How to plant weed seeds in a cup

If seedlings get too big for their cups before transplanting to a bigger container, you may accidentally limit your plant’s root space. This slows down growth and can cause puzzling deficiencies! So if you do start in small containers it’s important to transplant your seedlings on time to avoid letting them become rootbound!

In this tutorial, you’ll learn how (and when) to transplant your new cannabis seedlings so they grow as fast as possible!

If you’re trying to keep plants small, small containers can actually be a good thing. But if you want to grow bigger plants, you need to give their roots enough space to “spread out”

Gently water the soil with a spray bottle and situate your pots under a fluorescent lamp. Keep seeds away from the windowsill, as the temperature is too volatile for germination. In general, you’ll want to keep the temperature in the range of 70 to 80 degrees Fahrenheit.

To germinate seeds this way, lay one paper towel on top of a countertop, place a few seeds, and cover them with a second paper towel.

It’s essential to acquire high-quality cannabis seeds for germination, as these will go on to become high-quality cannabis plants. Seeds that are fresh-feeling or too green indicate that they haven’t reached full maturity, while pale-green, white, or very dark cannabis seeds may have trouble sprouting. However, it’s tricky to know the outcome of a popped seed, so trying may be worthwhile. If you’re not ready to pop your seeds yet, store them in a dark, cool place until it’s time for germination.

Cannabis sativa sp. is commonly known as marijuana and has been grown throughout the world for thousands of years. Cannabis seeds germinate in 3 to 7 days, though some varieties may take 10 to 15 days. While germination is a natural process, factors such as light, humidity/moisture, and temperature must be controlled for cannabis seeds to sprout.
