ANTMART Grid Black 200×200 mm: controlled space for a growing colony

Grid Black is a square formicarium with modular living sections, a separate high-walled arena, and distributed hydration. Variant A combines a PETG body with G-23 gypsum covering part of the chamber floor. This arrangement is designed to introduce nest space gradually while maintaining both moister and drier areas.

Five separately managed hydration zones

The nest contains five autonomous sections. Instead of hydrating every chamber to the same degree, the keeper can work with selected areas. Removable dividers support staged expansion: a small colony receives only the space it currently needs, and further sections can be opened as its population develops.

This approach makes nest volume easier to manage and reduces the likelihood that distant unused rooms will become refuse chambers. It also allows some areas to remain dry, which is relevant to seed-storing species. The design cannot by itself eliminate mold, odor, or mites, however. Outcomes still depend on ventilation, actual hydration practice, leftover food, and routine cleaning.

PETG with partial G-23 gypsum flooring

The main farm structure is made from PETG. Its listed properties include Food Grade status, biological neutrality, and no styrene emission. Variant A is not a fully gypsum model: G-23 gypsum covers part of the floor and distributes moisture, while other sections can be kept comparatively dry.

This combination is intended to create a gradient rather than a uniformly wet nest. Ants can position their brood among chambers offering different conditions. The precise placement of eggs, larvae, and cocoons will vary with species and current microclimate, so colony behavior should be used as an observation cue rather than treated as a guaranteed pattern.

Extra chamber height

The stated standard chamber height is 15 mm, reaching up to 21 mm in selected sections. This additional vertical clearance is intended to accommodate large workers and queens that may be constrained by shallow passages. Camponotus japonicus and Camponotus fedtschenkoi are cited in the source as examples of larger ants that can benefit from the space.

Height alone does not establish compatibility. Before introducing a colony, also compare passage width, exit dimensions, the species’ moisture requirements, family size, and the ability of workers to move safely through all connecting components.

Arena and mechanical components

The 80 mm-high arena is made from cast German acrylic. It provides an accessible area for feeding, observation, and waste removal. Nylon screws are used because they do not rust when exposed to moisture. Mechanical gates at the entrances allow passages to be closed during maintenance or when changing the active nest configuration.

The source claims complete escape resistance, but this cannot be assessed without testing and exact gap measurements. Before housing ants, particularly a small species, inspect the joints, gates, ventilation parts, and connection ports under practical conditions.

Dimensions and stated capacity

The model measures 200×200 mm. Its removable dividers mean that a young colony does not need access to the entire internal volume from the beginning. The manufacturer states an estimated 2–3 years of active colony development and a maximum capacity of up to 3,000 Messor structor individuals. These figures are not universal: growth rate, worker size, and use of available chambers vary by species and colony.

The input also presents the farm as a 3–5-year investment, but it provides no supporting service conditions or warranty. Actual lifespan will depend on maintenance, load, heat, moisture exposure, and mechanical handling.

Species named as compatible

The source recommends Grid Black for:

• Camponotus nicobarensis;
• Camponotus pseudoirritans;
• Camponotus maculatus subnudus;
• Myrmicaria brunnea.

Camponotus japonicus and Camponotus fedtschenkoi are additionally mentioned as examples of large ants suited to taller chambers. This list does not replace a husbandry review for the intended species. Since Grid Black is a partially gypsum farm, its five-zone hydration system must still be matched to the colony’s specific moisture requirements.

FAQ

Does the design help manage mold and odor?

PETG does not absorb moisture like wood-based materials, and the separate zones allow some chambers to remain dry. This can make moisture and seed-storage management easier, but mold and odor still require appropriate ventilation, cleaning, and control of leftover food.

Should every section be opened immediately?

No. The removable dividers are intended for gradual expansion. A new section should be introduced when the colony has made substantial use of the space already available.

Is the farm suitable for very small ants?

An anti-escape arrangement is claimed, but exact clearances are not supplied. Check every joint, ventilation component, gate, and port before moving in a small species.

What defines variant A?

It is a combined construction rather than a fully gypsum nest. The PETG body is supplemented by G-23 gypsum over part of the floor, allowing the keeper to establish areas with different moisture levels.
