can you germinate weed seeds in a cup of water

The paper towel can dry out, so put a bowl or another plate on top to trap the moisture. Alternatively, you can spray the towel every five hours to keep it wet. The process can last one to four days, so check periodically to see if the taproot appeared. If you have older seeds in the paper towel, you may end up waiting longer. Afterward, you can place the young seedling into a growing medium.

Another way of germinating cannabis seeds is by using wet paper towels. The best type of paper towel to use is the cheap kind. It may seem strange, but the cheaper ones tend to be non-porous. Non-porous is preferable since the newly sprouted roots will not grow into or get stuck to the paper towel. So, you can save a bit of money.

Other than drying out over time, one disadvantage of the paper towel method is that there is a chance of hurting the taproot. Be careful when checking on the seeds, and do not move them too much.

Water (recommended)

While cannabis seeds primarily need to remain moist, you can soak them in water overnight. All you need is a glass cup. Fill it with three-quarters of a cup of water that is filtered or pH neutral. Make sure the temperature is neither cold nor warm. The ideal temperature is lukewarm.

You only have to worry about making sure the seeds are not soaking for too long. The method is more effective when you follow it up with the paper towel method. Damp paper towels can help get any remaining weed seeds to sprout.

A disadvantage of soaking the seeds in a cup is that too much water can be damaging. The excess amount can rot the newly emerged root. Those that have not sprouted yet will drown if left soaking for too long.

Now that you know how to germinate cannabis seeds, the next step is to plant the sprouted seedlings. You do not need much in terms of planting. For example, you will want a large enough pot and a plant sprayer. If you used incandescent bulbs to keep the seeds warm, switch them out for actual growing lights.
