Nano LEDs

[Garuf]

Visible brightness isn't what matters, it's PAR that does, something can be visibly "bright" but have a very low level of Par which is the important factor for plant growth.

I know but I'm struggling with how I measure the PAR without a meter!?

Just found this:

which on initial look is too complicated for my little brain, but I'm going to read it tonight rather than reading now when I should be working...

You don't, that's why LED's aren't more popular I reckon, they're such an unknown quantity people are reluctant to splash the cash on something that might not be so good.

I'm on the lookout for something cheap and cheerful for my nano.

Don't suppose anyones had any experience with this?

Not cheap and not as attractive as the archaea but is adjustable (height and brightness).

Still tempted by the archaea though. Waiting for AFA to get back to me on plant shipping.
