MADE FOR FIREFLY FROST GUARD USE Finding the right refill candles matters when you want a simple replacement for your frost guard setup. This Bio Green candle refill set is designed for the FireFly frost guard, helping you replace used candles with a compatible option. Each pack contains 6 biomass candles, giving you a practical refill supply for ongoing seasonal use. It is a straightforward choice for gardeners looking for dedicated FireFly candles rather than general household candles LONG BURN TIME FOR PRACTICAL USE Short burn times can be frustrating when you need dependable coverage. These biomass candles are listed with a minimum burn time of 42 hours per candle, giving you a longer-lasting option for your frost guard setup. That extended burn time makes them more practical for greenhouse and cold-weather use. For buyers comparing refill options, the long-burn format is a clear everyday advantage. REWAX BIOMASS FORMULATION The product is described by Bio Green as being made from REWAX biomass, with messaging around resource-saving production and upcycling of residual materials from the food industry. That gives shoppers a clearer product story than a standard generic candle refill. I would keep this benefit focused on the material and intended use rather than stronger environmental claims that may be harder to support on Amazon. It is a cleaner way to position the product while staying conversion-friendly. SET OF 6 REFILL CANDLES Running out of replacement candles too quickly can interrupt your setup. This pack includes 6 candles, making it easier to stock up for repeat use in your FireFly frost guard. A multi-pack format is also more convenient than buying single replacements one at a time. For seasonal greenhouse users, it offers a more practical refill option. COMPACT FORMAT FOR SPECIALISED USE Specialized frost guard candles need to fit the intended system properly. Bio Green lists each candle at approximately 10 cm high by 6.3 cm diameter, with about 200 g weight per candle and around 40W heat output per candle. Those details help position the product clearly as a purpose-built frost guard candle refill rather than a decorative candle. That makes the listing more relevant for shoppers searching for greenhouse-use candles.
