Cannabis Growing – Grow Guides & Tips

Interactive Cannabis Grow Calendar

A cannabis grow calendar helps you plan the timeline of a grow: When should cannabis seeds be germinated, when should you repot, top or fertilize – and when does harvest time finally begin? Instead of merely describing the plant’s developmental stages, this calendar shows which tasks and checks become relevant during each stage of cultivation...

Mother Plant: Selection, Care & Keeping

A cannabis mother plant is a selected female plant that is kept permanently in the vegetative growth phase in order to preserve and propagate its genetics through cuttings. Unlike a plant cultivated for flower production, a mother plant should not enter the flowering phase. Instead, it should remain healthy in vegetative growth over a longer period and produce strong side shoots from which cuttings can be taken regularly. These can be rooted and cultivated further as genetic copies of the mother plant...

How to Clone Cannabis: Cuttings & Rooting

A cannabis cutting is a detached part of a plant that develops its own roots and can then continue growing independently. Unlike propagation from seed, the genes of two parent plants are not recombined. The plant material comes directly from a mother plant and has the same genotype as the mother plant. This is why cannabis growers often refer to cloning...

Electricity Cost Calculator for Indoor Setups

When growing cannabis indoors, several electrical devices may run for many hours each day. In addition to the grow light, these include exhaust and circulation fans, controllers and, depending on the location, dehumidifiers, heaters or air-conditioning units. Anyone who wants to realistically estimate ongoing costs should therefore consider more than just the power consumption of the light...

VPD for Cannabis: Calculator & Values

Anyone who looks only at relative humidity when growing cannabis indoors overlooks an important relationship: how much water the air can hold depends largely on its temperature. VPD for cannabis therefore combines temperature and humidity into a more meaningful value for assessing the plant climate...

Guerilla Growing: Guide, Location & Strains

The term Guerilla Growing refers to cultivating cannabis in remote, discreet outdoor locations outside conventional growing areas. It is characterized by the use of natural environmental conditions, with sunlight, rainfall and soil providing much of the plants’ needs and care usually taking place only at longer intervals. The successful development of the plants depends on numerous factors...

Cannabis Climate Map: find the right strains for your Climate

Cannabis can generally grow in very different regions. Nevertheless, genetics vary considerably in how they cope with short summers, high humidity, heat, drought, or early autumn rain. A strain that matures without difficulty in southern Spain may enter the flowering phase too late in northern Germany. Conversely, a compact, fast-maturing line may suffer more from heat stress in a very hot area than a more open-growing, tropically influenced genetic line...

Sea of Green for cannabis: planning and implementing it correctly

With Sea of Green, you use many small plants that together form a dense, as even a surface as possible. This fills the available grow area optimally. The lamp does not shine onto empty soil, but onto a closed canopy. Every corner that is not used by plants costs efficiency. A Sea of Green solves this problem, the plants remain compact, enter the flowering phase early and...

SCROG Growing: How to Use the Screen of Green Method for Cannabis

If you have been growing cannabis indoors for a while, you have probably hit a point where you want more from each grow. More yield, better light coverage, fewer wasted bud sites sitting in the dark. That is exactly where the SCROG technique comes in. It is not complicated, but it does reward growers who pay attention and stay consistent during the vegetative phase...

When to Harvest Cannabis - The Right Time

You can choose perfect genetics, dial in your nutrients, maintain ideal temperature and humidity for twelve weeks straight - and still ruin most of that hard work at the very end by harvesting at the wrong moment. Harvest timing is not a minor detail. It is the final, decisive variable that determines potency, flavour, aroma, and the overall effect of everything you have grown...

The best medium for cannabis: soil, coco or rockwool

Cannabis seeds contain the genetics, but the growing medium shapes the early root environment. Even strong genetics need a medium that provides oxygen to the roots, retains enough moisture, and ensures stable access to nutrients. That is why choosing the right medium should never be treated as a minor detail.

The same seed can develop very differently in heavy soil, light soil, coco fiber, or rockwool. Some media are more forgiving of mistakes, while others offer greater control...

Grow Cannabis on your balcony with Autoflower Strains

There are a lot of reasons why you might want to use your balcony or terrace to grow a weed plant. For one thing, the sun does not send you a bill at the end of every month.

If it rains, you are getting high quality water for free as well. You do not really need to buy ventilation systems either because the wind outside will keep the air moving and replenish the carbon dioxide levels...

Watering cannabis and hemp correctly - a guide

In this guide, you get exactly that: a simple routine that beginners can implement immediately, plus the details that advanced growers expect (water quality, pH/EC, substrate differences, irrigation methods). And if it has already happened: cannabis overwatered what to do – with a rescue plan based on severity...

Topping Cannabis Plants

Topping is one of the most reliable methods if you want to make the plant a little stronger and at the same time better control its height. Many growers in Europe have been doing this for decades, not because it is a trend, but because it simply works.

When done correctly, the plant forms more main shoots, the crown spreads more naturally and the light is used more efficiently. This guide explains how topping actually works, when is the right time to do it and what to expect during the recovery phase...

Germinating seeds correctly is not difficult

When you google “Cannabis Seed Germination”, you don't want a theory lesson on botany. You want to know: How do I get this seed to pop without ruining it? Germination is the most critical moment in the entire grow. One mistake here (too wet, too cold, and touched too much) and the seed is lost. That is why we have designed this guide entirely for practice. Instead of just listing methods, we guide you step by step...

Storing Cannabis Seeds correctly - best methods to store seeds

Cannabis seeds are living biological material in a dormant state. They are built to survive a “pause” between seasons, but they are not indestructible. Over time, stored seeds slowly lose vigor. When storage conditions are poor, that loss speeds up and can show up as slower germination, uneven sprouting, or seeds that never crack at all...

Cannabis Flowering Stage - Week by Week - guide

The cannabis flowering stage is that turning point where a plant finally stops focusing on growing stems and leaves, and starts putting all its energy into developing flowers. It's the moment the plant starts looking, smelling, and behaving totally differently. Bud sites pop up, white pistils stretch out, the smell gets super loud, and you'll start noticing sticky resin coating the sugar leaves as harvest gets closer...

Growing cannabis outdoors – a guide by Cannapot

Cannapot has worked with European cannabis genetics for many years and gathered a lot of practical experience along the way. This guide focuses on what really matters in outdoor growing: no complicated theory, just the basics that actually work in real-life conditions.

It covers laws, choosing the right seeds, climate, location, watering, harvest timing and common mistakes growers can avoid from the beginning. Everything is explained clearly and based on real cannabis growing experience.

Top 10 best cannabis seeds for indoor

Indoor growing can look technical at first. In reality, it often feels calmer, more controllable, and easier to manage than an outdoor project.

You control the light, airflow, timing, and space. That is exactly why a good indoor grow does not start with equipment alone. It starts with genetics. The right seeds can make the difference between a stressful run and one that feels smooth from start to finish...

Germinate Cannabis Seeds Outdoors in Europe

Across much of Northern and Central Europe, the safest outdoor route in 2026 is to germinate cannabis seeds indoors in March or April, then move seedlings outside from mid-May onward once nights are mild and the soil has warmed up.

In Southern Europe, earlier starts are often possible. In colder inland and mountain areas, waiting longer is usually the better choice...
