AT Stains are harvested 75-90 days after planting with a CBD-THC ratio of 24:1 to 32:1 and a total maximum cannabinoid potential around 16%. Its aroma profile features sharp haze, lemon cleaner, slightly skunky and very terpinolene dominant. These seeds produce short, bushy plants with extremely high flower to shoot/leaf ratio with an average plant size: 2.5’ x 2.5’ and large, bright green, expansive terminal flowers with white pistils. We recommended planting density (field production): 10,000 to 15,000 plants/acre.
Day Neurtal (Auto-Flower)
Day neutral or auto-flower varieties initiate flowering 28-35 days following germination regardless of number of hours of uninterrupted darkness. Day neutral varieties are typically ready to harvest, on average, in 12 weeks, depending on environmental conditions and cultural practices. Due to the limited duration of vegetative growth, day neutral hemp grows smaller (2.5‘-4’ in height and 2‘-3’ in diameter) and should be planted at higher densities compared to photoperiodic (“full term”) varieties. The smaller stature of day neutral hemp lends itself to mechanized harvest and drying solutions.
- Seedling – Emergence occurs in 2-5 days. Takes approximately 5-10 days after sowing.
- Vegetative – Period of immature development prior to flower initiation and visible bud.
- Visible Bud – Occurs approximately 30 days following germinatio
- Harvest – 75 to 90 days after germination
Flower initiation and development is not affected by photoperiod (daylength) in day neutral hemp varieties. Increased daylength will provide additional time for photosynthesis and greater plant potential. Daylength is recommended at 12h-18h with a 30 DLI.
At transplant fertigate with a complete fertilizer at 100 ppm N. Approximately 5 days following germination increase to 150-200 ppm Nitrogen balanced with Potassium (1.6-2.0 mS/cm EC). After visible bud decrease N to 125-150 ppm and increase K to 175-225 ppm depending on environment and water quality. Calcium is needed for floral development. Periodically irrigate media with clear water to reduce salt content.
Plant density – Optimal plant density is dependent on bed width and weed control strategy; it is recommended to plant at a density no less than 10,000 plants per acre, which requires multiple lines when planting in beds 40” or wider.
