starting cannabis seeds in solo cups

The first time you grow a new strain, your not going to know how fast those roots are developing, so if you can, error on the safe side and go with a larger container. However, with autos the limit seems to be around 7 to 10 gallons. The plants only get 1-2 feet, so anything beyond 10 gallons is over kill IMO. In fact, many do fine in 3 to 5 gallons containers. A lot also has to do with your particular setup (timers, feeding frequency, planting medium, etc).

Start in the solo cups. I recommend using fox farms light warrior mix to start seedlings and new cuttings. after 2-3 weeks you can transplant into fox farm ocean forest or whatever soil you want.

You always want to have two inches of space between the root tips and the edge of your container. As long as you do that, you can pot up as often as you want. Larger containers means less watering and feedings, but it also means less room to grow plants. So you have to find a balance.

What has always worked for me is starting in 1 gallon smart pots using a good potting mix formulated for seed germination (I use Miracle Gro Seed Starting Mix), then I make sure to transplant before the end of the third week. Any longer and the roots will start poking out the bottom and sides of the smart pots. It also helps to let the plants get a little dry but not wilting just before transplanting and water immediately afterwords.

edit. just realized they are autos. you can still start in solo cups
. you just don’t want them to stress during transplant. so be careful that’s all

Matured marijuana seeds shell tends to be very hard, darker brown or deep tan, with lighter accents (stripes). If they look fresh and green, it means they didn’t reach full maturity, they’re pretty much useless .

There are many reliable outlets sell high quality seeds, here is a list of The Best Online Seed Bank for Feminized Seeds that ship to the USA, in the industry. These seed banks have strong reputations and are known for providing high quality genetics.

Mature Cannabis Seeds, This Is What You Need to Do

Important tips to ensure successful germination for the marijuana seeds:

Due to the limited root system the germinated seeds have, best practice is to plant the germinated seeds in small containers. This will increase the plants’ accessibility to oxygen and nutrients by avoiding overwatering.

Check your germinating marijuana seeds at least once a day. You will probably need to add more distilled water as they begin to dry out. You don’t need to completely drenched the paper towel, but it should always be damp to the touch. Once the seeds split, you will see a single taproot coming out (see the picture below). You will know that your beloved cannabis seeds are successfully germinated.

4-6 gallon container

Should I start in a solo cup or in a bigger pot?

10+ gallon container

If you start seedlings in a solo cup, you should try to transplant to a bigger pot around the time the leaves reach the edges of the cup. This seedling is ready for transfer!

6-8 gallon container

I think it’s a matter of preference. Just as a quick summary: It’s easy to give too much or too little water to a very small seedling in a big pot. With a solo cup, you just soak the grow medium and the roots get a lot of both oxygen and water at all times because the medium dries out quickly. The downside is you have to transplant a seedling as soon as the leaves reach the edges of the cup, or its growth starts slowing down. Also, if you’re not careful you could possibly shock the plant during transplant.
