Aromatic, resinous strain with old-school flavours
Jack Herer is on of the most popular strains in the world having been name after the renowned cannabis & hemp activist. It has won numerous cups and awards.
By crossing this with our fast parent we aimed to retain the taste and potency of the original Jack Herer yet decrease the flowering time.
This strain will produce fast, aromatic buds covered in greasy trichomes faster than you know it, and the taste and flavour still resembles the old classic.

Early/Fast outdoor timeline
Fast / Early strains keep the photoperiod growth pattern, but they begin flowering earlier and usually finish sooner — helping outdoor growers harvest before late-season weather becomes a problem.
Stage 1
Germination / Early Start
March – April
Wait for: warmer days, lower frost risk, stable spring weather
Watch for: cold snaps, excess moisture, slow early growth
Stage 2
Seedling / Transplant
May
Wait for: steady light, mild conditions, protected early growth
Watch for: transplant stress, pests, wind exposure
Stage 3
Vegetative Growth
June – July
Wait for: long bright days, healthy expansion, strong structure
Watch for: overcrowding, nutrient issues, insect pressure
Stage 4
Flowering
From late July
Wait for: first signs of bloom, good airflow, settled conditions
Watch for: humidity, mould pressure, poor weather
Stage 5
Harvest
From early September
Wait for: ripe trichomes, dense finished flowers, harvest readiness
Watch for: cutting too early, rain, bud rot
Indoor Early/Fast timeline
Fast / Early strains are most valuable outdoors, where earlier flowering and shorter bloom times help growers harvest before poor autumn weather. Indoors, their main benefit is a faster flowering phase than photoperiod versions.

Big fan of seedsman! 2/3 seeds popped, one didn’t make it.Jack is super resilient and a very light feeder, great choice for saving money on nutes. Strong genetics clones are thriving. 10/10 will run again in the future.

All seeds germinated and grew aggressively. Some plants developed purple colors early on. Good hybrid auto.

They weren't anything special. Not the seeds fault, photo sensitive seeds are the best.
