These marijuana growing supplies cannot be missed

Growing Information

Would you like to grow some cannabis plants in your own home? If so, read on as this guide to all the marijuana growing supplies you need will help you to grow marijuana indoors easily.

How much does it cost to set up a grow space?

The price of cultivating cannabis indoors for the first time varies considerably. At one end of the scale, the grow space could feature nothing more than containers, lights, soil, and a padlock. At the same time, a high-end set-up could come fully equipped with several grow spaces, high tech automatic fertilisers and lighting schedules, environmental analytics, and more. You could pay anything from £2500 for a luxury installation or as little as £75 for a basic grow tent. It’s wise to spend as much as you can afford, but a simple grow tent is ideal for a novice grower, although you will need to purchase additional pieces of kit, such as lights and carbon filters.

Growing indoors or outdoors?

Growing cannabis indoors is less risky than outdoors because you can hide your grow equipment in your home away from prying eyes. And you also don’t have to worry about the weather – weed needs a lot of sunshine.

Your grow box or grow tent should be placed in a small space such as a wardrobe, garage, cellar, attic or even a garden shed.

If you are growing somewhere where growing weed is frowned upon by the authorities, it is essential to make sure that the space is secure and cannot be accessed by anyone else. Try not to tell anyone about it – however excited you are!

You will need a power supply, and a window or another source ventilation to eliminate the used air. There should be a way for fresh air to access the room.

The cannabis growing supplies you need

When growing marijuana indoors there are some supplies you definitely need. These are the weed growing supplies we recommend to get started.

  • Grow box
  • Ventilation
  • Pots and earth
  • Fertiliser
  • Hygrometer for measuring humidity
  • Thermometer
  • Grow lamp sets
  • Lights


Lightning is besides water one of the most important growing supplies you need. We recommend buying LED grow lights. These are just as good in quality and function as HIPS lights but slightly more expensive to buy. The advantage of growing weed with LED lights is the limited electricity you need.

CFL lamps are also an option if you only want to grow two or three plants; a single 150 watt CFL is sufficient for several small plants to be raised.


Everything needs air to breathe, and weed plants are no exception. Cultivation areas that are not adequately ventilated are prone to develop pests such as spider mites that can harm your crops.

Old used air must be evacuated through a window or a vent. The activated carbon filter of a ventilation system eliminates the unmistakable aroma of weed so that other people cannot smell it. Very small set-ups with only 1 CFL lamp can be operated without active ventilation.

Grow tents

Grow tents have many advantages. They keep the bright lights inside, and the smell of plants can be removed directly by the ventilation. Most grow tents also have a reflective interior to direct all the light onto the plants. They also feature an opening for fresh air to enter at the bottom and exhaust the used air at the top, as well as convenient apertures for the electrical connections.

There are many different sizes for every conceivable space, and they also have waterproof floors and are easy to clean to minimise the damage of the inevitable spills.

Seeds or clones?

Another important part of your cannabis growing supplies is either buying seeds from a reputable seed bank or using clones (cuttings), both of which have their advantages and disadvantages. If you opt for seeds, for example, you will have to wait for several more weeks until harvest because of the germination process. Still, you will be able to choose from hundreds of different varieties and choose a strain with your desired characteristics.

Feminized cannabis seeds are recommended as all seeds produce female plants, so there is less wastage. If you have regular, non-feminised cannabis seeds, you will end up with around 50% males and 50% females.

Clones are easy to grow and smaller so ideal for indoor grows. They also reach harvest in less time, but yields are likely to be less. If buying clones from an illegal market, you will have less choice, and you will also need to quarantine your plants before putting them in your grow room.

Choosing the growing medium

But there are more growing mediums like soil, and they all have their advantages and disadvantages. In any case, they are there for a reason, let’s see what the options are when choosing a suitable medium, the substance which holds a plant’s roots. In nature, this is just soil for cannabis plants. However, for indoor cultivation of cannabis (and many other crops), you can also choose an alternative to soil.


Soil is pure nature, usually already contains some nutrients, and due to the buffering effect, an error, such as a little or too much nutrition, does not always immediately lead to problems. However, of course, there are also disadvantages.

If you are going to grow weed, the plants must be in good soil in which nutrients are present in the right proportions. You can use potting soil from the garden centre, but this is usually of poor quality. A speciality store does have the right soil and earth mixtures. The quality of an earth mixture is determined by the combination of a good structure and the correct nutritional and pH value. Cannabis plants like an airy structure, which ensures good drainage and oxygen at the roots.

Basically, a soil mixture consists of potting soil, fertilisers (from bat droppings to beef poop) and a structure improver such as perlite. Grow shops sell soil with the ideal proportions for our plants, but you can also mix yourself.

  • Organic natural product
  • Buffering effect
  • Can be pre-fertilised
  • Better tasting weed (according to some)
  • Economical
  • More susceptible to vermin
  • More difficult to flush
  • Heavy

Rock wool

Rock wool was discovered by accident when American scientists found strange white strings in trees near a volcano in Hawaii. According to the locals, it was the hair of a god who lived in the volcano. An investigation showed that it was cooled volcanic rock that had been blown apart by the wind. Around 1850, this volcanic rock wool was copied in a factory, after which it was used as heat, sound and fire insulation. In the early 1970s, horticulture started to experiment with rock wool. From that moment, it became one of the most used mediums in the breeding sector.

Rock wool comes in many shapes and sizes. All crops have a different root structure, which is why there are different types of rock wool on the market. The soft varieties absorb a lot of water, but the roots of a cannabis plant do not like that. If the material is too hard, the plant has to work harder to create roots, which is a waste of energy. In short, it should not be too soft, but not too hard either. Grow shops naturally sell the ideal rock wool for our plants. The range includes germ plugs, mats and rock wool flakes.

  • Great water retention capacity
  • Contains a lot of air
  • Lightweight and Reusable
  • Optimal control of nutrients
  • Less susceptible to pests
  • Too high pH value (must be acidified)
  • No buffering effect
  • More growing experience required
  • More expensive to purchase
  • Translucent
  • More sensitive to algae growth

Coconut fibre

Coconut fibre or coconut coir has been used for centuries as a raw material for rope and as a lining for mattresses and chairs. The fibres from the outer shell of coconut were first used as a growing medium in the mid-19th century. However, because there was insufficient knowledge at the time, many problems arose that prevented coconut from breaking through as a growing medium. That breakthrough came eventually, a century later.

  • Organic natural product
  • Better taste (according to some)
  • Semi buffering effect
  • Can be pre-fertilised
  • Light, airy medium
  • Good control of nutrients
  • Dries out quickly
  • More sensitive to the fungus fly

Clay granules

You often see these granules in large planters in commercial buildings or hotels. These are baked clay granules that have become porous due to the high cooking temperature. Due to their structure and shape, they retain oxygen and water well and are pH neutral. The granules come in all sizes and can be used in different ways. For example, you can use the tiny pellets to make an earth mixture airier for better drainage and so that more oxygen gets to the roots.

However, a full hydroculture is also possible. The plants are then placed in a pot filled with granules, and the roots hang in a container with water. It is also possible to completely convert the roots into granules. Water is then pumped to the granules with feed employing a pump.

  • Versatile
  • Reusable
  • Optimal control of nutrients
  • Great water retention capacity
  • Airy
  • No buffering effect
  • Less support for the roots

Fertiliser and water for your weed plants

Beginners often over water and overfeed their plants, and generally pay them too much attention. Before you know it, the leaves are burning from the food, and the roots are rotting due to the soaking wet medium.

If you want to spoil your cannabis plants, provide plenty of the right kind of light, an optimal climate and lots of patience. Plants grow at their own pace; you cannot accelerate that with water and plant nutrition.

Plants grow most quickly with light and customised plant food and water. The type of fertiliser and the amount depends on lots of factors, the stage in the growth cycle, the growing medium and the strain of weed, so it is worth doing some research before investing in feed

Watering to measure

You can use tap water but leave it to stand for a few hours to give any fluoride or chlorine a chance to dissipate. Of course, you will need a watering can. Choose a medium-sized can with a removable rose to avoid the water gushing out and potentially damaging the roots. Seedlings and young plants must be watered very carefully.

Reading tip: How often do you water weed plants?

There are many tips and tricks to ensure that you do not water too much or too little. For example, you can lift cannabis plants in pots daily to get a good feeling of the weight when your plant has little, enough or a lot of water. Another trick is to let the top four, five inches of soil dry out between each watering. But by far the best thing is to simply look at your plant’s leaves, which indicates in detail whether it is too dry, has enough water or has too much water.

The leaves of cannabis plants are the best indicators to see how the water balance is doing. The leaves will droop and hang if they are thirsty. Of course, you should not let it get that far, but try to tilt the leaves upwards towards the light. That is how your cannabis plant indicates that it is at least doing well in terms of water.

When a cannabis plant is too wet, you can easily see that in the leaves. In that case, the leaf fingers curl down in a kind of claw-like shape. Don’t confuse it with limp leaves; in the case of too much water, the leaves feel firm. The leaves indication method works for cannabis plants on earth as well as cannabis plants that are grown in hydro systems.

Give fertilisers to measure

Even when it comes to nutrition – or rather fertilisers – the leaves of your cannabis plant are excellent indicators. Of course, there are feeding schedules that indicate exactly how much of a given plant food a cannabis plant should have from week to week, but every situation is different. It is, therefore, always better to observe your cannabis plants.

Whether you grow on soil or use a hydro system, the leaves pinpoint whether they need fertilisers or not. They should have a beautiful fresh green colour during the growth phase and most of the flowering period. When you start rinsing at the end of the flowering stage, the leaves turn yellow due to a lack of nutrition and simply because the cycle is over. This is normal and not a reason to feed more.
