Firecracker Plant

Bright light to full sun (6 or more hours of sun hitting the leaves per day. South-facing window, no obstructions. Under grow lights, keep them 4-8 inches away for 12-14 hours) from a south- or west-facing window. Moving it outdoors for summer gives it the intensity it needs for prolific blooming. low light (more than 8 feet from a window, or a north-facing room. A grow light 10-12 inches away works great if your windows are not cutting it) produces leggy growth and far fewer flowers.

Needs at least 40-45% relative humidity. Prefers higher. Use a humidifier, pebble tray, or occasional misting (note: misting does not actually raise humidity meaningfully. A pebble tray or humidifier is more effective) during dry spells. Indoor air in winter can drop below its comfort zone without you noticing.

Rich, well-draining potting mix. Standard all-purpose mix with added perlite works well. Avoid heavy, compacting mixes.

Leggy growth in low light is the most common issue. Scale and spider mites occasionally appear. Cut vines back by half in spring to encourage bushy, compact growth.
