LeafWorks Seal:
Certified Feminized Seed

The development of feminized seeds has been a huge step forward for breeders and growers. But the risks that come with unverified seeds – both in terms of ruined harvests and litigation – means you must be absolutely certain that your seeds are feminized. With the Leafworks Certified Seal, your customers enjoy visible proof that you stand behind your seeds. Buy and sell with confidence and transparency.
