The Stones Regular Seeds – Mr Nice Seeds | Master Kush x Haze Sativa Hybrid

The Stones regular seeds by Mr Nice Seeds represent the ultimate old-school polyhybrid, combining the dense structure of Master Kush and Skunk with the soaring cerebral energy of a pure Haze to deliver an unforgettable, incense-rich sativa experience.

Finding a true Haze hybrid that doesn't sacrifice bud density or yield can be a frustrating challenge for many growers. Most sativa-dominant strains stretch uncontrollably, take forever to flower, and end up producing airy, lightweight flowers that barely make the effort worthwhile. The Stones solves this by anchoring its wild Haze genetics with a solid Master Kush x Skunk mother. This brilliant genetic balance keeps the plants manageable, boosts the final weight, and guarantees dense, resin-coated buds bursting with classic incense and earthy aromas.

Frequently Asked Questions

Can I grow The Stones outdoors in cold climates?

It is not recommended for cold, northern climates because its 10 to 12-week flowering period pushes the harvest into late October. If you live in a region with early autumn rains and frost, you should grow it indoors or inside a climate-controlled greenhouse to prevent bud rot and ensure the flowers mature fully.

How much does The Stones stretch during flowering?

Due to its 50% Haze genetics, this strain can easily double or even triple in height once you switch the lights to 12/12. It is highly advisable to use training techniques like SCROG (Screen of Green), topping, or LST (Low Stress Training) during the vegetative stage to keep the canopy manageable indoors.

What kind of effects can I expect?

The Stones delivers a beautifully balanced high. The Master Kush and Skunk lineage provides a relaxing, grounding body sensation, while the Haze genetics launch your mind into a euphoric, uplifting, and creative state. It is an excellent choice for afternoon sessions or social gatherings.

Personal Experience of Pevgrow’s CEO (Alan)

When Shantibaba and the Mr Nice crew release a Haze hybrid, you know you are in for a treat, and The Stones is no exception. I popped a pack of these regular seeds a few years ago looking for a standout mother, and the vigor during the vegetative stage was absolutely insane. You can clearly see the Afghan and Skunk heritage in the thick stems, but once you flip them to flower, that wild Haze energy takes over.

I highly recommend putting them under a SCROG net. In my tent, I let them veg for just three weeks before flipping, and they still filled out the entire 1.20 m (3.94 ft) space perfectly. The smell in the grow room during week 8 was pure nostalgia—a heavy, church-like incense mixed with that classic, pungent Skunk funk. It’s the kind of aroma that lingers in the air long after you’ve left the room.

The high is where this strain truly shines. It doesn't give you that racy, paranoid feeling that some pure sativas do. Instead, the Master Kush anchors the experience, leaving you physically relaxed but mentally soaring. It has become one of my favorite jars to reach for when I want to listen to some classic rock on a Sunday afternoon. If you have the patience for a 10 to 12-week flowering time, The Stones will reward you with some of the most unique and satisfying buds you'll ever smoke.
