The Ultimate Bootstrap Farmer Sizing & Modular Guide for NZ Growers
The Ultimate Bootstrap Farmer Sizing & Modular Guide for NZ Growers
Choosing the right tray configuration is the difference between an awkward, messy grow space and a streamlined, high yield setup. Every genuine Bootstrap Farmer tray is injection molded from food safe, BPA free PP #5 plastic, built to a 1.8mm–2.0mm commercial thickness, and UV-stabilized for long-term durability.
A modular microgreen tray system uses exact dimensions where smaller configurations (like 1010 or 5x5 trays) fit perfectly inside a standard 1020 tray base. This allows New Zealand commercial vertical farms and backyard growers to mix, match, and bottom water multiple crop varieties simultaneously on a single shelf.
Below is the complete breakdown of how each size works, what it’s best for, and how to build the most efficient growing system possible.
Why Modularity Matters for NZ Growers
New Zealand growers often work with limited indoor space, higher media costs, and variable seasonal light. A modular tray system lets you:
- Run multiple crop varieties on a single shelf
- Reduce wasted soil and jute mats
- Test new seeds without sacrificing full trays
- Bottom water everything from one reservoir
- Scale up or down instantly without reconfiguring your grow room
1. The 1020 Series (The Foundation)
The classic 10" x 20" footprint is the gold standard of commercial vertical farming and market gardening.
1020 Deep Trays (2.5" / 6.3 cm Depth)
- Best Used For: Heavy wheatgrass crops, deep rooted microgreens (sunflower, peas), and as the ultimate leak proof bottom reservoir.
- The Highlight: Holds massive weight without flexing. Ideal for NZ growers who move trays frequently or run stacked shelving.
1020 Shallow Trays (1.25" / 3.2 cm Depth)
- Best Used For: Fast growing microgreens like radish, broccoli, and salad mixes.
- The Highlight: Increased airflow reduces mold risk and saves up to 30% on grow media per harvest. You can view the full range here: Bootstrap Farmer 1020 Microgreen Trays.

2. The 1010 Series (The Half-Size Split)
Exactly half the size of a standard 1020, allowing you to split crops without losing shelf efficiency. Two 1010 trays fit perfectly inside one 1020 tray base.
1010 Deep Trays (2.5" / 6.3 cm Depth)
- Best Used For: Small scale sunflowers, restaurant delivery, and deep root propagation.
- The Highlight: All the depth of a 1020 at half the footprint, perfect for tight NZ grow shelves.
1010 Shallow Trays (1.25" / 3.2 cm Depth)
- Best Used For: Staggered microgreen plantings and weekly home harvests.
- The Highlight: Grow two completely different varieties inside a single 1020 footprint using the space saving Bootstrap Farmer 1010 Shallow Tray setup.

3. The 5x5 Series (The Small-Batch Modules)
The ultimate micro-modular system. Eight 5x5 trays fit inside a 1020.
5x5 Deep Trays (2.5" / 6.3 cm Depth)
- Best Used For: Live chef sales, herbal micro-crops, tasting packs.
- The Highlight: Chefs love receiving a living 5x5 block they can cut fresh at the line.
5x5 Shallow Trays (1.25" / 3.2 cm Depth)
- Best Used For: Boutique varieties and seed batch testing.
- The Highlight: If a batch fails, you lose only a tiny fraction of your shelf space with Bootstrap Farmer 5x5 Shallow Trays.

4. The Heavy-Duty Plug & Seedling Series
Engineered for market gardeners, orchardists, and serious propagation where root health determines transplant success.
4 Cell Inserts (Heavy-Duty Air Pruning)
- Best Used For: Larger vegetable starts that resent root bundling (cucumbers, zucchini, pumpkins, melons, and large tomato clones). Eight 4-cell inserts fit perfectly inside a single 1020 tray (32 cells total).
- The Highlight: Features wide open bottom drainage and side slits. It guides large taproots downward to air-prune naturally, completely eliminating root bound circling and transplant shock for sensitive crops.
6 Cell Inserts (Heavy-Duty)
- Best Used For: Standard market garden vegetable plugs (tomatoes, brassicas, peppers) and robust herb starters. Twelve 6-cell inserts fit inside a 1020 (72 cells total).
- The Highlight: Unlike flimsy, brittle garden centre cell packs, these never collapse or tear. You can safely push root plugs out from the bottom hundreds of times without the plastic cracking using our Bootstrap Farmer 6-Cell Inserts.
72 Cell Air Pruning Trays
- Best Used For: Native trees, forestry, orchard stocks, and deep-rooted field crops.
- The Highlight: A single standalone injection molded unit. Vertical open slots = natural air pruning, forcing a massive web of fibrous side roots and explosive growth once transplanted out into NZ soil.

Frequently Asked Questions
How do Bootstrap Farmer trays fit together?
The system is based on the 1020 footprint. Two 1010 trays, eight 5x5 trays, eight 4-cell or twelve 6-cell inserts fit perfectly inside a 1020, enabling modular bottom watering.
Should I use deep or shallow trays?
Shallow trays suit most microgreens. Deep trays are for sunflower, peas, and wheatgrass.
What makes an air pruning tray different?
Air pruning trays guide roots downward and prune tips naturally using air exposure, preventing root circling and creating a highly branched, fibrous root system.
Are Bootstrap Farmer trays food-safe?
Yes. BPA-free, food-safe, UV-stabilized PP #5 plastic.
Do they work with bottom watering?
Yes. The entire system is engineered for bottom watering efficiency.
