Nutrients products are used to help sustain cannabis plants during both stages of development - vegatative and flowering. Proper application of nutrients can play an essential role in the production of quality cannabis, allowing your cannabis plants to grow quicker and larger than they ordinarily would. The products solds are marijuana nutrients are all intended to serve a specific purpose. Each product should be used with care, and according to manufacturer directions.

The main purpose of marijuana nutrient products is to control the NPK content of the water being fed to your cannabis plants. NPK is essentially 'fertilizer' and stands for nitrogen, phosphorous and potassium. NPK can be acquired for many sources, depending on the intended purpose. Cannabis plants however usually need readily available liquid fertilizer for best results. This is because cannabis requires different ratios of NPK at the different stages of growth. Slow release fertilizer can end up producing too much nitrogen in the flowering stage while it's not desired - so be careful.

As there are countless sources of raw nutrients that can be used for cannabis, it has led to hundreds of companies creating their own blend of nutrient products for marijuana. Generally these companies will offer a complete product line of nutrients with a particular set of products for the growth state, and another for marijuana plants in the blooming phase. These blends are carefully balanced with appropriate NPK ratio and will provide your marijuana plants with the changing preferences of nutrients required as it matures.

While you can mix nutrient products from different companies, be careful to follow directions and avoid using two products meant for the same purpose simultaneously. Below you can find a list of top 100 nutrient products. You can click to learn more about the product, review the feeding schedule and see information about the company.
