THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are managing large-scale bulk storage bins because you need a way to protect your harvest without manually rotating dozens of smaller packs.
  • You are upgrading your curing and storage workflow because you need to keep humidity stable across larger containers to prevent mold in the center of your bin.

  • We recommend this size for any airtight tote over 20 gallons because the surface area is finally large enough to actually regulate the surrounding air.
  • The cardboard sleeve is useful during the initial packing phase, but removing it helps the pack respond faster if your environment is especially dry.

  • Processors who switched to this 320g size say they stopped finding dry spots in the corners of their deep storage totes.
  • Growers who used to struggle with humidity spikes in large bins report that these packs leveled out their equilibrium within the first 48 hours.

Boveda 2-Way Humidity Control Pack 62% RH - 320g Individually Wrapped

Storing pounds of harvest instead of ounces changes the stakes — a single dry pocket or humid corner in a bin can wreck an entire batch of trim or flower. The Boveda 320g pack is built for exactly that scale, protecting up to 5 pounds (2.5kg) of material in one large-format, individually wrapped pack. It's the same patented 2-way humidity control technology found in smaller Boveda 67g packs, scaled up so growers and processors can protect bulk storage bins and totes without lining them with a dozen small packets.

Because the 320g is sold and wrapped individually rather than in a multi-pack case, it's built to sit inside large airtight totes or bins for the full length of a storage cycle, restoring and maintaining 62% RH to form the same protective monolayer over trichomes that smaller Boveda packs create in personal CVault storage jars. The factory-sealed overwrap keeps the pack at full strength in storage until it's opened, and the outer cardboard box adds structural protection for handling large containers — though it can be removed if the pack needs to fit into a tighter space, as long as the packet itself isn't pinched or crimped when the lid closes.

How To Use

Remove the plastic overwrap and place the unwrapped Boveda directly into your storage bin or tote along with your material. Make sure the container is airtight so the pack can work as efficiently as possible — no activation is needed, and it's safe to touch your material directly.

Keep the Size 320 in its outer cardboard box for added protection and stability during handling. If it doesn't fit your container as-is, you can remove it from the box, just be careful not to pinch or crimp the packet when closing the lid. Do not mix Boveda RH levels or use it alongside other humidification products in the same container, as this reduces efficiency for both.

Frequently Asked Questions

How much material does one Size 320 pack protect? +

A single Size 320 pack is designed to protect up to 5 pounds (2.5kg) of material, making it ideal for large airtight storage bins or totes like the 5lb CVault.

Do I need to activate the Boveda pack before use? +

No. Once you remove the plastic overwrap and place it in your container, it works automatically — releasing or absorbing moisture as needed with no activation required.

Can I remove the Size 320 from its cardboard box? +

Yes, if it doesn't fit your container with the box on. Just make sure the packet itself isn't pinched or crimped when you close the container's lid, since damage to the packet can affect performance.

How do I know when to replace the pack? +

Do a touch test — if the pack still has soft spots among some hardened areas, it's still working. If it feels completely rigid all the way through, it's expired and should be replaced.

Can I mix Boveda with other humidity control products? +

No. Mixing different Boveda RH levels or combining Boveda with other humidification products in the same container will counteract each other and reduce overall effectiveness.

How long does the Size 320 pack last? +

In an airtight container, it typically lasts 2 to 4 months depending on how often the container is opened and the material's moisture content. Unopened, it stays effective for up to 2 years.

Is 62% RH the right choice for my situation? +

62% RH suits humid climates, stickier material preference, and long-term storage where maintaining water weight matters. The right RH ultimately comes down to your climate and smoking preference.
