Named after the legendary cannabis activist, this sativa-dominant hybrid offers a balanced high that combines cerebral stimulation with a gentle body relaxation. If you're planning to grow Jack Herer https://thejackhererseeds.com understanding its growth timeline from seed to bud is essential for a successful harvest. In this post, we’ll walk through each stage of the Jack Herer growth cycle, offering insights and tips along the way.

Germination Stage (1 to 7 days)

The journey begins with germination. This is when the seed cracks open and the taproot begins to emerge. Most growers use the paper towel method or place seeds directly in a starter medium like peat pellets. Jack Herer seeds typically germinate within 24 to 72 hours, but it can take up to a week in some cases. Keep the environment warm and moist, ideally around 70 to 80°F (21 to 27°C).

Seedling Stage (1 to 2 weeks)

Once the seedling breaks through the soil, it enters the seedling stage. During this time, the plant develops its first true leaves and begins to photosynthesize. Jack Herer seedlings are relatively hardy, but they still require gentle care. Use a low-intensity light source and avoid overwatering. The seedling stage usually lasts about 10 to 14 days.

Vegetative Stage (3 to 5 weeks)

After the seedling stage, Jack Herer enters the vegetative phase. This is when the plant focuses on growing leaves, stems, and roots. The plant will need more light—ideally 18 hours a day—and a steady supply of nitrogen-rich nutrients. Jack Herer tends to stretch during this stage, so training techniques like topping or low-stress training (LST) can help manage height and encourage bushier growth. The vegetative stage typically lasts between 3 to 5 weeks, depending on your grow setup and desired plant size.

Flowering Stage (8 to 10 weeks)

The flowering stage is where Jack Herer truly shines. Once the light cycle is switched to 12 hours of light and 12 hours of darkness, the plant begins to develop buds. Jack Herer has a flowering time of around 8 to 10 weeks, though some phenotypes may take a bit longer. During this period, the plant will stretch again and start producing resinous, aromatic flowers. Nutrient needs shift toward phosphorus and potassium, and humidity should be reduced to prevent mold.

Harvest Time

You’ll know Jack Herer is ready to harvest when the trichomes turn from clear to milky white with some amber. This usually happens around week 8 to 10 of flowering. Use a magnifying glass or jeweler’s loupe to inspect the trichomes closely. Harvesting at the right time ensures the best balance of potency and flavor.

Drying and Curing (2 to 4 weeks)

After harvest, the buds need to be dried and cured properly. Hang the branches upside down in a dark, well-ventilated space with temperatures around 60 to 70°F (15 to 21°C) and humidity between 50 to 60%. Drying usually takes about 7 to 10 days. Once the buds feel dry to the touch and the stems snap rather than bend, it’s time to cure them in airtight jars. Open the jars daily for the first week to release moisture, then less frequently over the next few weeks. Curing improves flavor, aroma, and overall smoothness.

Total Time from Seed to Bud

From the moment you germinate your Jack Herer seeds to the time you’re enjoying the final cured product, the entire process takes about 14 to 18 weeks. This includes:

- 1 week for germination
- 2 weeks for seedling
- 4 weeks for vegetative growth
- 9 weeks for flowering
- 2 weeks for drying and curing (minimum)
