Why Happy Frog Soil is the Best Choice for Growing Cannabis

In case you couldn’t tell by the title, I love Happy Frog Soil.

I’ve tried a lot of different soils in different growing conditions and the soil that produces the highest yields with the best nutrient blend is Happy Frog.

If you’re having any issues with your grows or just aren’t happy with your yields, then potting soil is the first place to troubleshoot.

In this review I’ll talk about some of the things to look out for when buying a soil for growing weed and why Happy Frog is the best of the best.

What Makes Happy Frog Soil So Good?

If you want to see some of my other favorite soils for growing weed, you can check that out here.

But what separates Happy Frog apart from the rest comes down to 3 things.

  1. Happy Frog has a balanced N-P-K (Nitrogen, Phosphorus, Potassium) blend that’s specially formulated for growing cannabis.
  2. Happy Frog soil has some organic additions like bat guano, earthworm castings, crab meal, and fish emulsion which create a healthy environment for your plants.
  3.  It has a perfectly tuned pH so you don’t have to mess with anything and your plant will thrive without needing additional fertilizers.
There are a lot of other things to love about Happy Frog, but if you want to know why it grows the dankest buds, these 3 factors are the most important things to know.
One thing worth mentioning about Fox Farm Happy Frog soil is that it’s very beginner friendly.
It’s common for beginners to over-water their plants but this is fixed with Happy Frog soil because it’s aerated very well and promotes drainage so your plant’s roots don’t drown.

I’ll go into more detail on these 3 points and give some additional info on what to look for if you’re comparing Happy Frog to other choices like Fox Farms Ocean Trio (another one of my favorite soils).

Happy Frog Soil N-P-K Ratio and Why It's So Good

If you’ve bought soil before, you probably noticed some numbers on the front of the bag that looked like “5-20-15”. This is the N-P-K ratio which is shorthand for Nitrogen-Phosphorus-Potassium.

Don’t ask why K is potassium. I didn’t invent the period table of elements so blame that one on the scientists.

Different plants need different ratios of N-P-K to thrive. If you have too much of one element, it can cause nutrient deficiencies or excesses int he plant and stunt it’s growth.

This infographic on the N-P-K ratios from Autoflowerseedshop.com gives a good overview of what each nutrient does.

Nitrogen is primarily used in the early stages of the marijuana plant’s growth when it’s rapidly expanding upward and outward with large fan leaves. 

Phosphorus is primarily used in the flowering stage when the buds are being formed and increasing in size.

Potassium is used during the entire lifecycle of the plant and helps reinforce the cell walls and make the plant more resistant to insects and diseases like mold.

Some soils, like Miracle-Gro which you’d find at Walmart, will straight up kill your weed plants. This is because the N-P-K ratio in Miracle-Gro isn’t meant for cannabis plants and it uses an extended release formula.

Other cannabis potting soils like Fox Farms Ocean Trio, which can be a fantastic soil, are higher in Nitrogen and can cause nutrient burn where the tips of your leaves will get chemical burns and start to die.

Happy Frog has all the nutrients your plants need in the perfect balance so no nutrient is too strong or overpowering which can kill your plants.

Bat Guano, Earthworms and Fish Emulsions...oh my

Having the correct N-P-K ratio isn’t the whole story.

It’s a good starting point and an essential element to having healthy soil, but to have exceptionally high quality soil, you need to add something extra to it.

That’s what FoxFarm did by adding these additional ingredients. 

These ingredients promote a healthy microbiological environment so healthy bacteria and fungi can thrive and help contribute to the growth of your plants roots and the uptake of nutrients from the soil.

Here’s a run down of some of the additional organic materials FoxFarm adds to Happy Frog Soil:

  • Bat guano (aka poop)
  • Earthworm castings
  • Fish emulsions
  • Humic acid
  • Crab meal
  • Sphagnum peat moss

Each of these additions create the perfect environment for your cannabis plant’s roots which means the plant will get more nutrients and have more explosive growth. This is commonly called ‘root efficiency’ and is just a measure of how well the roots are able to uptake nutrients.

This is especially important in the flowering phase when your plant is developing buds and coming to maturity.

The Perfectly Tuned pH of Happy Frog Soil

The final factor that impacts your plants nutrient uptake and overall health is pH.

No matter what nutrients are in the potting soil, if your pH isn’t in the right zone, the nutrients won’t make it into the plant.

Here’s a handy guide for what nutrients are absorbed after different pH ranges.

This nutrient uptake chart from skunkgrow.com shows the optimal ranges for nutrient absorption in cannabis plants.

The pH of Happy Frog potting soil is in the 6.0-7.0 range so it’s good to go as soon as you open it up.

You should always monitor the pH of your soil, especially if you start to see issues like your leaves changing colors.

Out of all the soils I’ve used, Happy Frog has always been the easiest to work with. It just ‘works’ and usually doesn’t require any adjustments, even when I hit the flowering stage and the phosphorus usage cranks way up.

Fox Farms has perfectly tuned the ratio of nutrients so you have just enough nitrogen to make it through the vegetative stage without having too much which can cause nute burn.

The pH is consistently in the Goldilocks zone so you don’t have to worry about it or adjust unless you want to.

Wrap Up

What are you waiting for?

Go buy a bag of Happy Frog Potting Soil.

This stuff is amazing and it works really well. 

If you’ve been having issues with other soils or you’re trying to increase your yield, this is what you’ve been looking for.

I fought with my plants and added so many fertilizers and balancing agents until I switched to Happy Frog.

Once I made the switch I never looked back and I started getting 4+ oz per plant.

Try this soil. You’ll love it and your plants will love it even more.
