Start cannabis seeds directly in clean, well-draining potting soil - and ideally in a greenhouse for outdoor production. Do not reuse old potting soil for seed starting. We discourage pre-soaking seeds or wet paper towel drenches prior to planting. These methods may work for some, they cause issues for others. We do not recommend using soil-less mediums such as peat pods or rockwool cubes.

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. Do not plant seeds too deep as they will struggle to break the surface.

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. Heat mat's may also cause issues drying out soil too quickly, starting in a warm environment is ideal.

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. Solo cups or 4x4 pots are also an excellent choice.

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 start with a liquid fish emulsion at a half dose.

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. Do not use CFL lights to start seeds.
