Why Hawaii's Top Growers Choose Black Cinder Over Red Cinder:

  • pH Neutral: Won't acidify your soil or stress plants (unlike red cinder)  
  • 30% Lighter: Easier to spread, less back-breaking labor  
  • Lasts Decades: Red cinder breaks down into dust; black cinder stays structural 
  • No Dust: Clean to work with (red cinder creates messy dust clouds)  
  • Perfect Mix: Blends ideally with Hawaiian Volcanic Organic Topsoil  

Key Benefits of Mixing Black Cinder with Hawaiian Volcanic Organic Top Soil

1. Superior Aeration

  • How It Works: Black Cinder’s porous structure integrates seamlessly with the nutrient-dense topsoil, creating space for airflow to reach plant roots.
  • Why It Matters: Improved aeration fosters healthy root development and reduces the risk of soil compaction, allowing plants to thrive.

2. Optimized Drainage

  • How It Works: When mixed with topsoil, Black Cinder helps water flow through the soil more efficiently, preventing waterlogging.
  • Why It Matters: The blend ensures a perfect balance, keeping plants hydrated without drowning their roots.

3. Enhanced Moisture Retention

  • How It Works: Black Cinder holds water within its pores and releases it gradually, complementing the nutrient-rich moisture-retaining properties of Hawaiian Volcanic Organic Top Soil.
  • Why It Matters: This blend is especially effective in dry climates or for plants requiring consistent hydration.

4. Mineral Enrichment

  • How It Works: Black Cinder is naturally infused with trace minerals that support plant growth and microbial activity, amplifying the benefits of the organic nutrients in the topsoil.
  • Why It Matters: The combination delivers a balanced and nutrient-rich environment for robust, healthy plants.

5. Long-Lasting Performance

  • How It Works: While topsoil provides organic matter for immediate nutrient delivery, Black Cinder’s durable structure ensures ongoing soil enhancement for years.
  • Why It Matters: Together, they form a sustainable, low-maintenance soil mix.

Leveling blocks
Size: 8.5" x 8.5", Color: Yellow
I used these on my first RV camping trip. I was on a not very level site and these worked well to level my camper. They worked so well I ordered another set. The handle is great at keeping the blocks together.

Very happy.
Size: 8.5" x 8.5", Color: Yellow
Bought these at the start of our camping season. I really prefer these to the ones you drive up on that are like a ramp. Besides leaving out under your wheels they can be used for your stabilizer feet as well or your hitch. Quality is great I have not had one crack, I was worried these would be too big to pull my tires over easily but that wasn’t a problem at all. The size allows you to group them together like legos to do what you need to get level. They come in a bundle with a handle that secures them all together in a nice lightweight block that’s easy to store. I actually bought a second set for my fifth wheel after buying the first set. I got them both on sale and am very very happy with them.

Great alternative to wood blocks
Size: 17" x 8.5", Color: Gray, Size: 17" x 8.5", Color: Gray
So I’ve used wood over the years to level out my Class A RV’s and even with the wood sealed, there is always one side that takes a beating. I figured I would try these Camco rectangular leveling blocks and was very surprised at their strength. I’ve only used them twice, but both times the RV rolled right up with no issues. The RV sitting on those blocks in the picture is a 40’ Tiffin diesel pusher. My only issue is the dual wheel base for this big RV, is too wide to use the blocks perpendicular to the wheels, so I had to use 3 blocks parallel (see pics) for each wheel, which required me to purchase two sets. Most sites I setup up at fairly level, but this just provides that little extra height if needed.
