Starting Seeds
Three Easy Steps
We strongly recommend starting seeds directly in a well draining potting soil - and ideally in a greenhouse. We discourage soaking seeds or putting them in wet paper towels prior to planting. While these methods work for some seeds, they do not work for others. We also do not recommend soil less mediums.
We use a small stick with with a measured mark to poke 1/4" holes into the soil. Seeds are placed gently into the hole, and covered lightly with soil. We follow it up by watering in gently. Heavy watering can float the seed to the surface and we use a mister attachment to ensure seeds are not disturbed.
Keep temperatures between 70-90°F/21-31°C and keep the soil moist but not wet. Be vigilant in checking soil moisture levels. If soil becomes overly dry seedlings will die. Too much water and they will rot. We do not recommend using domes as they can cause excess moisture - which can cause seedlings to rot.
Other Factors
We use 50 and 72 cell vegetable starter trays with depths of 3” and cells between 1-2" squares. These trays hold around 4-5 quarts of soil and provide plants with enough space to grow for a few weeks before becoming root bound.
We recommend feeding plants a liquid fish emulsion after they've been above ground for about 2 weeks, or if leaves are yellowing from malnutrition. Start with half dose of what the label recommends as seedlings are delicate.
We use high intensity lights to supplement in our greenhouses. This prevents seedlings from growing spindly and weak. Low output lights, particularily indoors will cause seedlings to grow very spindly.
Autoflower Seed Starting Tips
Autoflower varieties are extremely sensitive in their early stages of life and require constant attention. They are essentially hardwired to flower when stressed.
We suggest either planting seeds in the container you intend to flower them out in or root them in an easily transferable plug. We use 50 cell trays loaded with Earth Pots (available from www.obcnw.com).
These plugs (pictured above) allow for easy plant removal and minimal transplant shock. Seeds are planted ¼” and covered lightly with soil.
Like all seed, water in gently and ensure constant moisture. Do not over-water. Keep temperatures above 68°F, and between 75-85°F for fastest germination rates.
During all hours of darkness, and when temperatures allow, we light supplement our autoflower seedlings with high intensity lights. This isn't essential but it will give starts a strong beginning and can help keep conditions warm.
The MOST IMPORTANT STEP in growing autoflowering genetics is transplanting seedlings as soon as, or before roots reach the bottoms of plugs, usually within 7 days of soil emergence.
If autoflower seedlings become even slightly root bound, plants WILL flower regardless of how young they are. Four-inch tall colas are cute but unproductive, so be vigilant about checking plug bottoms for roots!
We prefer to plant them into the field at about 2-4” in height. If plants are deprived of light, they will grow tall and spindly, and may break during transplant or in the elements.
Autoflowers are also very sensitive to their environments, and planting in cold weather or extreme heat can cause plants to go into flower prematurely. Do your best to plan your planting schedule accordingly.
