can you grow weed without adding nutrients

Cannabis plants need different amounts of these nutrients throughout the different stages of growth: more nitrogen during vegetative growth, and more phosphorus and potassium during flower for bud production—also called “bloom” nutrients.


A cannabis plant needs many nutrients, and pulls these from the soil. Left on its own, with good soil, plenty of light and water, and a temperate environment, a weed plant will grow fine, but nutrients will help the plant thrive and grow healthy and strong.

What are cannabis nutrients?

Giving weed plants the proper amount of nutrients requires careful monitoring. Many growers start at a solution dose lower than recommended and work their way up until plants respond optimally. Too little nutrients and the plants will have stunted growth, while too many can lead to nutrient burn and lockout.

That might work if you have good soil and the right strain of plant, but most growers, regardless of where they’re planting, fortify the soil a few times throughout the process to ensure the cannabis always has what it needs.

What Nutrients are we Talking About?

If you’re heavily into organic growing, or you’re just looking for a low-maintenance “just add water” way to grow some cannabis, you may have thought about growing without nutrients.

Make your own Super Soil

You can’t just mix together a few pounds of this stuff—this is a full-on ecosystem that will take a lot of ingredients, time (you have to let it sit for at least 30 days), and effort to mix properly.
