What is the minimum lead time for scenting a launch? Realistically about a week, and the compromise is the testing rather than the equipment. You can have a SOSA Vaayu (₹11,999) running in a space within days, but choosing a fragrance for a two-year project signature in an afternoon is the part you will regret. If the launch is close, shortlist two profiles instead of five and test both in the actual space for three days.
How long before doors open should the scent machine start? Forty-five minutes. That allows the fragrance to diffuse through the volume and settle to a level that reads as the smell of the building rather than something just switched on. Set it on the SOSA Vaayu (₹11,999) app during setup, on a 4h timer, so nobody has to remember it on launch morning.

Facts verified 24 August 2026 against the live SOSA product pages: the SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³, described by the manufacturer as approximately 2,000-3,000 sq ft, with a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, Bluetooth app and button control, 1h/4h/8h/24h timers, adjustable intensity, operation under 38dB, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, and also runs standalone wall-mounted or lay-flat. Scent enhances the ambience and perceived quality of a space; it works alongside proper ventilation and cleaning and is not a substitute for either, and SOSA makes no claim that fragrance alone influences a purchase decision. The hotel-inspired scents are SOSA's own original interpretations; SOSA is an independent brand and is not affiliated with, or endorsed by, any hotel named for reference. Coverage, fragrance usage and running cost depend on the space, settings and hours of use, and are confirmed on a consultation. Prices and availability are subject to change - see the live product pages.
Launch run-ups are measured in days, not months, and scenting is usually raised in the last week when everything else is already contested. It does not need to be. Here is the countdown that actually works, what each step is for, and which one you can compress when the date has moved forward again.
Quick answers — read this first
How early should a developer plan scenting before a project launch? About three weeks. Decide the machine count at 21 days out and raise the order, have the machines on site by 14 days so a shortlist can run in the actual space, lock the fragrance at around 7 days, then fill and set the app timers 48 hours before so the space runs in. On the day itself, a SOSA Vaayu (₹11,999) should start 45 minutes before doors. Ten days is workable if the fragrance decision is made quickly.What is the minimum lead time for scenting a launch?

The short answer
Short answer: about three weeks - decide the count and order at 21 days, get the machines on site by 14 days to test a shortlist in the real space, lock the fragrance at 7 days, fill and program the timers 48 hours out so the space runs in, then start the SOSA Vaayu (₹11,999) 45 minutes before doors on the day; ten days is workable, the evening before is not.
The pick: order the SOSA Vaayu (₹11,999) first, since it covers most launch volumes at 1000m³, and order the SOSA Angaan (₹25,999) earlier still if the launch hall is 8,000-10,000 sq ft, because that decision changes the whole plan.

Scenting is one of the few launch decisions that can be finished early and then left alone. The only irreversible step is choosing the fragrance, and that needs a few days of testing in the actual space rather than a paper strip in a meeting room.

Straight answer
How many days before launch should we start planning the scenting?
Three weeks is comfortable and ten days is workable. Here is the countdown. At 21 days, decide how many machines you need - one SOSA Vaayu (₹11,999) per separately moving body of air up to 1000m³, roughly 2,000-3,000 sq ft, or one SOSA Angaan (₹25,999) where a single hall runs to 8,000-10,000 sq ft - and raise the purchase order. That decision is the long pole, because it is the only one with a delivery time attached. At 14 days, have the machines on site and start running a shortlist of two or three fragrances in the actual space, a few days each. This is the step teams skip and then regret, because an air-conditioned interior flattens sweetness and lifts anything heavy, and a paper strip in a meeting room predicts none of that. At 7 days, lock the fragrance and order it for every machine on the site, including the sales gallery and the sample flat, because from launch night onwards it is the project's signature. At 48 hours, fill the tanks, set the app timers - a 4h schedule for the launch space, an 8h schedule for the gallery - and let the space run in, so that on the day it smells settled rather than newly perfumed. On launch morning, the only remaining task is that the machine starts 45 minutes before doors, and if you set the timer at 48 hours, that has already happened without you. Two things that break the timeline. Fresh paint, adhesive and new flooring need curing and ventilation, and no amount of lead time on the fragrance fixes a space that was handed over four days ago - ventilate first, scent after. And if the launch date moves forward, compress the testing window rather than the run-in: two profiles for three days each is a real test, and 48 hours of settling is what makes the room read as finished. A free scenting plan will work the countdown backwards from your date, and a portion of every order supports girl-child education through Nanhi Kali.
21 days to order, 14 to test, 7 to lock the fragrance, 48 hours to run it in, 45 minutes before doors to start. Compress the testing, never the run-in.
The order you raise at 21 days is usually a SOSA Vaayu per space - rated to 1000m³ (about 2,000-3,000 sq ft), with a 400ml tank lasting up to 75 days, so the fill you use for the two-week test is very often still running on launch night and into the gallery afterwards.

There are only two things on the purchase order, and the count is settled before the fragrance is. Order the machines first, because they are the part with a lead time.
Order at 21 days, one per space
SOSA Vaayu
Rated to 1000m³, about 2,000-3,000 sq ft, so most launches order two or three. 400ml tank lasting up to 75 days, Bluetooth app with 1h/4h/8h/24h timers, under 38dB, key-lock. Having it on site by day 14 is what makes a real fragrance test possible.
From ₹11,999
The gallery unit - order it in the same purchase order
SOSA Vaayu (second unit)
The gallery machine should arrive with the launch machine, not after it, so both can be tested on the same shortlist and set to their different schedules during the same 48-hour run-in.
From ₹11,999
A launch hall of 8,000-10,000 sq ft - decide this earliest
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³, 800ml reservoir, metal body, programmable schedules, under 42dB. If your launch hall is this size, settle it at the start of the countdown, because it changes the plan for every other space.
From ₹25,999
The countdown, day by day
The countdown has three phases, and only one of them is genuinely compressible when the launch date moves.
1
21 to 14 days - order and arrive
Settle the count first, because it is the only part with a lead time
Work out the air volume of each enclosed space, divide by 1000m³, and raise the order for that many Vaayu units, or for one Angaan where a single hall is 8,000-10,000 sq ft. Do this before you have any opinion about fragrance, because the count does not depend on the scent and waiting to decide one delays the other. Getting the machines on site by day 14 is what makes the next phase possible at all. Order the gallery and sample flat units at the same time rather than later.
Tip: raise the machine order before the fragrance conversation starts, not after it.
One Vaayu per 1000m³ of connected air, about 2,000-3,000 sq ft, is the whole count for most launches.

2
14 to 7 days - test in the real space
Two or three profiles, a few days each, judged by walking in from outside
This is the phase that gets cut and should not be. An air-conditioned interior flattens sweetness and lifts anything heavy, so a fragrance shortlisted in a meeting room can behave completely differently in the gallery. Run each candidate for three or four days and judge it by walking in from outside, because you stop registering a scent within minutes of standing in it. Lock the winner by day 7 and order it for every machine on site, since this becomes the project's signature for the next two years.
If the hall runs on an Angaan, test the same profile there too - a large volume can read differently from a small one.
See SOSA Angaan →
3
48 hours to launch morning
Fill, program, run in, and then do nothing on the day
Two days out, fill the tanks and set the schedules in the app: a 4h timer for the launch space, an 8h timer for the gallery, both at the intensity you settled during testing. Then let the space simply run for 48 hours. A room that has been quietly fragranced for two days smells settled; a room fragranced for twenty minutes smells sprayed, and the difference is obvious to everyone even if nobody can name it. On the morning itself the timer has already started the machine 45 minutes before doors and nobody has to think about it.
Tip: if the date moves forward, cut the testing window, never the 48-hour run-in.
The Vaayu holds 1h, 4h, 8h and 24h schedules with adjustable intensity, so the run-in and launch day are the same setting, already saved.

The SOSA principle
Scenting is the rare launch line item that can be finished a week early and then genuinely left alone.
The equipment takes days. The fragrance decision takes a week of living with it, and that is the part worth protecting in the schedule.

The one decision in this countdown you cannot take back is the fragrance, so read the signature fragrance guide for a luxury property launch before the shortlist goes out - it explains which profiles survive a warm crowded hall and still read well in year two. If you are starting the countdown from nothing, the complete fragrance setup for a project launch is the kit list that sits alongside this timeline. And for the space that inherits all of it afterwards, see the pillar guide on planning scenting for a luxury real estate sales gallery.

Timers programmed at 48 hours mean launch morning has one less decision in it
The SOSA launch countdown specification
Two machines on the purchase order, and the count is what you settle first. The Vaayu covers a normal-height launch space, the gallery and the sample flat at 1000m³ each; the Angaan takes a hall of 8,000-10,000 sq ft and should be decided at the very start of the countdown because it changes everything downstream. Both are made in India, and a portion of every order supports girl-child education through Nanhi Kali.

A quick word on sequencing: order the machines before the fragrance conversation begins, because the count does not depend on the scent and waiting delays both. One honest note - fragrance works alongside curing, ventilation and cleaning during fit-out, cannot cover fresh paint, adhesive or damp, and SOSA makes no claim that scent influences a purchase decision.

A note from Sonal
Nearly every launch enquiry we get arrives with about eleven days left, usually from a marketing head who has just walked through a gallery that smells of new carpet. That is survivable. What is not survivable is the call that comes the afternoon before, asking whether we can courier something overnight, because the part that takes time is not the machine. It is knowing whether the fragrance you have chosen will still be right at eight in the evening with four hundred people in the room.
So my countdown is this. Three weeks out, work out the count and order - one Vaayu per 1000m³ of connected air, or an Angaan if a single hall is 8,000 to 10,000 sq ft. Two weeks out, run a shortlist in the actual rooms, not on paper strips. One week out, lock it and order for every machine. Two days out, fill, set the timers and let the space run in. Then, on the morning itself, do nothing at all, which on launch day is a gift.
The honest part: no lead time fixes a space that still smells of construction. Fresh paint, adhesive and new flooring need ventilation and curing, and fragrance layered over them gives you both smells at once. If the gallery was handed over four days before launch, open it up and air it rather than scenting harder. And we make no claim that fragrance influences a purchase decision. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How many days before a launch should scenting be planned?
About 21 days is comfortable. Order the machines at 21 days, have them on site by 14 so a fragrance shortlist can run in the real space, lock the fragrance at 7, and fill and program the timers 48 hours out so the space runs in. Ten days is workable if the fragrance decision is made quickly.
What is the absolute minimum lead time?
Around a week, and what suffers is the testing rather than the equipment. A SOSA Vaayu at Rs 11,999 can be running in a space within days, but choosing a two-year project signature in a single afternoon is the part you will regret. With a short run-up, shortlist two profiles instead of five and give each three days in the actual room.
How long before the doors open should the machine start on launch day?
Forty-five minutes. That lets the fragrance diffuse and settle so it reads as the smell of the building rather than something switched on as guests arrive. Set it on the app during the 48 hour run-in, on a 4 hour timer, and launch morning takes care of itself.
Will one tank of fragrance last through the launch?
Comfortably. A 400ml SOSA Vaayu tank lasts up to about 75 days depending on intensity and run hours, so the fill you put in for the two-week test is usually still running on launch night and well into the sales gallery period afterwards.
Can we scent a gallery that was painted a few days before the launch?
Not effectively. Paint, adhesive and new flooring need curing and ventilation, and fragrance layered on top gives you both smells at once, which is worse than either. Air the space out properly first and scent the clean space. Fragrance works alongside ventilation and cleaning, never instead of them.
Three weeks is comfortable. Ten days is workable. Tonight is not.
