One of the most unique aspects of our varieties are their early finishing times. If plants reach their sexual maturity by mid-July (northern hemisphere), they will be ready to harvest by mid-September. This groundbreaking advancement allows for cannabis cultivators to have crops out of the ground before inclement autumn weather hits in most areas of the country.
The beauty of it is, despite being photo sensitive, plants will react similarly regardless of your latitude. From Maine to Hawaii our genetics have shown to behave the same way. Through our research we have found that it’s not actually the daylight hours that cause the plants to flower, it’s the spectrum of light emitted by the sun as the daylight hours begin to wane in July.
Our F1 hybrid seeds are also unique in their vigor. With parents that are from two unrelated lines, the offspring grow rapidly and with incredible strength not seen in clones or polyhybrid crosses. While we recommend field planting at the beginning of June for maximum canopy, some farmers find huge success field planting in early July. Even with a few weeks in a greenhouse and a few weeks of vegetative growth in the field, yield and plant size after two months of flowering can be astounding. For later planting dates we do recommend tighter plant spacing to maximize your canopy and be prepared for slightly later finishing times.
That said, we don’t recommend planting seeds in the field prior to June 1, moving mature or almost mature specimens outside in May from a light assisted greenhouse can cause them to begin flowering immediately. With the light spectrum cast by the sun in May, it can trick plants into thinking it's fall. Pre-flowering generally greatly reduces yield and can be difficult for plants to snap out of.
For later plantings, shorter days mean lesser vegetative growth prior to flowering, and delayed flowering. Plants must first reach sexual maturity before flowering. This is generally when plants are about 1 foot tall, or 4-6 weeks after soil emergence, and depending on how happy they are in their environment. If you'r plants don't reach maturity until August they still require 8 weeks of flowering time until they are ready to harvest. This means peak maturity gets pushed well into October.
For best results sow your seeds in a greenhouse 2-4 weeks before you are ready to plant - and stick to field planting in June. Early plantings can mean pre-flowering in the field, and late plantings mean later harvest. If you are in area with favorable fall conditions - July plantings can be just fine.
