Organic grow nutrition and bud boosters for the best cannabis plants

Indoor and outdoor cannabis growing without chemical fertilizers and pesticides but with organic growshop products is what you can expect at the Growshop by Sirius. Our goal is to provide the supplies and information for the small scale cultivation of organic cannabis for personal consumption. Sirius offers growshop products specifically for ecological and healthy cultivation of cannabis for personal consumption. 

Grow organically and without pesticides. Go for the best organic grow nutrition from Biotabs and BAC. Growing cannabis is officially prohibited in the Netherlands. Therefore grow on a small scale and only for your own consumption!

Can you buy potting soil in the Sirius growshop?

Our physical smartshops 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 potting soil being loaded into cars in front of our smartshop. Also, sending potting soil through the online growshop is an additional difficulty. Good potting soil is not difficult to obtain. Always pay attention to the RHP quality mark. 

In our online growshop assortment you will find the best cannabis grow nutrition and boosters for the growth and flowering of a cannabis plant. Sirius only supplies the top brands in the field of organic grow nutrition in order to guarantee a successful and clean cultivation.

How do you get the best marijuana plants with the biggest yield? 

Everything starts with a good soil life. If this is in order, the plant can develop a good and airy 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. Which results in higher yields and better smell and taste of the cannabis. 

Are you growing indoor cannabis? By installing a ventilation fan you ensure that the air is sucked out of the growing space and the negative pressure causes fresh air to flow 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 cannabis harvest. The growshop exhaust fans that we supply are perfectly matched to the grow tents in our growshop 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 can mimic the wind.

HPS grow lights and LED lamps for cannabis can be found in the Sirius Growshop.

Without light no life, that's easy enough. Since the sun is very important for a cannabis plant, this is the light source in this case. Choosing growshop cannabis grow lights 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 suction and ambient temperature are also important here. To keep the carbon footprint as small as possible and to reduce energy costs, you can choose to purchase an energy-efficient LED lamp. Sirius delivers high quality growshop cannabis grow lights that meet the strictest safety requirements. With reliable and solid materials to connect, hang and control the grow lights. More information about everything in our growshop can be obtained from our skilled staff in our physical smartshops, but also by phone or email.
