They put these healthy seedlings outdoors for a few hours a day in the full sun. Some growers have reported growing seedlings indoors where they had 18 hours of HID or LED lighting a day. Even cannabis plants that grow under HID lighting don’t find it easy to transition to the sun’s light.

It depends on the type of strain, current weather conditions outside, and how warm the indoor growing climate was.Īlso, many growers fail to understand that sunlight’s intensity dramatically exceeds that of an artificial light source. The good news is that two weeks is usually a long enough period to ensure your seeds are toughened up sufficiently. This enables them to survive cold nights, gusts of wind, and droughts. Plants cultivated outdoors generally grow more slowly but have more durable stems and leaves. It now needs a waxy leaf cuticle to keep water loss to a minimum. Now, the plant must keep itself protected from direct sunlight and strong winds. Once you plant a young seedling outdoors, everything changes. Seedlings not fully exposed to the sun’s UV rays also develop larger leaves than their outdoor counterparts. They also have longer stems and more fragile leaves. The overall result is faster-growing plants with long, thin cells. Such seedlings are not exposed to sunlight or excessive wind. Seedlings grown indoors and in greenhouses don’t fully develop waxy cuticles that protect lower and upper leaf surfaces from drying out. Why Is It So Important to Harden off Seedlings? In this guide, we offer three different hardening off methods. This process is called ‘hardening off.’ You need to complete it gradually to give your seedlings the chance to get used to their strange new environment. It doesn’t take much for plants to lose their moisture rapidly.Īs a result, it is necessary to toughen up your marijuana seedlings before bringing them outside. There is likely lower humidity and higher winds. You generally plant your marijuana seedlings at a time when the temperature remains unpredictable. Plants that grow outside face a different challenge. Your seedlings get the right amount of light, water, and nutrients because you set it all up. Remember, in an indoor setting everything is perfectly regulated. Plants that aren’t adequately prepared for the transition don’t perform as well as those that are. However, if you suddenly take your pampered seedlings and place them into colder soil, you could send them into shock.

Some gardeners like to grow the seedlings indoors or in a greenhouse before planting them outside. At the end of it all, you are generally rewarded with a bountiful harvest of potent buds. Your primary goals are to keep pests and trespassers at bay and check for infections or infestations. With nutrient-rich soil already in the ground and rainfall, there is no need to feed and water the plants.

If you have the private land, and the climate, you don’t need to do much in terms of maintenance. For many growers, outdoor cultivation remains the real ‘gold standard.’ The seedlings will emerge in 2-4 weeks.If you plan to grow cannabis outdoors, suddenly transplanting your indoor-nurtured seedlings into colder soil could damage their chances of survival. Water the seeds every day so the soil doesn't dry out. Set up a grow light over the seeds and leave it on at all times. Water the soil thoroughly and place the pots or tray in a spot that's always 75☏ (24☌) or warmer. Place the sprouted seeds vertically in the holes and fill the holes with potting soil. Then, use a pencil to poke 1 inch (2.5 cm) holes in the soil. Press the soil down lightly, leaving some air in it. When they do, fill pots or a growing tray 3/4 of the way with loose potting soil that has a pH between 5.8 and 6.3. Keep the seeds in a spot that remains between 70-80☏ (21-27☌), and spray the paper towels with water whenever they start to dry out. Cover the seeds with another damp paper towel. Then, place the seeds on a damp paper towel on a plate with 1 inch (2.5 cm) of space between each seed. To plant cannabis seeds indoors, first soak the seeds in lukewarm tap water for 12 hours.
