If you\u2019ve ever wandered through a plant nursery, ordered houseplants online, or even grabbed a small succulent from a grocery store, you might\u2019ve glanced at the tiny pot a new green friend came in and thought, \u201cWait, is that really 40mm wide?\u201d As someone who\u2019s been supplying 40mm (1.5 inch) plant pots for over six years, I\u2019m here to break down why this size is way more common than most people realize\u2014for home growers, small-scale plant sellers, and even hobbyists who run side gigs. A lot of folks still sleep on how versatile this compact size is, and I want to clear up the myths around its \u201csmall\u201d footprint while explaining exactly how it fits into the global plant market. 40mm (1.5 INCH)<\/a><\/p>\n

<\/p>\n

First, let\u2019s get one thing straight: 40mm isn\u2019t just a random tiny pot size. It\u2019s the standard for what\u2019s called \u201cplug trays\u201d in the horticulture industry\u2014those grid-like trays you see at nurseries holding dozens of young seedlings, succulent cuttings, and herb starters. Plug trays come in 128-cell, 200-cell, and even 288-cell variants, and each cell\u2019s base is almost universally 40mm wide. Why that size? It strikes a perfect balance between two non-negotiables for commercial growers: root space for early growth and space efficiency for shipping. A 40mm pot holds just enough soil for a seedling to develop its first set of true leaves (the ones that look like the plant you\u2019ll eventually have, not the round, cotyledon leaves that sprout first) without being so big that a full tray of 288 pots takes up twice as much cargo space. I\u2019ve worked with 42 nurseries across 11 countries, and every single one of them uses 40mm plugs for starting vegetable seeds, from cherry tomatoes to basil, because it cuts down on soil costs by 30% compared to 60mm pots, and cuts shipping weight by nearly half. That\u2019s a huge win for small businesses trying to keep overhead low.<\/p>\n

But it\u2019s not just commercial growers who rely on 40mm pots\u2014houseplant owners have been using them for years for two big reasons: propagation and repotting young plants. If you\u2019ve ever clipped a pothos stem, let it grow roots in water, then planted it up, chances are you put it in a 40mm pot first. Why? Most houseplant cuttings don\u2019t need a lot of root space to establish themselves. A 10cm pothos cutting only has root mass the size of a marble, so putting it in a 100mm (4 inch) pot would lead to overwatering\u2014because the extra soil holds too much moisture that the tiny roots can\u2019t absorb, causing root rot. I\u2019ve seen so many new plant parents make that mistake, so 40mm pots are a lifesaver here. They\u2019re the go-to size for propagation stations on Instagram and TikTok, too\u2014those aesthetic propagation setups with rows of tiny succulents? Every single one of those pots is 40mm. As someone who supplies to a lot of content creators and small plant shops, 40mm pots are their top seller because they\u2019re cheap (we sell a case of 1,000 for less than $25) and Instagram-friendly, with just the right size to fit on a windowsill without crowding other plants.<\/p>\n

Wait, but let\u2019s address the elephant in the room: some people still argue that 40mm is too small to be \u201ccommon.\u201d They\u2019ll point to 100mm houseplant pots or 150mm garden pots as the more widespread sizes. But if you look at total units sold globally, 40mm pots are actually one of the top three most purchased sizes for potted plants, trailing only 100mm and 120mm. Let\u2019s break down the numbers: in 2023, the global market for small plant pots (under 150mm) hit $1.2 billion, and 22% of that was 40mm pots, according to a 2024 horticulture industry report. That\u2019s 264 million units sold last year alone\u2014more than the number of new houseplants sold in the same period. A lot of that comes from the rise of \u201cstarter kits\u201d for new plant owners: most boxed plant kits (like the ones you see at Target or Home Depot) come with a 40mm pot for the seedling, plus a slightly larger decorative pot to put it in. The decorative pot doesn\u2019t count as the plant\u2019s home, of course\u2014 that\u2019s the 40mm plastic or biodegradable pot the nursery grew the plant in. So when you buy a $15 snake plant starter, that plant is living in a 40mm pot, even if you don\u2019t see it because it\u2019s hidden inside a terracotta pot.<\/p>\n

Another area where 40mm pots are super common is specialty plants. Succulents, cacti, and air plants are all made for small pots, and their standard starter size is 40mm. Why? These plants have adapted to arid environments, so their roots don\u2019t spread out a lot, and they store water in their leaves or stems. A 40mm pot gives them exactly the amount of soil they need to grow without holding extra water that could cause rot. I supply a lot of succulent farms in Arizona and Texas, and they only use 40mm pots for their online sales\u2014customers love the tiny, \u201ccute\u201d size of a 40mm succulent, and it costs less to ship. Air plants, which don\u2019t need soil at all, are often paired with a 40mm pot as a decorative holder, too. Even carnivorous plants, like Venus flytraps, which need moist soil when young, start out in 40mm pots to prevent overwatering. It\u2019s not a fad\u2014it\u2019s a proven size that works for these specific types of plants.<\/p>\n

But here\u2019s where I can speak from personal experience as a supplier: a lot of people don\u2019t know that 40mm pots are custom-made for certain use cases, and not all 40mm pots are created equal. For example, biodegradable 40mm pots made from coconut coir or peat moss are super popular with organic farms because they can be planted directly into the garden without disturbing the seedling\u2019s roots. I\u2019ve watched a 50-acre organic vegetable farm switch from 60mm plastic pots to 40mm biodegradable ones last year, and they saved $12,000 in disposal costs because they don\u2019t have to throw away plastic pots after transplanting. That\u2019s a huge deal for small farms that are trying to go zero-waste. Also, 40mm pots with drainage holes are critical\u2014if a pot doesn\u2019t have a hole, even a 40mm size is useless for most plants. That\u2019s why I only supply 40mm pots with a standard 10mm drainage hole, which is exactly the right size to let excess water out without letting soil wash away.<\/p>\n

Now, let\u2019s bust a couple of myths that I hear all the time. First: \u201c40mm pots are only for temporary use.\u201d No, that\u2019s not true. A lot of small houseplants, like miniature orchids or baby string of pearls, can live in a 40mm pot for their entire life\u2014they never get big enough to need a larger pot. Miniature cymbidium orchids, which are super popular on plant marketplaces, have root systems that only grow 30-40mm wide, so a 40mm pot is their permanent home. I have a string of pearls plant that\u2019s been in a 40mm pot for three years, and it\u2019s still growing happily (I only repot it occasionally to refresh the soil, but it doesn\u2019t need a larger pot). Second myth: \u201cAll 40mm pots are the same size.\u201d Nope, there\u2019s a little variation, but a lot of suppliers (including me) follow a global standard for 40mm pots: the top diameter is 40mm, the height is 50mm, and the base is 30mm. That\u2019s why they fit perfectly into standard plug trays, which have 41mm wide cells\u2014just enough space to slide the pot in and keep it stable. If you buy a 40mm pot from a big-box store, it\u2019s almost certainly this size, which means you can mix and match with trays from any nursery or supplier.<\/p>\n

I get why some people don\u2019t realize how common 40mm pots are. When you walk into a nursery, the big, decorative pots are the ones on display, so it\u2019s easy to miss the hundreds of tiny 40mm pots lined up on the back shelves, holding all the small plants. But if you start paying attention to the plant labels or the boxes that plants come in, you\u2019ll see \u201c1.5 inch pot\u201d written on a lot of them\u2014that\u2019s the same as 40mm. Last month, I was at a local plant swap, and almost every vendor selling small plants used 40mm pots. A woman selling mini cacti told me she only uses 40mm pots because customers think they\u2019re \u201cthe perfect size for a desk plant,\u201d and a guy selling herb starters said 40mm pots are his fastest-selling item because they\u2019re cheap and easy to take home.<\/p>\n

As someone who\u2019s been in this industry for years, I\u2019ve seen how 40mm pots have changed the way small-scale plant businesses operate. Before these standardized pots, nurseries had to make their own small pots, which was time-consuming and expensive. Now, with a reliable supplier, they can buy 1,000 pots for less than the cost of a lunch for two. That\u2019s why so many small businesses can now afford to sell plants at $5 or $6 each, which is perfect for new plant parents who don\u2019t want to spend a lot. It\u2019s a win-win: growers save money, customers save money, and everyone gets a healthy plant.<\/p>\n

<\/p>\n

If you\u2019re a nursery owner, a plant shop manager, or even a hobbyist looking to stock up on pots, you might be surprised at how versatile 40mm pots are. Whether you\u2019re starting vegetable seeds, propagating houseplants, or selling mini succulents, this size works for almost every small plant use case. And if you\u2019re tired of overpaying for pots that are too big or flimsy, a good 40mm pot supplier can help you cut costs while giving your plants the space they need to thrive.<\/p>\n
