G13 Haze (Mr. Nice) regular

(3)

The regular G13 Haze by Mr. Nice is precisely what her name suggests - the result of crossing a G13 with a Haze. Nevil and Shantibaba did it again; they created a great variety for medicinal users. This strain is for the experienced grower and prefers to root in a bio or hydro set-up. Grown indoors you can expect a yield of 500-750g/m² after 9-11 weeks of flowering.

Mr. Nice - G13 Haze: Nevil and Shantibaba did it again

The regular G13 Haze by Mr. Nice is exactly what you think she is when you you read her name. Indeed, it is a hybrid that has been bred by pollinating a female G13 clone by a Haze. This resulted in a strain with a high value for medicinal marijuana users. G13 Haze is a new mixture of two old school varieties and is recommended for the more experienced grower. It is a potent, strong strain and can be used well in creating new poly hybrids. This is a limited edition, so grab it while it is hot. Those who already did know this is pure medicine with an intense high, served with pleasant flavor.

G13 Haze thrives particularly well in bio and hydro set-ups and although this variety is a bit less predictable, you can expect quite lush yields of 500-750g/m² if you have some experience with Sativas and their needs. The more Sativa traits a phenotype shows, the more you have to take care that the EC value is not too high. The flowering time depends on the phenotype and varies between 9-11 weeks, wherein the outdoor harvesting time in the northern hemisphere has come by November early December and between May and June in the Southern Hemisphere. Critical Haze regular keeps the haze side of this family but tightens the flowering window, handy when 9-11 weeks feels like a stretch.

Nevil, Shantibaba and a Shelf That Still Throws Males

Say you want to stop buying packs every run and keep your own mother instead. That's the job these seeds do. You pop a pack of Mr. Nice, sex the plants, cull the males or keep one for pollen, then clone the female you liked best. If that sounds like homework you didn't sign up for, our wider cannabis seeds range has feminized options like Skunk XL, which hits around 650g/m² in 7-8 weeks without a single male in the tent.

Old-School Genetics, Sold the Old-School Way

Regular Seed Means You Do the Sexing

Roughly half of what comes up will be male. You spot them in weeks 3-4 of flower and pull them, or you park one in a separate space and collect pollen for your own cross. Our own texts name Nevil and Shantibaba as the breeders behind these lines, and the Walkabout pack is literally sold as a selection to walk through until you find a keeper worth cloning. Watch out for the space cost: you need to start more plants than you'll finish, and you need to check them daily once flowering starts.

Skunk #1, NL#5, White Widow and a True Haze

Shark Shock crosses Skunk #1 with White Widow. Super Silver Haze pulls Northern Lights, an original Haze and a Skunk into one plant, and it has been collecting awards since the 90s. Mango Haze runs Northern Lights #5, Skunk and a true Haze, and the sweet mango smell off the main cola is not marketing, it fills a room. Shit is an original Skunk crossed with an ancient Afghani, the same plant other breeders later sold as Skunk #1. Ortega is NL#1 x NL#5, peppery on the nose with a fruity berry taste, and Nordle comes from the Naturals, Old School Genetics series, named after the Afghani hash they called Nordle.

Haze Stretch or Afghan Squat, Pick for Your Space

Critical Skunk finishes in 6-8 weeks and can push 650-800g/m² indoors, though outdoors its aroma travels, so choose your spot with that in mind. NL5 x Afghan stays compact and gives 500-750g/m² in 7-9 weeks. G13 x Skunk does 500-650g/m² in 7-9 weeks on a plant that barely stretches, with some phenotypes wanting a tenth week. Super Silver Haze takes 9-10 weeks, and Spice wraps in about 8 but grows tall, so SOG or ScrOG keeps it manageable. Walkabout is one for outdoor or greenhouse space, since the sativa in it gets awkward under a light.

What We'd Put in the Cart First

Building a mother room? Start with Critical Skunk. It's forgiving, fast, and easy to clone. Chasing that old coffeeshop stone, go for Shit or Medicine Man, both around 8 weeks with dense, calm-smoking buds. Shark Shock is the easy first regular if you've only grown feminized before. One thing to stay on top of across the whole shelf: the tightly packed Afghani-leaning buds on Critical Mass, NL5 x Afghan and G13 x Skunk hold moisture, so keep humidity down late in flower and get air moving through the canopy. Most people hunting the Mr. Nice seedbank come looking for Super Silver Haze, and it's still the one we'd hand a Haze fan with 10 weeks of patience.

Frequently asked questions

Are Mr Nice seeds regular or feminized?

Every Mr. Nice pack we stock is regular seed, so each pack gives you both males and females. That's what you want for breeding, making your own crosses, or picking a mother to clone. If you'd rather every plant flower, look at a feminized strain like Skunk XL instead.

Who breeds the strains on the Mr Nice seedbank shelf?

Our product texts name Nevil and Shantibaba as the breeders behind these lines, including NL5 x Afghan and the Walkabout selection. Nordle sits in their Naturals, Old School Genetics series, named after the Afghani hash they called Nordle. The parent genetics are the classics: Skunk #1, Northern Lights #5, White Widow, a true Haze and Afghani landraces.

Which Mr Nice strain is easiest for a first regular grow?

Shark Shock and Critical Skunk are the two we'd point a newer grower at. Shark Shock finishes in about 8 weeks and takes indoor or outdoor conditions well, while Critical Skunk wraps in 6-8 weeks with huge, dense buds. Dreamtime is also sold as a beginner-friendly selection of Haze, Northern Light, Skunk and Afghan genetics.

Can I order Mr Nice seeds anywhere in Europe?

Yes, we ship across Europe and further afield, packed discreetly with no clue on the outside about what's inside. Orders go out fast, and the seeds are stored properly until they leave us. Keep them cool, dark and dry at home until you're ready to germinate.
