Suitable for various conditions: Grows in both full sun and partial shade, indoors or outdoors
Summarized by Shop
The fastest nutrient sponge you can buy. Lemna minor — Duckweed — is barely 2mm across but multiplies faster than almost any aquatic plant, forming a dense surface mat that shades algae out and strips nitrate and phosphate from the water as it goes. Ponds and heavily stocked tanks clear noticeably with it.

No directions
It would have been nice to get some directions in how to introduce the duckweed to the pond. As it is very few of them lasted more than a week. They seemed to get too much sun exposure. I wasn't aware that they would need to be hardened before adding them. :*(

All the duckweed
Ordered some duckweed, and they arrived not only earlier than expected. They also arrived so green and without any damage to the plant. 10/10 would recommend 👍
