Once fully matured seeds have been harvested, they can be replanted immediately, there is no need for additional wait time unless you've produced seeds from Rosette-Dwarf Fast Plants. Check out this video for harvesting tips. If your seeds are green, STOP, it is too early to harvest. The seeds inside the pod should be hard and a shade of yellow/brown.
#7 DAYS TO DIE SEEDS FAIL CRACK#
To verify plants/pods/seeds are sufficiently dry, crack open a single seed pod prior to harvest. If you harvest seeds too early (before the plant/pods/seeds have fully dried) the seeds will still be fragile and are likely to be damaged and not germinate. It is important to wait until plants and pods are fully dry before harvesting seeds, do not attempt to harvest seed from green pods.
During this drying time, the seeds undergo their final maturation.
We recommend taking plants off of water on the 20th day after your last pollination to help the mother plants and seed pods dry out. Seed pods mature about 20 days after pollination, depending on the temperature during pod development (seed pods develop more slowly in cooler temperatures temperatures that are too hot (>85F) can also be harmful). See the difference in flower development between Fast Plants grown in high and low light conditions in this timelapse video.Īlthough we recommend pollinating every day or every other day (starting as flowers open over a 3-5 day period right after flowering begins) to maximize seed production, a single pollination event done with care will result in fertilization with easy-to-observe seed pod development and seed production. But remember, Fast Plants grown in cool temperatures or with inadequate energy from light will be much slower to develop flowers than those grown in recommended growing conditions. Even just a single pollination event when a reasonable number of flowers are open can result in good seed production. So, we recommend choosing a planting date that allows enough Fast Plants growth-days for pollination to occur sometime between 15 and 21 days after planting. In addition, each flower's stigma is receptive to pollen for 2-4 days, depending on the temperature.
Fast Plants begin flowering in two weeks (in ideal growing conditions) and flowering continues for a week or more after that. Students can participate in pollinating their own plants, even if you only meet weekly. Learn more about growing healthy Fast Plants here. In contrast, young seedlings develop strong, sturdy stems when they are grown under high quality lights positioned very close to the seedlings' tops during the first two weeks after germination (position lights about 3-10cm (1-3 inches) from seedling tops). When Fast Plants seedlings emerge without sufficient light (or worse, in the dark) they develop weak, spindly stems that remain weak throughout the plant's life (even if adequate light is provided later). The light source ought to be prepared before planting, and newly planted systems are best placed under lights right after planting to ensure that emerging seedlings have energy from light available immediately. spindly stems, small leaves, little or no flowering). Growing Fast Plants in a window-sill is insufficient lighting and will result in significanly slowed growth and weak development (e.g. Fast Plants need intense light as soon as they emerge from the soil, and this light must be continuous: 24 hours every day.
