The PEEKUP mini greenhouse is a clear BPA-free acrylic enclosure that holds heat and humidity around seedlings and humidity-loving houseplants, with 360-degree visibility so you can watch progress without opening it. A magnetic door opens for watering and closes flush, and three movable dividers reconfigure the interior for taller plants or more small pots. Each tiered divider has built-in drainage slots so excess water drains through rather than pooling at the roots, and the base wipes clean. Units stack, so a second doubles capacity on the same footprint. It assembles by hand in under five minutes, no tools. Keep grow lights away from the acrylic. Best fit: seed starting, propagating cuttings, and keeping calatheas and ferns alive in dry indoor air.
Pros
- Traps heat and humidity, which is the difference between a cutting rooting and a cutting rotting
- Magnetic door opens and reseals flush, no zippers to fail like on tent-style greenhouses
- Movable dividers with drainage slots, so it reconfigures for tall or short plants
- Stacks with a second unit, doubling capacity without taking more floor space
Cons
- Acrylic warps above 131F, so a grow light has to sit well away from the panels rather than resting on top
Frequently asked questions
Does it come with a grow light?
No, it is the enclosure only. If you add one, keep it a safe distance from the acrylic and below 131F to avoid warping.
How does watering work without waterlogging the plants?
The tiered dividers have built-in drainage slots so excess water passes through instead of pooling. The base then wipes out.
Can I stack two of them?
Yes, they are designed to stack, which is the intended way to expand capacity on the same footprint.
Is it hard to assemble?
No tools required, and it goes together in about five minutes.
