Founder Diaries · More Reeds, Still Nothing
By Sonal Sahani · ISIPCA Versailles5 min readUpdated August 2026
You did the sensible thing — more reeds ought to mean more fragrance. And in a way it did: the bottle is emptying faster than ever. But the extra reeds are spending your oil, not buying you reach. Projection is set by how a diffuser moves scent, not by how many sticks are soaking in it — and a reed, by design, doesn't push at all.
Quick answer
Why is it finishing faster? More wet reeds = more evaporating surface = more oil used per day. That part is working exactly as expected.
Why no more projection? Reeds evaporate scent into the still air beside the bottle; they can't carry it across the room. Reach is a method limit, not a reed-count one.
The honest fix? If you want walk-in strength, change the method — an active diffuser like SOSA Safar (₹3,999) pushes scent out; reeds never will.
The short version
Short answer: More reeds burn oil faster but don't add reach, because passive reeds can't project — only diffuse close-range.
The pick: Keep the reeds for gentle ambient scent; for real projection add
SOSA Safar (₹3,999), an active waterless nebuliser.
Let me explain what's actually happening inside the bottle, because it's not a fault — it's the diffuser doing exactly what a reed diffuser does. Each reed is a length of porous fibre that wicks oil up from the bottle and holds it as a thin wet film along its whole surface. That film evaporates into the air. The number of reeds decides how much wet surface you have exposed to the room at any moment. Four reeds, four films evaporating. Eight reeds, eight. So when you doubled the reeds, you roughly doubled the surface area giving off scent — and the oil level drops correspondingly faster. A 50ml that lasted eight weeks on four or five reeds might now be gone in a month. That is the reeds working, not failing.
Here is the part that catches everyone out. All that extra evaporation happens into the still air right beside the bottle. A reed has no fan, no pump, no pressure behind it — nothing that actively throws the fragrant air outward. It simply releases scent and then waits for the room's own gentle currents to carry it. Those currents are slow and short-range. So more reeds make the pocket of air around the diffuser smell stronger, and yes, you'll notice it more when you walk past. But the far side of the room barely changes, because nothing is pushing the scent there. You've turned up the strength at the source without extending the range. That's why the honest description of what you bought with those extra reeds is: faster oil use, a touch more close-range intensity, and none of the projection you were really after.
The honest breakdown
What extra reeds actually change
1. They DO use oil faster. More wet reeds = more evaporating surface = the bottle empties sooner. Exactly as designed.
2. They DO lift close-range strength. The air right beside the diffuser smells stronger — noticeable when you pass by.
3. They do NOT add reach. Reeds can't push scent; the far corners stay the same. Projection isn't a reed-count problem.
4. Past about eight, you're just spending. The room saturates near the bottle; extra reeds mostly burn oil for very little gain.
The honest caveat: if you love a strong scent near the diffuser — on a bedside table you sit right beside, say — then more reeds and faster oil use is a fair trade, and there's nothing wrong with it. This only becomes the wrong tool when what you actually want is the whole room to smell of it from the doorway.
Where your oil is really going
Think of it as a budget. Every rupee of oil you own can be spent on either intensity or time — and reeds only ever spend it on intensity in a small pocket of air. They can't convert oil into distance, because distance needs energy the reed doesn't have. An active diffuser spends oil differently: it uses a little pump to atomise the fragrance and physically project it outward, so the same oil reaches further. That's the whole difference between a passive and an active system, and it's why piling on reeds feels like pouring more petrol into a car with no engine — the fuel goes somewhere, just not into forward motion.
When you want reach, not faster oil
SOSA Safar ₹3,999
A waterless, cordless nebuliser that atomises neat fragrance into a fine dry mist and actively pushes it out. Catalogued as a car and travel diffuser — and precisely because it's cordless and high-throw, it doubles beautifully as an on-demand, high-projection scenter for a small room or bedroom. This is the method change that buys reach; reeds only buy close-range strength.

Reed count changes intensity and oil life. It never changes reach — for that you change the method.
The honest core
More reeds spend your oil faster — they don't buy you the projection you wanted.
Reach comes from a diffuser that pushes scent out. A passive reed can only release it and wait, so extra reeds raise close-range strength and empty the bottle sooner, nothing more.
Frequently asked
Why does adding reeds make my diffuser run out faster?
Every reed you add is one more wet surface pulling oil up and evaporating it into the air. More reeds means more total evaporating surface, so the bottle empties faster. That is simple physics, not a fault. Eight reeds will finish a 50ml bottle noticeably sooner than four reeds in the same room, because you are evaporating more oil per day.
If more reeds use more oil, why don't I smell it more strongly across the room?
Because reeds are passive. They evaporate oil into the still air right around the bottle and rely on the room's own air movement to carry it further. Adding reeds raises how much scent sits close to the diffuser, but it cannot push that scent across the room. Reach is a function of the diffusion method, not the reed count, so you end up using more oil for a stronger close-range smell, not more projection.
Am I wasting oil by using more reeds?
If your goal is room-filling projection, then yes, you are paying in oil for something reeds cannot give you. More reeds is worth it up to about eight if you genuinely want the area near the diffuser to smell stronger. Past that you are mostly burning through oil faster for very little extra strength, and none of it becomes real projection across the room.
What should I do if I want real projection instead of faster oil use?
Switch the method rather than the reed count. An active diffuser pushes scent out continuously instead of waiting for the room's air to move it. The SOSA Safar, a waterless cordless nebuliser at ₹3,999, atomises neat fragrance into a fine dry mist and gives genuine walk-in projection in a small room or bedroom. That is the honest fix for projection, whereas more reeds only spends oil faster.
