Which Purple Punch should you grow?
Choose a Purple Punch by your ceiling and your patience.
Photoperiod or autoflower? Photoperiods give the full plant and the bigger yields, run on a timer and finish in 50–65 days, at listed THC 20–26%. Autoflowers finish on their own clock from seed, 50–80 days, at 18–26%, so strength is much the same either way. For a first grow, an auto saves you timing the flip.
Purple Punch photoperiod (feminized)
The photoperiod versions are the classic Purple Punch: you set the clock, with an 18-hour day in veg and a 12-hour day to flower, and you get sweet, resin-coated flower. Flowering is 50–65 days, with listed THC 20–26%. Heights are listed at 90–100 cm.
Purple Punch autoflower
The Purple Punch autos keep the evening character and finish on their own clock: no flip to 12/12 to time. There are 4 autos here. Seed-to-harvest times run 50–80 days. The autos are the wider spread on height, 80–150 cm, so do not assume an auto is the smaller option: read the figure. Listed THC on them runs 18–26%, right alongside the photoperiods, so they give up little strength for the convenience. Breeders keep the Granddaddy Purple and Larry OG base, and one crosses in an Auto Critical line to hold the speed. If it is your first grow and you want Purple Punch without a light schedule, begin with the autos, and check the height to match your tent.
How Purple Punch grows
Purple Punch is an indica-dominant evening strain, and most versions grow the way you would hope from that: compact and quick. Herbies' feminized is listed at 65 days and 100 cm, and Big Head's at 56 days. Barney's feminized line is listed at 50 days in flower and a compact 90 cm, with a listed 600 to 700 g/m². But do not assume every auto here is the small one. Fast Buds' and Herbies' autos are the tall ones, listed at 150 and 140 cm, so check the height on the version you are buying: the span across the family runs 80–150 cm, and type alone will not tell you which end you are getting.
Patience varies more than the character does. Barney's auto is listed at 50 days from seed, where Seedstockers' auto is a long turn at 80 days, and they say patience is the price of admission. Pick by how long you are willing to wait; the sweet, fruited Purple Punch character arrives either way.
Barney's describe branches dripping in resin. That resin is the one thing to prepare for at harvest, so keep the blades tidy and a light touch through the trim. Match the version to your patience and your ceiling, keep the trim tidy, and Purple Punch is an easy, rewarding run with a heavy, resinous finish.
Where Purple Punch comes from
Purple Punch is a named cross, and the catalogue is consistent about it: Granddaddy Purple crossed with Larry OG, two Californian powerhouses that between them give the strain its sweet fruit and its settled, indica weight. Herbies' auto extends the lineage with Big Bud and Skunk #1 folded in alongside. Breeders quote her heavily indica throughout, usually 80 to 90%, which shows in the relaxed, sleepy character growers expect from the name. Spellings and order differ from page to page, and we have left each as its breeder wrote it.
Smell, taste and effects
The effect is an evening one more often than not: reported as relaxed and euphoric at the top, happy and uplifting through the middle, tipping toward sleepy as the body settles. It is for winding down rather than getting things done, a sweet, settled smoke for the end of the day. The nose matches: sweet and fruity, with berry and spice, and apple-cinnamon on the Barney's Farm versions, the dessert end of the spectrum rather than the fuel end. None of that is a promise from us; it is what growers and breeders report.

Purple Punch FAQ
How long does Purple Punch take to flower?
Photoperiods bloom in 50–65 days once flipped to 12/12. The autoflowers are measured seed to harvest and run 50–80 days.
Is Purple Punch an indica?
Yes, heavily. Breeders quote the versions from about 80 to 90% indica, which matches the relaxed, euphoric, sleepy-leaning effect people describe. Whichever version you look at, expect an evening smoke rather than a daytime one.
How tall does Purple Punch get?
It stays contained, but the types do not line up as expected. The photoperiods are listed at 90–100 cm, while the autos run 80–150 cm. So an auto is not automatically the smaller choice.
Is there a Purple Punch autoflower?
Yes, 4 of the versions here are autoflowering. They need no light change to flower and keep the sweet, fruited character, listing 18–26% THC, right alongside the photoperiods. Seed to harvest runs 50–80 days, so read that figure, and check the height, listed at 80–150 cm.
How strong is Purple Punch?
Listed THC runs 18–26% across the versions, with the strongest listed at 26%: a figure two versions share, a photoperiod and an auto from Seedstockers. Strength is much the same whichever type you pick.
Which Purple Punch is best for a small tent?
By the figures, the shortest on this page is an auto listed at about 80 cm, but the two photoperiods with a listed height are 90 and 100 cm while the other autos run taller, to 150 cm. Sort the table by height and start from the bottom if space is tight; type alone will not tell you.
