Top 10 weed growing tips

Are you a beginner or experienced grower? Want to reduce errors and maximise your chances of success? Follow up on the ten weed growing tips below. 

1. Buy feminized seeds for the best yields

Feminized seeds are specifically bred without any male chromosome – male plants do not produce flowers or resin. Choosing feminised seeds will save you time, energy and often costly mistakes. If any male plants survive and grow, they will eventually release pollen which will fertilise your female plants. The energies of your female plants will be diverted into creating seeds rather than flower buds coated with resin. The last thing you want!

2. Use fertilisers but sparingly

The soil in which you grow your plants is important, especially if grown outdoors. Providing your plants with compost or fertiliser will help them develop into strong, robust plants with plenty of leaves. However, fertiliser is less important during the flowering stage. It sounds obvious but if using a liquid fertiliser, always follow the instructions on the back of the bottle. If it is not diluted to the correct ratio, you could easily damage your plants, causing them to have root burn or weakened leaves.

We recommend cutting back on your fertiliser program once your plants have developed buds for flowers that are potent and strong, especially if growing for medicinal purposes.

3. Use water for a hydroponic system

The best thing about growing with a hydroponic grow system indoors is that you can take complete control of your plant’s water supply, in addition to the quality and blend of the nutrients contained in the water. These conditions mean that it is relatively straightforward to create the ideal habitat for your weed plants to thrive.

While setting up a hydroponic system might seem a lot more tricky than growing weed outside or using compost, it only takes a bit of time to grasp the basics, and it will result in much less work once the system is up and running.

4. Give your plants lots of light

Cannabis plants need exposure to lots of light to photosynthesise and grow into healthy specimens. If you live in a hot country with lots of sunshine and you are growing your plants outdoors, you don’t need to worry, but if you are planning to grow your plants indoors in a grow tent, it is essential to invest in the highest quality UV HPS, and LED lights you can afford. A desk lamp or two won’t cut it!

5. Pay attention to the temperature and humidity needs of your weed plants

Cannabis plants generally like warm temperatures to thrive, but their needs vary according to their phase in the growth cycle. Seedlings need high levels of warmth and humidity, for example, but plants that are flowering need lower levels of humidity and can cope with slightly reduced temperatures. Daytime temperatures of 18 – 25 degrees C are ideal. Never expose your plants to temperatures that are lower than 12 degrees C as this will have a detrimental and often fatal effect on the health of your plants. Invest in a hygrometer for measuring humidity and a digital thermometer to measure temperature to remove the guesswork from your operations.

6. Plan your grow

Before you get started, work out how much space you will have in your grow room and how many plants you will realistically be able to grow. Decide whether or not to use a grow tent – if you are a novice grower, these are a good idea as it is easier to manage temperature and humidity, they offer protection against pests, and they can be quickly dismantled and stored when not in use. Decide which technique you will use, such as SOG or SCROG or a combination of both. Researching the growing methods before you get started will save a great deal of time in the long run, and the method you choose will determine how many plants you can fit in your grow space.

7. Use strains that are easy to grow

To increase the chances of a successful harvest, always choose seeds that are easy to grow. Plants that are resistant to pests, overwatering, exposure to higher or colder temperatures will make life easy for a novice grower. Look for Indica/Sativa hybrids with a short flowering period. Pure sativa strains are generally more challenging to grow. 

Some strains we can highly recommend:

  1. Ak 47-autoflower 
  2. Gorilla Glue autoflower
  3. Northern Lights

8. Consider which substrate to use if not using hydroponics

Not all soils are suitable for growing weed. The characteristics and composition(pH, EC, etc.) are important elements when growing cannabis, so we recommend using organic soils specifically produced for weed growing.

If you aren’t able to access these types of soil, it is possible to make your own blend at home. There are many ways of doing this, but ultimately, what you want is a spongy, slightly acidic substrate with excellent drainage and moisture retention.

Suggested soil combinations for growing weed:

  • 25 percent yellow peat
  • 30 percent black peat
  • 15 percent coco coir
  • 20 percent perlite
  • 10 percent Worm humus

Mix all these by hand using a large wheelbarrow – just as they do in gardening programmes.

9. When should I switch to flowering?

There is not a set date for switching to the blooming phase, but it depends on several variables related to the plants’ growth stage, such as genetics, height, nutrients, and growing systems.
A good rule of thumb is to wait until over half of the growing space is blanketed by the canopy. This will allow the plants to cover all the space in a few weeks, before starting to develop buds.

10. Know when to harvest your cannabis

Harvest is undoubtedly one of the most exciting times for the grower. To find out whether your plants are ready, look at the trichomes with a magnifying glass and see if they are ripe.
