Running Hps Lights on floor

thegrower12 · May 11, 2023

Has anyone run hps lights on the floor facing up ? Have LED’s up above and have 4 hps lights that i swapped out for the LEDs just sitting there and thought this as an idea ?
Anyone done this ?
Any cons attempting this?

While it's not a common practice, it is possible to run HPS lights on the floor facing up. However, there are some potential cons to consider, such as heat issues, light distribution, and potential damage to the floor. It's worth experimenting with if you have the extra lights, but keep a close eye on the plants and adjust as necessary

Its winter so heat issues should be fine only running at 250-400w x4
Will put on couple bricks either side to stabalise so no damage to floor

TG,

I had suggested that in in earlier post. But maybe consider directing the lights lower on the plants and more or less at the sides of plants rather than floor facing up. Not sure if a lower leaf surface is all that efficient in collecting light.

I agree side lighting, not floor lighting. I've seen folks use led above and HPS hanging with no reflector down between the plants for side lighting. rotate the plants 2-3 times a day so all sides get the light.
