Purple Punch Auto Strain Information

Purple Punch Auto serves up high levels of THC, medium quantities of CBD, and candy-like terpenes. On top of this, she produces rewarding yields in just a matter of weeks. But these desirable traits didn’t occur by chance. Quite the opposite; the skilled breeders at Royal Queen Seeds worked hard to select and cross specific parent strains to carefully craft this cultivar. They started off the process with the legendary Purple Punch, which descends from Larry OG and Granddaddy Purple. The former passed down high levels of THC and a happy and relaxed high, whereas the latter infused the progeny with purple pigments and sweet and floral terpenes. Next up, our breeders introduced Old Skunk Auto to the equation to add speedy growth and autoflowering genetics to the mix. Overall, Purple Punch Auto emerged from this cross with 75% indica genetics, 20% sativa, and 5% ruderalis.

Purple Punch Auto Characteristics

This strain provides a perfect option for growers looking to maintain stealth in their operations. Indoors, plants grow up to just 100 cm. Apply some training, however, and you’ll keep them as compact as 60 cm. If you prefer to grow outdoors, you can expect plants to peak at 120 cm without training and 80 cm when subject to LST and other techniques. Stature aside, the Purple Punch Auto marijuana strain serves up a pleasant high that soothes and relaxes the body. Expect a fast-acting effect fuelled by a THC content of 19% alongside a medium concentration of CBD, as well as sweet and fruity flavours. When it comes to looks, this strain produces gorgeous purple-green buds with hints of gold.

Purple Punch Auto Characteristics

Purple Punch Autoflower Flavour and Aroma

Purple Punch Auto tastes, above all else, extremely fruity. However, she serves up different notes than most other fruity varieties. While flavours of citrus are common in many cannabis cultivars, Purple Punch Auto offers rare tastes of grape, plum, and berries. Several compounds underpin these seldom-experienced flavours, including a handful of terpenes and esters. While fruity notes punch through her flavour profile, hints of spice, wood, pine, and lemon decorate the edges. Among the many aromatic constituents found in these buds, caryophyllene, limonene, and pinene are the most abundant. You’ll experience them every time you take a puff from a joint or bong, but they become much more apparent when vaped at lower temperatures.

Purple Punch Auto Effects

Purple Punch Autoflower certainly tastes good, but what can you expect to feel after firing up a joint or vape filled with these buds? Shortly after inhaling the smoke or vapor of this cultivar, you’ll feel a clear-headed effect come over you. For a while, you’ll feel more lucid and creative. Your thoughts will flow more effortlessly, and you’ll experience increased focus. Before long, the physical side of Purple Punch Autoflower’s high will take hold. Your muscles will melt, your eyelids will become heavy, and you’ll feel the urge to hit the couch for a while. If you’re after an amplified version of this experience, consider using these buds to make edibles for a much harder-hitting and longer-lasting effect.

Growing Purple Punch Auto

You’ve learned about Purple Punch Auto’s genetic background and know exactly what’s in store when smoking her buds. Now, you’re going to discover what to expect when growing this speedy strain. Below, we’re going to take you through every step of the cultivation experience, from seed all the way to harvest.

Germinating Purple Punch Auto

Bred with care and expertise, Purple Punch Auto seeds boast an excellent germination rate. To get them off to the fastest start possible, soak them in a glass of water for 12–24 hours to ensure they become fully saturated and activated. Then, sow them directly into 11-litre pots. Doing so will remove the need to pot on, eliminating any risk of transplant shock and stunted growth. Get ready to run your lights for 24 hours per day as soon as sprouts emerge from the soil. Not only will this accelerate growth in the early stages, but it’ll keep your seedlings stout and strong and prevent legginess.

Purple Punch Auto Strain Review

Vegetative Phase

Welcome to the vegetative phase of our Purple Punch Auto strain review! Aim to maintain a temperature of around 25°C and a relative humidity of 60–70% during this stage for optimal growth. Expect your plants to grow to around 7 cm by the end of week one and around 15 cm by the end of week two. Apply training during week three to keep your plants short, or leave them untrained for large plants with a big central cola. If you want to finish your grow outdoors, now's the time to position your plants in a sunny yet sheltered spot. Make sure to defoliate at the end of veg to open up the canopy, increasing aeration and light penetration. Your Purple Punch Auto plants will stand at a height of 50–100 cm at the end of veg, depending on training techniques used, as pre-flowers start to emerge at the nodes (the point at which the branches meet the main stem).

Purple Punch Auto Strain Review

Flowering Phase & Harvest Time

And just like that, you’ve reached the flowering stage! During this period of the growing cycle, your plants will stretch up to 60–120 cm depending on training. Continue to lightly defoliate the canopy to make sure each bud is exposed to direct light. Indoors, maintain a temperature of around 25°C while lowering humidity to 40% or less to reduce the risk of mould developing on flowers. Flush your growing medium during the final two weeks to improve the flavour of your harvest. 

To harvest your buds, simply cut each plant at the base just above the soil. Hang them upside down in your grow tent with the lights off and the fans running. Within 7–10 days, the branches will become cracker dry—a surefire sign to move onto the next stage of processing. Now, trim your flowers (setting the sugar leaves aside to make hash). Then, place your buds into curing jars for the next six weeks to perfect their flavour.
