How to Use SM-90 for Cannabis Growing

If you’re serious about growing top-tier herb, you’ve probably heard whispers about SM-90. This versatile product is like the Swiss Army knife for your grow setup, tackling everything from root health to pest control. But what exactly is SM-90, and how can it help your cannabis (or as some like to call it, green, bud, or Mary Jane) thrive? Let’s break it down.

Sm 90

What Is SM-90? 🌱

SM-90 is a plant additive made from natural plant oils, including coriander oil. It’s designed to promote healthy roots, boost plant vigor, and even act as a preventative measure against pests and fungi. Whether you’re growing indoors, outdoors, in soil, or hydro, SM-90 can elevate your grow game.

Think of it as a multi-tool: it fights pests, keeps your roots pristine, and improves nutrient uptake all at once. And the best part? It’s natural and biodegradable, which means it’s safe for your plants and the planet.

If you’re setting up your first grow, understanding how to grow weed indoors can help you maximize yields and create the perfect environment for your plants.


Why Use SM-90 on Cannabis? 💨

Growing fire weed isn’t just about light and nutrients—it’s about maintaining a healthy, balanced environment for your plants. That’s where SM-90 shines. Here’s why growers love it:

  • Root Health: It prevents nasty issues like root rot and keeps your roots looking white and thriving.
  • Pest Control: SM-90 can deter pests like aphids and spider mites without harsh chemicals.
  • Fungal Prevention: Got mildew problems? SM-90 can help keep it in check.
  • Improved Nutrient Uptake: Healthy roots mean your plants can soak up nutrients more efficiently, leading to bigger, better buds.

How to Use SM-90 in Your Grow 🌿

Ready to make SM-90 part of your cannabis care routine? Here’s how to use it effectively:

1. As a Root Zone Treatment 🌱

  • Dilution: Mix SM-90 with water at a ratio of 1:5 or as directed on the bottle.
  • Application: Water your plants as you normally would, ensuring the mixture reaches the root zone.
  • Frequency: Apply every 7–14 days to keep your roots clean and healthy.

2. As a Foliar Spray 💧

  • Dilution: Combine SM-90 and water at a 1:5 ratio.
  • Application: Use a spray bottle to coat the leaves, focusing on the undersides where pests like to hang out.
  • Timing: Spray during the early morning or late evening to avoid burning your leaves under direct light.

3. In Hydroponics 💦

  • Mixing: Add SM-90 directly to your nutrient solution at a ratio of 2–3 ml per gallon.
  • Monitor: Keep an eye on your system to ensure there’s no foam buildup.

Tips for Getting the Most Out of SM-90 🌟

  • Don’t Overdo It: While SM-90 is awesome, using too much can overwhelm your plants. Stick to recommended doses.
  • Use It Early: SM-90 works best as a preventative tool, so start using it before problems appear.
  • Combine It Wisely: SM-90 plays well with most nutrient and pest control regimens, but always test compatibility before mixing products.

Can You Use SM-90 During Flowering? 🌸

Technically, yes, but it’s best to be cautious. Many growers avoid foliar sprays or additives late in the flowering stage to preserve the flavor and aroma of their buds. If you do use SM-90 during flowering, stick to root zone treatments and stop applications at least 2–3 weeks before harvest.


Benefits of SM-90 for Your Buds 🌿💨

When you incorporate SM-90 into your grow, you’re setting the stage for success. Here’s what you can expect:

  • Vibrant Plants: Healthier roots and leaves mean your plants stay green and happy.
  • Stronger Defense: Fewer pests and diseases to stress your crop.
  • Bigger Yields: Optimized root health and nutrient absorption mean denser nugs at harvest.

Are There Any Downsides to SM-90? ❌

While SM-90 is a grower’s favorite, there are a couple of things to keep in mind:

Not Always Available: Some regions have restrictions on SM-90, so you might need to check your local suppliers.

Foaming in Hydroponics: It can sometimes create foam in hydro setups, so watch your reservoir carefully.
