The seeds should start sprouting in about two days, though older seeds can take up to a week to sprout. You can remove them from the water and place them in the soil at any point once they’ve sprouted. Once the roots are about five millimeters long, they need to be planted.
The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.
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.
The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds.
Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild.
If you’re going to indulge in single-serving packaged foods such as yogurt cups, at the very least you can give them a second life by making the plastic containers into small seedling pots. The larger yogurt containers will work as well, but take up much more room, so in this case, the smaller yogurt cups offer more versatility. Cut a series of small holes around the bottom edge for drainage, and after planting the seedling into the garden, wash and dry the cups for use again and again.
Planting season is rapidly approaching, and if you have a sunny window, you can get some of your veggies started indoors right now. The sooner you start your seeds, the bigger the plants will be when it’s time to put them in the soil, and the quicker you’ll be able to begin harvesting food from your garden.
If you regularly get coffee or tea in a paper to-go cup (because you keep forgetting your reusable mug, of course), or can raid the office trash or recycle bin for these, they make great seedling pots as well. Be sure to punch some small drainage holes in the bottom, and when you’re ready to plant them in the garden, you can pull off the bottom of the cup and plant the rest, or remove it entirely and add the old cup to your compost pile.

Not everyone uses paper towels, but pretty much everybody buys toilet paper, and the paperboard tubes in the center of both of these items can be cut to form small seedling pots. There are two different methods of making pots from these paper tubes, one of which is to just leave the bottom open and fit the tubes tightly together in a tray (easiest), and the other is to cut several vertical slits in the bottoms of the tubes and to fold the resulting flaps to form the bottom of the pots (takes more time, but the soil won’t come spilling out the bottom if you pick these up).
If you’ve got egg cartons, you probably have egg shells as well, and while they can be crushed to make a great soil or compost pile additive, egg shell halves can be used as seedling pots as well, and naturally, they fit perfectly inside an egg carton tray. A small hole will need to be punched in the bottom of each shell for drainage.
Cardboard egg cartons can be used to start a dozen seedlings, and then cut apart to plant each one when it’s time to plant them in the garden. As with newspaper seedling pots, there’s no need to remove the plants from the pots before planting, as the cardboard will break down in the soil as the plant grows.
Most garden centers sell plastic trays and pots, soil blocks, or peat pots to use for starting seeds indoors, but if you’d like to start your seeds without having to go purchase a bunch of new stuff, there are a bunch of inventive DIY seed pots that can be made from items you probably have in your recycle bin right now.
When you want to move the box, move the plastic, wood, or metal with it to prevent the bottom from dropping out.
On the other hand, if you want to make your cardboard boxes last longer, you should use plastic bags or sheets to line the inside and outside of the box. This will prevent rain, watering, and sunlight from speeding up the decomposition of the box.
Use Cardboard Boxes To Kill & Prevent Weeds
This method is great because you can transplant the seedlings directly into the soil in your garden – cardboard box included. Over time, the cardboard box will decompose and provide nutrients and organic material for the soil (and for your plant!)
You can also make plant collars out of other materials – for more ideas, check out my article on making plant collars.
This will keep your plants healthy, since infected soil on plant leaves is a major cause of disease spreading through a garden. For example, fungal spores that cause blight can spread when wet soil splashes around.
