Purple Punch by Big Head Seeds

Purple Punch seeds: Grandaddy Purple and Larry OG in a feminized strain from Big Head Seeds

Big Head Seeds, a British breeder, tells the Purple Punch recipe as if it were a cocktail: two parts Grandaddy Purple and one part Larry OG, mixed lovingly and served "covered in frosted ice", a nod to its coat of resin. On the spec sheet the genetics read Grandaddy Purple BX × Larry OG. BX means backcross (crossing a hybrid back to one of its parents to lock in its traits), and here it strengthens the weight of Grandaddy Purple. The result is an indica-dominant hybrid (compact plants from mountain regions with a more body-centred effect) in feminized seeds (they only grow female plants, the ones that produce buds). The breeder calls it a "bucket list plant", one you should grow at least once. At oaseeds we like it because you know what you are getting: a bold fruity aroma, high potency and a medium-length flowering.

Flavour, aroma and effect of Purple Punch

Big Head Seeds describes a blueberry and grape aroma, and a taste that is sweet and tart at the same time, like a fruit punch, which is exactly what its name suggests. It is a strain for growers who think about flavour first and want a fruity profile that is easy to recognise.

With 20–24% THC (the compound behind the psychoactive effect), the breeder defines its effect as "cerebrally functioning sedation": cerebral, sedative and relaxed all at once. Push it further and it can leave you on the couch, but Big Head Seeds presents it as a nuanced strain whose layers reveal themselves little by little. If you have little experience, take it slowly.

How to grow Purple Punch indoors and outdoors

Big Head Seeds gives a flowering time (the phase when the plant stops growing and builds its buds) of 8 to 9 weeks. That is a medium length for a feminized photoperiod plant (one that starts flowering when daylight drops to about 12 hours a day).

Indoors, that means switching the light cycle to 12 hours on and 12 off once the plant reaches the size you want, then counting about 8–9 weeks to harvest. If your headroom is tight, flip to flowering earlier to keep the final size under control.

Outdoors, as a photoperiod plant, it flowers when days shorten in late summer. With 8–9 weeks of flowering, you want a climate with a dry, mild autumn so the buds finish without humidity problems. Its blueberry and grape profile shines brighter if you take care of the finish: a slow dry and a cure (storing the dried buds in closed jars for a few weeks) to refine aroma and flavour.
