Two-Layer Planter with Clear Reservoir, 4.1 in

$34.99

Color

A small ribbed planter in two parts, with a clear lower section so you can see the water sitting under the pot.

Most small pots hide the one thing you need to know. You water, some runs through, and whether the root ball is wet or dry is a guess until you dig a finger in.

This one is built in two pieces: an inner cup that holds the plant and potting mix, sitting inside a clear outer section that catches what drains through. You can see at a glance whether there is water down there.

It also means no saucer to knock off a shelf and no ring left on the furniture, which is most of why these end up on desks and windowsills.

  1. Lift the inner cup out of the clear outer section.
  2. Pot your plant into the inner cup as you normally would.
  3. Set it back into the outer section and water from the top.
  4. Check the clear section afterwards. If a lot of water has collected, lift the inner cup and tip it out rather than leaving the mix standing in it.
  5. Keep judging when to water by the soil itself. The window shows you what has drained through, not how wet the root ball is.
  • Size: 4.13 in across, 4.72 in tall (10.5 x 12 cm)
  • Construction: inner planting cup plus a clear outer section
  • Material: plastic, listed by the supplier as PS
  • Finish: vertical ribbed texture, translucent
  • Colors: blue, green or gray

Treat it as a planter with a see-through reservoir, and keep watering it yourself.

One size, three colours. Blue, green and gray are the same pot with the same ribbed finish, all translucent enough to show the water level.

At 4.13 inches across it suits a small houseplant: a pothos cutting, a young peace lily, a herb from the supermarket, a lucky bamboo. Anything with a root ball wider than about 4 inches will want repotting first.

  • Potting mix left standing in water is the fastest route to root rot. If the lower section fills, empty it.
  • This is a small pot. Small pots dry out quickly, especially in a warm room.
  • Translucent plastic lets light reach the mix, which can encourage algae on the inside of the wall. It is cosmetic, and rinsing sorts it.
  • Thin plastic in strong sun clouds and goes brittle over time.
  • Colours vary a little between batches and screens.

Do I still need to water it?

Yes. The clear outer section shows you what has drained through, but water it yourself as you would any pot.

How big a plant fits?

It is 4.13 in (10.5 cm) across and 4.72 in (12 cm) tall, so think small houseplant, herb or cutting rather than anything established.

Should I leave water in the bottom?

A shallow amount after watering is normal. A pot sitting in standing water for days is not, and that is what causes most root problems in containers like this.

Can I grow in water alone?

People do use pots like this for cuttings rooting in water, and the clear section makes that easy to watch. Nothing about the pot is designed for it specifically, though.

Is it OK outside?

It is a light indoor pot. It will blow over on a balcony, and rain will fill the lower section without asking.

Why you'll love it

You can see the water. The clear lower section shows what has drained through, so nothing is hidden under an opaque pot.

No separate saucer. The catch tray is part of the pot, so there is nothing to slide off a shelf and no ring on the desk.

Lifts apart in a second. The inner cup comes straight out, which makes potting up and emptying the base easy.

Reading the water line

A clear reservoir is genuinely useful, as long as you read it for what it is. What you can see is the water that has already passed through the potting mix, not how wet the root ball still is. Those are different things, and only one of them tells you whether to water.

So keep using your finger. Push it an inch into the mix; if it comes out dry, water, and if it comes out damp, wait. Overwatering kills far more houseplants than underwatering does, and a small pot in a warm room can look bone dry on top while still being wet underneath.

The useful habit with a pot like this is to check the base an hour after you water. A little water sitting there is fine and will be taken back up or evaporate. A pot standing in water all week is the beginning of root rot, so lift the inner cup and tip it out.

Do that a few times and you will learn how much your plant actually takes, which is the whole point of being able to see it.

A quick guide for your growing space

Heat

Pots dry out far faster than garden beds in a hot spell, and a small one can empty in a day. Check the top inch of soil before you top anything up rather than watering on autopilot.

Humidity

Damp air slows evaporation, so soil stays wet longer than you would expect. In a humid stretch, water less often rather than on a fixed schedule, and make sure every pot can drain freely.

Frost

Water left in bottles, tubing or a reservoir can freeze and split it. Drain and store watering gear before the first hard freeze, and water in the morning so roots are not sitting wet overnight.

Small spaces

Balconies and patios catch wind and reflected heat, which dries containers faster than an open garden. Grouping pots together helps them hold moisture a little longer.
