how to scuff marijuana seeds

Jorge Cervantes shares his process for germinating cannabis seeds into healthy sprouts.

2) Remove seeds from the water. Pour water out onto two paper (or cloth) towels on a dinner plate. Fold the towels over the seeds to cover them.

Other Tips for Germinating Cannabis Seeds

6) In a few days, seeds will sprout. Once the germinating cannabis seeds have sprouted and each seed’s white rootlet is visible, use tweezers to carefully pick up the fragile, germinated seeds and plant them. Do not wait for the white rootlets to grow more than 0.25 inches (1 cm) before planting, or growth could slow. Plant each germinated seed with the white root tip pointing downward. Take care not to expose the tender rootlet to prolonged light and air. Cover germinated seeds with 0.25 to 0.5 inches (1-2 cm) of fine, moist planting medium.

Over and under-watering are the biggest obstacles most gardeners face when germinating seeds and growing seedlings. Keep the soil uniformly moist but not waterlogged. Do not let the growing medium’s surface dry for long. Setting root cubes or planting flats on a grate allows good drainage.

1) Soak seeds overnight in a glass of plain water. They may float on the surface at first but should sink to the bottom in a few minutes. Make sure seeds get good and wet so that water penetrates the outer shell and growth is activated. Do not let seeds soak for more than 24 hours, or they might get too wet, suffer oxygen deprivation and subsequently rot.

Thicker, harder shells or size of seeds arent an indicator of the quality.

Whatever method you choose, be it natural old school or lab coat and tweezers – do your research and be patient!

The wet paper towel method is also a tried and tested, nearly every cannabis grower is aware of – adding a simple scarify and pre-soak method is known to aid the process and aid the seeds that are slower to crack.

Just because Mason from Kentucky had 5 Lemon Kush Auto seeds pop in 3 days on a towel – doesn’t mean Liam in Dublin will have the same results with his Photoperiod Chemdawg in soil!

Covering every cannabis seed shell is also an outer protective membrane – lightly scarifying or scuffing this outer layer can help the seed absorb the critical moisture needed for successful germination.
