Id be worried about that stuff getting on or in your medium and fucking up your plants, but thats just meHi, any thoughts on sodium polyacrylate for led heat dissipation. Filled in cheap light weight u channel to lower overall room temperature.( Cheap way )
How would it lower the room temperature......?Filled in cheap light weight u channel to lower overall room temperature.

Here temperature goes to 45c in Summers, In grow room led strips are main source of heat, and proper heatsink would be much expensive, so I'm thinking to use snow power filled in cheap u channel for heat dissipation and that might also help to maintain humidity in grow room.What's your theory ?
Just use the bridgelux strips at nominal amperage (0.7a or 700ma) and you won't need much heat sink. A simple u channel with no powder will be more than enough.Here temperature goes to 45c in Summers, In grow room led strips are main source of heat, and proper heatsink would be much expensive, so I'm thinking to use snow power filled in cheap u channel for heat dissipation and that might also help to maintain humidity in grow room.
That's what I was thinking.This is the stuff inside of ice packs.
I could be wrong. But from my understanding of thermodynamics this will not work unless you put your light in the freezer/fridge everytime before use.
basically this material has a very high heat capacity so it can absorb a lot of heat, however since it's absorbing the heat it will keep the LEDs hot especially once saturated for temperature. Maybe one benefit would be it could improve the heat transfer from the led strips to the rest of the aluminum heat sink, but aluminum already distributes heat pretty well.
edit:also you might have to keep adding distilled water to the light since some should evaporate if the heat sink is not sealed.
You could try something I was toying with , air cooled LEDs.Here temperature goes to 45c in Summers, In grow room led strips are main source of heat, and proper heatsink would be much expensive, so I'm thinking to use snow power filled in cheap u channel for heat dissipation and that might also help to maintain humidity in grow room.
Do you recommend blowing it underneath light upwards or above ?How would it lower the room temperature......?
Just put a fan blowing over the heatsink
In my case I need all the heat I can get so I blow the heat downwards.Do you recommend blowing it underneath light upwards or above ?
I think the primary effect here would be evaporative heat loss. The polymer would simply dry up as the water escapes. This material is essentially inert. It retains water (hydrophilic) and expands as it absorbs water. I wouldn't waste your money on the 'artificial snow'.... any cheap polyacrylate polymer will do the trick... see "diaper absorbent"This is the stuff inside of ice packs.

I not only imagined it, I built it. I only run in the winter now so the water isn't used, it just runs passively. I thought about doing the same thing with larger square tubing and circulating air through it.Also, it's never been that popular but there's been some brilliant water cooled systems using cobs back in the day.
Imagine fully welded aluminium or copper box tube with strips attached, you could even feed your hot water system with it to save energy
