Every January, our candle sales fell off a cliff. The holiday rush that had us pouring past midnight in December would go quiet almost overnight, and by the second week of the new year I would be staring at a full studio wondering how we were going to keep the lights on until spring. That slow season was the thing that finally pushed us to add a second product line, and the one that saved us was reed diffusers.

I am Sabastian, co-founder of Garsnett Beacon Candle Co. We started at our kitchen table during the pandemic and grew into a brand with 160 plus wholesale accounts and a few brick and mortar stores here in Holland, Michigan. Along the way we learned that a candle business built on candles alone has a seasonality problem, and diffusers turned out to be one of the smartest fixes we ever made. If you are learning how to start a candle business and you want something that sells when candles slow down, this one is worth your attention.

Why reed diffusers belong in a candle business

Candles are a fall and winter product for most of us. People burn them when it gets dark early and cold outside. Reed diffusers are the opposite: they are a set it and forget it home scent, and they sell steadily in spring and summer when nobody wants an open flame in a hot house. Adding them smoothed out our revenue and gave our existing customers something new to buy without us launching a whole new brand.

They also solve a real customer problem. Plenty of people cannot burn candles at work, in a dorm, in a rental with strict rules, or around pets and small kids. Every time we told those customers we were sorry, we did not have anything for them, we were watching a sale walk out the door. A diffuser gave us an answer, and it used the same fragrance oils and the same brand we already had.

From a margin standpoint, diffusers are friendly. The vessels are small, the base is inexpensive, and the fragrance load does most of the work. Once you have your candle supply chain figured out, most of a diffuser line just plugs into it. My supply checklist covers the core gear, and diffusers only add a few items on top of what you probably already own.

What actually goes into a reed diffuser

A diffuser is simpler than a candle. You have three parts: a base liquid, fragrance oil, and reeds that wick the scent up into the air. Here is the short version of how we make ours.

1. Start with a real diffuser base. Do not try to use water or plain oil. You want a base made for diffusers so the fragrance travels up the reeds evenly. Your fragrance supplier almost certainly sells one, and it will list the maximum fragrance percentage it can hold.
2. Use a higher fragrance load than a candle. Candles usually run around 6 to 10 percent fragrance. Diffusers typically run 20 to 25 percent, sometimes up to 30 depending on the base. That higher load is why a tiny 4 ounce bottle can scent a whole room.
3. Pick reeds that actually throw. Natural rattan reeds are the classic choice and work fine. Fiber reeds throw noticeably stronger if you want more scent. We use 6 to 8 reeds per bottle and tell customers to flip them once a week.
4. Mix, cap, and let it rest. Combine base and fragrance, cap the bottle, and give it a day for the blend to settle before you insert the reeds and test the throw.

Two things will save you a headache. First, check that your fragrance oil is approved for diffuser use, not just candles, because the safe usage levels are different. Second, watch out for oils high in vanillin. They can discolor a clear base over time, which is fine in an amber bottle but ugly in clear glass. Test every scent before you list it, the same way you burn test your candles.

Pricing and where to sell them

Diffusers price up nicely. A 4 ounce diffuser costs us only a few dollars in materials once you add the bottle, base, fragrance, reeds, and a label, and they retail comfortably in the twenties. That is a healthy margin, but do not guess at it. Run your real numbers through my candle and product calculators so you know your cost of goods and your wholesale and retail prices before you ever list one.

On the selling side, diffusers shine in three places. They are an easy add on at markets and in your online store, where a customer buying a candle will grab a matching diffuser for another room. They are excellent for gift sets, because a candle and a diffuser in the same scent looks like a curated pair and raises your average order value. And they are strong wholesale, because shop owners love a low maintenance product that does not need burn instructions and does not melt on a hot shelf. If wholesale is on your radar, my Wholesale 101 guide walks through pitching stores, and diffusers make an easy addition to a line sheet you are already showing.

Start small and let customers tell you what works

You do not need twelve scents on day one. When we launched diffusers, we picked our four best selling candle fragrances, made a small batch of each, and put them next to those candles in the shop and online. We let the sales tell us which ones deserved a bigger run. Within a couple of seasons, diffusers were a real slice of our revenue and, more importantly, they were carrying us through the months that used to scare me.

If you want to see the kind of products and setups we use day to day, we share a lot of it over on our YouTube channel, and you can see how we present diffusers alongside candles in our own shop at Garsnett Beacon. And if you get stuck or just want to run an idea past other makers, come join the conversation in our free Facebook group. We are all figuring this out together, and a second product line might be the thing that turns your slow season into your steadiest one.
