If you have gone through the effort to receive your Health Canada legal grow license for medical marijuana or you are eager to start growing four plants under the new recreational marijuana laws in Ontario, keep reading. You might be brushing up or trying to learn from scratch about the best methods for growing cannabis at home. The insane amount of information out there can become overwhelming and even make you feel like abandoning the grow operation altogether, especially when it comes to learning about your plants and proper nutrient intake. But have no fear, here is all the information you need to know about your cannabis plants and nutrients as well as some helpful tips on which nutrient blends on the market are best.
Which elements are most important for growing healthy plants?
There is a number of elements that help your plant to optimally grow; some of these elements are obtained from the soil whereas some come from the air. From the soil, your plants should be able to access nitrogen, phosphorus, potassium, magnesium, sulfur, and calcium. The three most important of these macronutrients are nitrogen, phosphorus, and potassium. When you buy a nutrient solution or fertilizer, you will typically see three numbers listed on the labeling. These numbers indicate the availability of N-P-K (nitrogen, phosphorus, and potassium).
There are also elements that your plants get directly from the air, which are carbon, hydrogen, and oxygen. The best way to ensure that you plants receive enough CO2 – an essential compound for the photosynthetic process – is by installing a carbon dioxide generator in your grow room. There is a number of micronutrients important for plant health, like zinc, iron, and copper. These are required in much smaller doses and trace amounts can typically be found in a number of nutrient blends for sale.
What is the difference between soil nutrients and hydroponic nutrients?
When you grow indoors, there are several different grow mediums you can choose from. Using soil as your medium differs tremendously from using a hydroponic system (which is soil-less). Hydroponic nutrients are often extremely concentrated and should be diluted with water, so be sure to look at the labeling before purchasing any nutrient solutions. The benefit of working with soil is that tons of macro and micronutrients come directly from the soil itself, so you don’t need to go overboard on feeding your plants additional nutrients.
Which nutrient blends on the market today are best for cannabis plants?
There are so many different options when it comes to which nutrients to give your plants. If you are using soil as your medium, consider purchasing the General Organics GO Box. This was specifically designed for soil and the kit includes everything from macronutrients to organic supplements. For hydroponic growing, your best option is General Hydroponics Flora Trio. It arms you with three separate blends of nutrients to use at different phases of the grow operation and tells you exactly how and when to use each blend. This can also be used in soil grow rooms, but is most effective for hydroponics.
