Gary Payton

Michael ClintMarch 27, 2024

I’ve been growing weed for 30+ years, and to be honest, it’s quite difficult to surprise me. After a few decades of facing different strains, changing growing conditions, and solving whatever problem you could possibly think of, by then, I believe I’ve seen it all in cannabis growing.

Gary Payton defied every single one of my expectations.
The plant thrived, growing to an impressive 6 feet in what seemed like a blink of an eye. It quickly filled out with buds and displayed better smell each day, showing solid proof of superior genetics. The buds were tight, aromatic, and a source of immense pride, surpassing the outcome of many of my previous endeavors.

Hypno Seeds with their Gary Payton strain has won my complete admiration and loyalty. Outstanding genetics in this plant have truly turned what I always thought of to be an experiment with negligible expectations into one of the most satisfying grows of my long career.

Looking forward, my excitement for the next growing season is unparalleled. I can’t wait to see how much I can take these strains, especially with the attention that Gary Payton really does deserve right from the start.

Blackberry Kush

WhildGreeneryMarch 28, 2024

Starting my latest grow, I decided to try out some Blackberry Kush from Hypno… I planted her on a whim alongside my other favorites. Hypno Seeds said it had to be a powerful plant with rich, fruity scents… Seeing is believing. She developed purplish hues and dense resin coated buds and quickly took center stage in my garden and produced much more than expected. The buds are tightly packed, literally bursting with the heady aroma. The yield? Very impressive for her conditions…
