Planting Your Sprouted Cannabis Seeds Outdoors

Now that your seeds have sprouted, it’s time to plant your germinated seeds. To do so, start by making a depression or hole in the soil surface about a 1/4″ to a 1/2″ deep. Place your seed in the hole with the sprout pointed down and gently pinch the soil together around and over the seed, being careful not to disrupt the seed’s placement or position. For the best results, start with high-quality cannabis seeds.

Add just enough water to settle the soil and eliminate any pockets around the seed. Take note of the weight of the watered cup—you can use this as a reference to know when to water again. This is a simple and effective way to avoid overwatering your seedlings. If you want to be 100% precise with your water quality, using a Pro 5-in-1 pH Meter is essential.

Seedling Stage: Hardening Off from Birth

Four days after placing our seeds in paper towels, we have seedlings. I place mine in full sun from day one. This prevents the seedlings from stretching and ensures tightly stacked growth. Seedlings born into sunlight develop well-structured cells that protect them from sunburn later on.

Important Note on Lighting

Rather than the traditional 18/6 cycle, it’s important to match the length of daylight hours they will face outdoors. I maintain a 15.5 hours on / 8.5 hours off cycle to prevent photoperiod plants from triggering early flowering.

Tips for Healthy Seedling Growth

• Avoid Humidity Domes: Pampering seedlings can be counterproductive for outdoor cultivation.
• Strengthen Stems: Seedlings need a breeze on them to strengthen the stem naturally.
• Soil Quality: Using a nutrient-dense living soil like Ancient Earth provides the foundation they need.

The seedlings we’re growing here are classic photoperiod varietals from the High Hopes Helios Line. These High Hopes Cannabis Seeds are equipped with epigenetic memory to handle outdoor stressors better than most. It is also advised to keep temperatures above 50°F for autoflowering seeds and feminized seeds.
