If you love succulents but have no way to grow them outdoors, good news: Numerous varieties thrive indoors. Below are cultivation tips and a photo gallery of 40+ indoor succulents that are readily available.
Place your succulents near a window
Most succulents are from arid regions with lots of sunlight, so they're not going to be happy in low light. A succulent starved for sun will etiolate: flatten and elongate to expose more of its surface area. It also will lean in the direction of greatest sun. Maximum sun exposure is on the south and west sides of your house. The farther north you live in North America, east will provide bright light, but not enough for crassulas, echeverias and aloes to maintain their red hues.
Give good air circulation
Succulents enjoy fresh air and breezes that keep pests from settling in. Without good air circulation, succulents in cramped conditions are at risk of mealy bugs, spider mites and other pests. At the first sign of infestation, spray with 70% Isopropyl alcohol. Isolate infested plants so pests don't spread, and clean the surrounding area.
They Like it Dry
Aim to keep soil about as moist as a wrung-out sponge. Succulents do best in low humidity. A moist environment can cause problems with fungus and rot. But don't set succulents near heaters or furnace vents. This can cause the soil to dry out completely, causing roots to desiccate and growth to cease.
Install Grow Lights
Situate indoor succulents beneath lights that stay on six hours daily. Fluorescent is fine and economical. Experts in growing succulents in gray-sky climates recommend T-5 grow lights. If your plants stretch toward light (or flatten their rosettes to expose more of their surface area), add more lights or move the plants closer to the ones you have.

No room? Go vertical. Create a "light island."
There are shelving units designed for indoor plants. Each shelf has a waterproof tray, and each unit is lit by two T5 bulbs. The lights, on timers, stay on from 7 am to 7 pm daily.
Shown here is arguably the ultimate indoor plant-shelf unit. Made of lightweight, powder-coated aluminum, it has adjustable lights with energy-efficient, full-spectrum bulbs; plastic drip trays; and wheels for easy positioning. Three shelves provide 18 square feet of growing space.

Watch the temperature
If it falls below freezing (32 degrees F) many succulents may show long-term damage (or die). This indoor thermometer is digital and also has a humidity gauge. But what I love about it is that it keeps a record of daily high and low temps for 24 hours!
