Tinyroots Bonsai Training Pots with Humidity Trays - Built in Mesh, 6 Inch and 8 Inch Combo Pack, Set of 6 Review (2026)

Who this combo pack fits

This set pairs three 6 inch pots with three 8 inch pots, each with a matching humidity tray, so it suits someone who is potting up several trees at once and wants a uniform look across two common training sizes rather than shopping for each size separately. It works well for a grower moving a handful of seedlings or young stock from nursery pots into their first proper training containers, since the mixed sizing covers both smaller material and slightly more developed trees in a single purchase. Someone with a single tree that needs one specific size, or a collector who already has plenty of 6 inch pots and only wants more 8 inch ones, will get less value from the fixed 3 and 3 split than from buying a single size pack instead.

Construction and what is included

Each pot is made from a shatter resistant poly resin plastic described by the manufacturer as durable in freezing and hot conditions, with a built in mesh insert over the drainage holes so soil stays in the pot while water and excess fines pass through. A matching humidity tray comes with each pot, sized to catch runoff and hold a shallow reservoir of water that raises local humidity around the root zone, which is useful for trees kept indoors or in dry climates. The pots stack for storage or transport when empty, and the poly resin construction keeps the whole six piece set light enough to move around a bench without strain, though that same light plastic build is less substantial than glazed ceramic or mica training pots.

Repotting and everyday use

In practice, the built in mesh saves a step during repotting since there is no separate screen to cut and wire in place, which speeds up the process when working through several trees in one session. The trays help maintain moisture around the pot base between waterings, which matters most for trees that dry out quickly in small volumes of bonsai soil, though they still need to be emptied or refreshed periodically to avoid stagnant water and pests. Because the pots are plastic rather than fired clay, they warm and cool faster than ceramic, so growers in hot climates may want to keep them out of intense afternoon sun to protect the root ball from overheating.

How the sizing trade-off compares with buying single sizes

Against buying six of one size, such as a straight set of 6 inch or 8 inch pots, this combo gives less flexibility if your collection is mostly one stage of development, since you are locked into a 3 and 3 split rather than choosing the ratio yourself. Compared with heavier ceramic or mica training pots from brands like Bonsaiboy, this poly resin set is lighter and less expensive per pot, but offers less thermal mass and a shorter expected lifespan under UV exposure and repeated freeze thaw cycles outdoors. For someone specifically starting a new collection across a couple of size classes at once, the combo format still saves the hassle of two separate orders even with that fixed size split.

Verdict and who should look elsewhere

This set is a practical, no frills way to outfit a small bonsai bench with two common training pot sizes and matching humidity trays in one purchase, and the built in mesh is a genuine time saver at repotting time. Growers who need every pot in one size, or who want a more durable material than poly resin for long term outdoor display, should look at single size sets or ceramic training pots instead. For anyone assembling starter stock across a couple of sizes without wanting to place two separate orders, this combo pack does the job well.
