While implementing Restrictions on Community Activities (PPKM), why would you try something new, like planting seeds? You can start with terrarium plants as aside it's easy to care for, they also can beautify your room. Here are the recommended terrarium plants and the best closed of them. 

Mosses (Bryophytes)

Because of these unique characteristics, mosses absorb water primarily through their leaves, which usually consist of just a single layer of cells. This means that these tiny plants need to be constantly in contact with moisture.

Mosses are often used for ground cover in closed terrariums because they thrive in moist environments, they don’t take up much vertical space due to their low profile and lack of root systems, and they are very slow growers. Also, since mosses prefer full shade, they don’t mind being blocked by larger plant foliage in the tight confines.

Sempervivums 

Sempervivums are versatile plants. They can be kept in pots, bowls, troughs, or open ground, such as a rock garden. They're outdoor plants, part of the group of alpines or rock plants, which like a sunny position - ideally getting as much sun as possible, but at least for part of the day. They survive sub-zero temperatures in winter, and natural rainfall is enough in spring/summer, so supplementary watering is not usually required once they're established.

Small Ferns

Plant ferns in part to full shade and rich, well-drained soil. In all climates, they need protection from the afternoon sun to prevent drying and leaf scorch. Ferns can reach 12 inches to 6 feet tall, depending on the type and growing conditions. Most prefer rich, humus-filled soil, so make sure to mix compost into planting holes and cover them annually with 2 inches of organic mulch. Like other perennial plants, you can divide ferns in spring or fall. Keep the new divisions well-watered until plants are established.

Mini Moth Orchids

Those miniature phalaenopsis orchids (Phalaenopsis) with tiny flowers sold everywhere these days are not cute babies in early bloom. Any orchid in flower is fully mature, or it wouldn’t be flowering. They genuinely are genetic miniatures, the chihuahuas of the orchid world, and won’t get bigger over time bigger much more extensive over time.

If you like tiny orchids with tiny flowers, go ahead and buy one. If you prefer more enormous orchids with big flowers, buy one of those.

Miniature English Ivy

Ivy can make a wonderful, bright light houseplant. It can grow long and lush and bring a bit of the outdoors inside. Growing ivy indoors is easy as long as you know what makes an ivy plant happy.

Growing ivy indoors isn’t difficult as long as you provide what the plant needs. The most important part of indoor ivy plant care is light. All true ivies need bright light. Variegated cultivars can take medium light, but be aware that their variegation will become less pronounced in less light. Without enough light, inside ivy plants will become leggy and sickly looking. They will also be more prone to pests.
