How To Grow Cannabis From Seed (The Right Way)
HOW TO GROW CANNABIS FROM SEED (THE RIGHT WAY)
Everyone has an idea of how to grow cannabis from start to finish. Here it is, laid out in plain English. No more wasting your precious seeds. You no longer have to guess. No more cursing into the sky. Here is a step-by-step, proven method for cultivating cannabis from start to finish.
- Place your seeds in a glass of tap water or bottled water
- Put the cup in a cool place for 1-3 days. The seed will crack, and a tap root will appear.
3. Once you can see the taproot, place the seed in your medium of choice. Rockwool is the preferred method. You can buy our rockwool cubes in our Online Store. Make sure the Rockwool is damp (not soaking) when you add your seeds.
4. Place your Rockwool with the seeds inside them on a window or in a Mini Greenhouse sill in a room with a temperature of 72-76°
5. The first set of true leaves will appear.
6. For the next 20 days, give the young plant pH tested tap water only, without nutrients. Provide 18 hours of light, 6 hours without light.
7. After 20 days, transplant to a larger container. *Remember, the larger the root mass, the bigger the bud*
8. Next (and this may hurt a little. You, not the plant), top the plant by removing the top 4-6 inches of the plant to help determine the sex of the plant early. Take the part you cut and place it in a glass of water. Give that cutting 12 hours of light, followed by 12 hours of darkness for 2 weeks. After those 2 weeks, you will be able to identify the sex of the plant. Now you can get rid of the males and hermaphrodites.
9. After 3 weeks, add 25% nutrients.
10. Once the plant has reached 18″ (or your preferred flowering height), change your light schedule to 12 hours of light, 12 hours of total darkness, to initiate flowering.
11. Cleanup the lower leaves of the plant, and make clones for yourself.
12. For the next 2 weeks the plant will really grow. This is the right time to train and control your plant’s height to create a nice canopy. See our blog post on Training Tips.
13. Keep an eye out for any large fan leaves that are block light from getting to the bud sites. Remove those leaves.
14. After 3 weeks of flowering, increase your ‘bloom’ nutrients to 3/4 strength. Remember that over feeding your plants causes more harm than under feeding them.
15. Keep the temperature of the room between 68-73° and the relative humidity at 45%.
16. Make sure that no light can reach your plant during the 12 hours of scheduled darkness.
17. After 5-6 weeks of flowering, increase the flower nutrients of potassium and phosphorous, and decrease nitrogen. You can find a wide range of Flowering Nutrients in our store.
18. For weeks 6-8, add a bloom booster of your choosing.
19. Week 8: Nutrient flush. Using tap water helps flush nutrients and salt buildup on the roots.
20. Begin your harvest by removing large fan leaves. Cut the plant down to fit your drying capabilities and hang upside down to dry in a cold, dark area with 40% relative humidity and lots of air circulation. If you can temper the humidity, use a basement. If in a garage, cover the windows and get the area as cold as possible. Cold conditions are ideal for drying purposes. The colder it is the tighter the nug, the warmer it is, the looser the nug.
21. After 10 days, begin the snap test by breaking the branch. If the branch snaps begin to remove buds and place on a net or screen for 3-5 days to finalize drying. If the branch bends there’s still too much moisture and the buds need more drying time.
22. Now we’re at the cure stage, which will make or break all your hard work either as a treasure or moldy trash. Use Rubbermaid tubs or gallon size Mason jars with a rubber gasket. You’ll want something with an airtight seal.
23. Put your bud in a container so that it is lose enough to move around, but not over packed. Burp for 1-2 hours a day, (depending on bud moisture and amount in container) 2x/day for the first 10 days. Then, burp once a day every 10 days after. Make sure to move the amounts in your container around to circulate the air inside as evenly as possible. A lack of burping and movement will cause mold and destroy what you’d worked to build in the first place.
