Summarize:

This is the minimum amount of sunlight that the seeds will require to grow into seedlings. Avoid placing your greenhouse in direct sunlight or you'll risk burning the seeds. Keep your greenhouse covered with the lid in order to trap the warmth. A grow light can also provide warmth for your seedlings. Position an incandescent light at least 24 inches (61cm) away from your plants to keep them from burning. A florescent light can be placed just 6 inches (15cm) away from your greenhouse. If you see water accumulating on the surface of the pellet, stop and water a bit less next time. Be aware that each pellet may require varying amounts of water daily. You should see sprouts start to pop out of the soil after around 10 days post-planting. If the tops of the sprouts reach the lid when closed, then you'll need to start leaving the lid off. The heat generated by the lid can actually burn the sprouts and damage them. Get a single 2USgal (7.6L) planting pot for every 3 pellets. Add potting soil into each pot until it is halfway full. Then, fill up the rest of the pots with bark mulch. Dig a hole for each pellet that is just slightly larger than the pellet's actual size. Gently lift each planting pellet and place it within a hole in the pot. It's fine to place multiple pellets in a single pot, as long as they are not directly touching. If a pellet doesn't have a visible sprout, you can still transplant it and hope that it will produce a plant in time. Cover each pellet with about 0.39 inches (0.99cm) of potting soil, so that the top of the pellet is no longer visible. Extended direct sun will continue to burn your bamboo seedlings, so make sure that your plants get about half sun, half shade. You might even need to move your pots around to ensure that they get at least 6 hours of light. The seedlings should stay a bright green color. If they turn yellow or brown, then they are getting too much sun.
Position the greenhouse in a spot with 12-16 hours of indirect sunlight. Water the pellets each day until they are moist. Remove the greenhouse lid when the sprouts start to touch it. Transplant the seedlings to larger planting containers after 30 days. Place the pots in a location with at least 6 hours of indirect sunlight.
