Choosing the Best Nutrients for Weed: The Ultimate Buying Guide

Like any other plants, marijuana needs the right nutrients to grow. It doesn’t matter if you are growing it in soil or a hydroponic system. With the right nutrients in precise amounts, your weed plants will yield the high-quality buds and flowers for your vaping or smoking delight. Here are questions to ask yourself before settling on a particular nutrient formulation for your weed plants:

What Nutrients Does Weed Require To Grow And Thrive?

For proper growth, weed requires nitrogen (N), phosphorus (P), and potassium (K). Depending on the stage of growth, these elements need to be applied in the right ratios. At the vegetative stage, use a lot of nitrogen and the other two in moderation. That’s because nitrogen encourages the faster growth of roots. Additionally, nitrogen promotes the faster growth of the entire plant. It makes it greener and beautiful. Small amounts of phosphorus give the plants the ability to resist disease and quickly absorb nutrients. On the other hand, potassium strengthens the plant.

At the flowering stage, the plants need high amounts of potassium and smaller amounts of nitrogen and phosphorus. Potassium promotes the development of high amounts of terpenes in addition to promoting the proper formation of the buds. It also maintains optimal health and helps the leaves look lively.

So the nutrient composition you buy for your weed depends on the stage of growth. Choose only what your plants need at whichever stage they are. If at the initial vegetative stage, buy a supplement with lots of nitrogen. When the plants are just about to flower, a high amount of potassium is what your plants need.

Do You Prefer Chemical Or Organic Nutrients?

There are two types of nutrients for weed. They can either be chemical or organic nutrients. Chemical nutrients are the best when it comes to faster growth. Use them if you want to harvest your weed sooner. They work very well in hydroponic planting systems given the ease with which they dissolve in water and the ready availability. Chemical nutrients are also highly potent. Use them, and you will have near-explosive results.

Organic nutrients provide a natural way of growing weed. They are great for the environment since they hardly contain harmful chemicals. Organic chemicals work well for weed grown in soil. When used in hydroponic systems, they cause the growth of unwanted plants and clogging of the system. They promote the development of great weed aroma. They also promote faster and healthier growth.

What Effect Does It Have On The PH Of Your System?

Growing cannabis is a delicate balancing act. If you do not pay attention, you may end up with nutrient deficiencies. You may be using the right macro-nutrient ratios and yet still experience certain deficiencies and problems. Chances are you haven’t checked your water PH. With the wrong PH, the weed will find it difficult to absorb the nutrients you are feeding it with.

To encourage nutrient absorption, the water PH should be right. The right PH levels will vary depending on your chosen medium. In hydroponics, it should be between 5.5 and 6. For weed grown in soil, the PH should be 6 to 7. When grown in a hydroponic system, the weed needs proper balance. However, in soil, a little more acid is necessary. While some nutrients work automatically when it comes to maintaining the right PH, others necessitate the use of a PH tester. Using the tester, you will be able to know if you have the right values.

Will You Be Growing In Hydroponics Or Soil?

By and large, the nutrient needs for hydroponic and soil growing systems are different. Let’s talk about hydroponics. They are usually used to plant weed indoors. Instead of soil, weed is grown in water solutions. These systems are very efficient to the extent that they are suitable for growing weed indoors. Due to their use of water, most of the available nutrient powders and solutions are best suited for hydroponic systems. It doesn’t matter if you have chemical or organic nutrients.

However, if you choose to grow your weed in soil, these soluble nutrients can still work. The only problem with soil is that it may encourage the leakage of harmful chemicals into water systems. Thus, it is advisable to use organic nutrients in the soil. When used in hydroponic systems, organic nutrients tend to introduce the growth of other plants and clog the water system.


When choosing the nutrients for your weed, you need to know if you will grow it in soil or water. Once you are sure, you can pick a nutrient supplement that best serves your needs. Another thing to ponder about is the ratio of macro-nutrients in the package. That’s important, especially if you want to know the right nutrients to buy at a particular stage of growth. Follow the reviews discussed here together with the buying guide to know which weed nutrients will work for you the best.
