Cloning Cart Calculator

Calculate How Many Cloning Carts You Need

When planning a propagation cycle, it is important to make sure you have enough tray and cart capacity before taking cuttings.

By entering the total number of clones required, the tray cell count, and the number of trays that fit on each cloning cart, the calculator can estimate:

• Total number of propagation trays required
• Total cloning capacity per cart
• Number of cloning carts required
• Remaining unused tray capacity
• Overall propagation capacity for your setup

This makes it easier to plan your propagation room and ensure you have enough space for upcoming cloning cycles.

How the Calculation Works

The calculator first determines how many trays are required based on your total number of clones and the number of cells available in each tray.

The basic calculation is:

Because you cannot use a fraction of a tray, the result should always be rounded up to the next complete tray.

For example, if you need 1,000 clones and are using 72-cell propagation trays:

1,000 / 72 = 13.89 trays

You would therefore need:

14 propagation trays

The calculator then determines how many cloning carts are needed based on the number of trays each cart can hold.

Again, the result should always be rounded up to the next complete cart.

For example, if each cloning cart can hold 16 trays:

14 trays / 16 trays per cart = 0.88 cart

You would therefore need:

1 cloning cart

Why Cloning Cart Planning Matters

Proper cloning cart planning helps support a more organized and efficient propagation process. Having enough tray and cart capacity before starting a cloning cycle can help you:

• Avoid running out of propagation space
• Better organize cloning batches
• Improve propagation-room workflow
• Plan tray and insert requirements
• Maximize available cart space
• Improve scheduling between propagation cycles
• Estimate future cloning capacity
• Support larger commercial production programs

For larger facilities, even small differences in tray capacity can have a major impact on the number of carts required.

Tray Cell Count

Propagation trays are available in a variety of cell configurations, and the number of clones that can be produced per tray depends on the tray or insert being used.

Common tray formats may include:

• 50-cell trays
• 72-cell trays
• 78-cell trays
• 98-cell trays
• 104-cell trays
• 128-cell trays
• Other commercial propagation formats

A higher cell count increases the number of clones that can be placed on each tray, while larger cells may provide more space for root development.

The correct tray configuration will depend on your crop, propagation method, rooting time, and production requirements.

Cloning Cart Capacity

The total capacity of a cloning cart depends on the number of propagation trays that can be placed on each shelf and the total number of usable shelves.

The calculator uses:

For example:

If your tray contains 72 cells and your cloning cart holds 16 trays:

72 x 16 = 1,152 clones per cart

This means one fully loaded cart can support up to approximately 1,152 cloning sites, assuming every tray cell is used.

Plan for Extra Clones

Commercial growers often produce more clones than the exact number required for planting.

This additional propagation capacity can help account for:

• Unrooted cuttings
• Weak or uneven clones
• Transplant losses
• Plant selection
• Production scheduling changes

If your operation uses an overage percentage, you may want to calculate your total cloning requirement before determining tray and cart quantities.

For example, if you need 1,000 finished clones and plan for a 10% overage:

1,000 x 1.10 = 1,100 clones

The calculator can then use 1,100 clones as the total propagation requirement.

Estimate Your Propagation Capacity

Once you know your total clone requirement, tray cell count, and number of trays per cart, the Cloning Cart Calculator can help determine the number of carts required for your propagation program.

This can help you prepare your cloning area, plan equipment purchases, and better coordinate propagation schedules before each production cycle.

Important Note

This calculator provides an estimate only. Actual cloning capacity may vary depending on tray dimensions, cart configuration, shelf spacing, propagation equipment, clone spacing, crop requirements, and facility procedures.

Always confirm the actual number of trays that can safely fit on your cloning cart and the usable cell count of your selected propagation tray before finalizing your production plan.
