Growshop online

Not only in the shops of Sirius in Maastricht and Roermond, but also online you can find all the necessities for the small-scale cultivation of cannabis for personal consumption. We only sell products of the highest quality to ensure safety. Germination, growing, flowering, harvesting, drying and curing, we have everything you need for a complete grow. Are you a beginner grower or do you already have some experience with small-scale growing, with us you will find the stuff for a successful grow. Besides the necessary materials you can also check out our encyclopedia or visit our physical stores for more information about the products and cultivation process. We do not want to encourage anyone to grow cannabis, but we have noticed that more and more people want to grow their own cannabis for their own well-being. Our goal is to provide the supplies and information necessary for the small-scale cultivation of cannabis for personal consumption. So it can take place in a clean, safe and responsible manner, both recreationally and medicinally.

Soil

In order to grow good cannabis it is important to provide the plant with the best conditions during growth and flowering. It starts with a good soil life. If this is in order, the plant can develop a good root system. This is important! Because without a good root system no healthy plants. So the better you take care of the root system, the better the plant will do. Resulting in higher yields and better smell and taste of the cannabis. Our stores are located in the inner cities of Maastricht and Roermond. Because of the negative stigma on cannabis, we do not like the image of bags of soil being loaded into cars on the sidewalk. Shipping via the webshop is an additional difficulty. Good potting soil is not difficult to obtain. Always pay attention to the RHP quality mark. In our assortment you will find the right foods and additives for the growth and flowering of a cannabis plant. Sirius supplies only the top brands in the field of organic food to guarantee a successful and clean grow.

Air

Everyone needs fresh air. So does a cannabis plant. It is therefore very important to pay the proper attention to this. By placing an extraction fan you ensure that the air is sucked out of the growing space and through the underpressure fresh air flows into the vents. In this way an air circulation is created. If the suction is too large, there is a chance that too much heat will be drawn out of the space. And with too little suction, the humidity can become too high. In both cases this has a bad influence on the harvest. The extraction fans that we supply are perfectly matched to the grow tents in our range. But we also supply separate parts. In the last weeks of blooming a cannabis plant produces an enormous smell. Therefore, always use an active carbon filter and prevent odor nuisance! By placing a small fan in your growing space you mimic the wind.

Light

Without light no life, easy enough. Since the sun is very important for a cannabis plant, this is the light source in this case. Choosing lighting depends on where you want to grow and how you want to grow. An HPS lamp produces more heat than an Led lamp. This can be a disadvantage but also an advantage. The extraction system and ambient temperature are also important. To keep the carbon footprint as small as possible and to reduce energy costs you can choose to buy an energy efficient Led lamp. Sirius delivers high-quality lighting that meets the most stringent safety requirements. With reliable and sound materials to connect, hang and control the lamps. Let us inform you.

Grow consciously!

Measuring is knowing. Sirius has a large assortment of digital measuring devices to measure temperature and humidity in the grow room or to determine the acidity of the cultivation medium. This way you can monitor the environment and adjust where necessary. Grow organically and without pesticides. Growing cannabis is officially prohibited. Therefore grow on a small scale and only for your own consumption! Do this in a safe manner and do not bother anyone.
