Haight Solid State, again.

Automotive LEDs are HORRIBLE for growing. There are 2w diodes brighter than the 6w diodes used in automotive tail lights.

The reason Haight used the Automotive diodes is so they could get away without using fans and such to make such a small panel - the price you pay for higher reliability is lower efficiency as the diodes heat up and the output drastically begins to drop.

Also, the 610nm and white in the panels are wasteful.

You're better off with the HydroGrow lamps. Though I will say that IR most certainly is not necessary. The diodes heating up on their own will produce and emit IR.
