Should i switch to HPS?

As the fall already begun, my grow room temp is about 20-21 °C (68°F). As some suggest, the LED panels won't be suitable to provide the best potential under such conditions, a higher temp being preferred. In this scenario, what would you suggest? Should i switch to a 400W HPS or continue the flowering phase under the LED panel?

If it's gonna cost you the same or more to run the led with extra heat to compensate for the colder temps then you be as well as running just the hps I think during the colder parts of the year if not then crack on with the led

Abso fricking lutely…. I prefer HPS period but it’s the for sure winner in winter cultivation if you’re in a colder climate

I keep a HPS around for winter grows. The direct IR helps alot even in cold rooms.

HPS no doubt, if you work in a big space, split your lights (2x400 or 2x250 etc)

Use both, and grow more!?

You can fairly easily build your own custom solution to this if you want an in between step aswell for spring and autumn: diy ledstrips around a centre hps, which you can replace by another strip array for the summer. Best of two worlds.

Id use a 600w MassMedicalStrains Halide. They do make a 400w, if you want to go that route.

Its the closest thing to the Hortlulx Blue, there is. Which was $150-$200.
The MMS 1000w Halide Bulb, is only $70 usd.
They dont make Hortilux Blue anymore, and this New Halide, is 20% more powerful, than the Blue.

While its true, an HPS, will produce more weed. The Halide, is the closest thing these is to the spectrum, of the sun.
The bulb has a 280nm-2400nm spectrum.
The Halide, will also keep the stretch down a bit, as the more Red, in the HPS, will for sure promote larger plants.
But while LED-HPS, Halide, can all grow good weed. I believe the Halide, brings out more expressions in the plants.

While anyone can say anything.
MMS claims they did do chemical testing Halide vs HPS, and the Halide, had a more varied chemical profile.

IMHO a 600w is best, for a 3ft x 3ft area. 400w- 2.5ft x 2.5ft. 1000w 4ft x 4ft.

MH and HPS science is getting old, HPS wins everytime solely due to light output.

All results and conclusions about quality in the HIDs realm (yes even CMH) are pointing at sheer output as king, not spectrum.
The difference between MH bud and HPS bud ? Marginal at best if any.
No reason to lose 30% light at the same watt.

Remember, genetics are 99% responsible for what you'll get, not the lights.. well except LEDs which bombard plants with EMF aswell.

If you like the performance of LEDs, always split your HIDs, spread is king.
