Feeding cannabis plants can be a challenging task for novice medicinal growers. As a result, providing too much or too little is among the most common growing mistakes. Fortunately, there are also simple ways to feed cannabis plants, useful for beginners.


Choose soil

Practically the easiest way to feed cannabis plants is to grow them on the soil. Earth has a buffering effect and will often catch feeding errors. If you want to get through a cycle quickly and without many feeding problems, it is best (after the first few weeks) to report to a large pot. 

In a pot of about 15 liters with well-fertilized soil, you may even be able to grow a whole crop without having to add nutrients. The larger the pot, the more nutrition the plant already has at its disposal.

The nutrients in the soil will be depleted quickly in a small pot, which means that you will soon have to add nutrients and run the risk of making nutrition mistakes. So it’s better to choose a slightly larger pot to repot your seedling in after the first few weeks. 

Large pots also mean that you will have to water less often because more soil retains more water. This helps, especially during the hot summer, against dehydration. Small pots may need to be watered almost daily.

Slow Release Plant Food

Buy well-fertilized soil in a grow store. Soil that you buy in garden centers is less suitable for growing cannabis plants. The quality of such soil leaves much to be desired, and the nutrients are not sufficient for the entire cultivation of a cannabis plant. 

A well-fertilized soil from the grow shop usually contains enough nutrients for about six weeks. You can also choose a so-called light mix soil. In that case, the soil has nutrition for about two weeks.

After these six/two weeks, you will probably need to supplement with a unique nutrient for cannabis plants. The easiest way to do this is by using so-called slow-release plant food.

You mix these products through the soil according to the instructions, after which you only need to water. The nutrition is released slowly so that your cannabis plants always get enough food.

If you are using liquid fertilizer, do not give them the amount stated on the bottle immediately but about half of it. You can always provide more nutrients, but flushing nutrients out of the soil is much more difficult. 

Feed about twice a week. This will ensure that your plant has enough nutrition for the entire cultivation period.

Nutritional mistakes

Sooner or later, you will have to deal with a shortage or over-fertilization. That’s why it is essential to take a good look at your plants so that you can catch any issues early. 

Also, remember what you do spot issues: write it down so you know where it went wrong when it goes wrong. If you learn from your mistakes, you won’t have to make them again. 

Five tips for growing Sativa cannabis plants indoors


Beginning home growers don’t usually choose sativas because of their height and more extended flowering period. But what if it’s the medicinal properties of sativas that you’re after? With these 5 tips you can grow medicinal sativas even as a beginner! 

When you stick to a few basic principles, growing a sativa is no more difficult than growing an indica. Of course, sativa-dominant cannabis varieties flower longer and often get bigger, but you can take that into account as a grower. 

In addition, growing sativas also has advantages for growers, and not just in terms of smell, taste and effect.

Sativa’s often have enough with a short growth phase. They grow longer after you put them on a 12/12 regime. In the summer, Sativa’s are better able to withstand the higher temperatures in your growing space. 

Sativa’s also tends to be less prone to bud rot when there is high humidity. Sativa is also a quick to dry weed. Here are five growing tips to keep in mind when growing sativa dominant strains indoors.

1. 12/12 a little earlier

Don’t mistake a sativa’s growth spurt after you set the clock to 12/12. The stretching phase that precedes flowering in all cannabis plants is faster and lasts longer in a sativa. So please don’t wait too long to switch to 12/12, and count on the fact that a sativa dominant strain of weed will grow more than twice its size in many cases.

2. Choose a fast sativa

Sativa dominant hybrids flower shorter but offer the same effects. 

Some sativas flower as long as 20 weeks or more. These types of almost pure sativa weed varieties are therefore not very suitable for the average home grower. It is, therefore, better to choose a sativa dominant hybrid that also has some indica influence.

Good sativa-dominant hybrids are much easier to grow, bloom up to 11 weeks and often have that typical spicy-sweet taste and give a high uplifting effect.

3. Give sativas lots of light

Sativa’s originate from warm areas with long summers. So treat your sativa indoors to something more tropical and give it lots of light. An advantage in the summer is that a sativa, thanks to its origin, can also cope better with the heat.

4. Easy on the nutrition

Sativas may stretch a lot, but they still like a light diet. Again, this has to do with their origins; sativas often grow on infertile soil in nature. In addition, sativas take longer to bloom, and bud development is also slower. So give enough water but go easy on the nutrition.

5. Quicker flowering

Especially in the last period of the flowering phase, a sativa produces most of its flavor compounds. To speed up that ripening phase, you can shorten the day length in the last two weeks to 8 hours instead of 12. The longer nights produce more bloom hormone, which makes for faster ripening.
