Phalaenopsis orchids require warm temperatures and low lighting.
Orchids are bright, elegant plants in home-growing situations, with blooms that last for weeks and long lifespans. The plants grow well in groups for colorful effect but require specific conditions to maintain health. Set up an orchid terrarium or enclosed planter to maintain humidity and warmth around these sensitive plants. Use specific planting foundations and select similar orchids for best growing success.

Instructions
1. Choose an appropriate terrarium for orchids. Terrariums with lids or windows allow for better air movement, while larger and taller terrariums offer more room for ultimate growth and planting.
2. Line the bottom of the terrarium with 2-to-3 inches of gravel for drainage. Orchids cannot survive in standing water and thrive in free-draining situations. Lay a half-inch of charcoal over the gravel to keep the base clean and the orchid roots from growing down into the water and gravel.
3. Mix peat moss and gravel in equal parts as a strong, supportive foundation. Lay 4 inches of the mixture over the charcoal. This foundation gives orchids free drainage and room for root growth, with good air movement around the roots. Orchids don't thrive in tight or thick traditional soil because their roots need to breathe.
4. Plant a range of orchid cultivars from the same family with similar growing needs for success. Choose from the Phalaenopsis, Dendrobium, Cymbidium or Oncidium families for a wide cultivar selection. Plant the orchids in holes deep and wide enough for their root balls, with all foliage reaching above soil level.
5. Stick bamboo stakes into the planting foundation next to each orchid. If the orchids have flower stalks, clip them to these stakes. The stakes secure the foundation and support the orchid stalks as they grow.
6. Put the terrarium in a place with all-day artificial or indirect light. Never put terrariums in full sunlight because it cooks the plants inside. Orchids do best with artificial lighting or bright, indirect sunlight.
