SPD = Spectral Power Distribution, ie spectrum...

The one with the spectrum graphics above is this:

Very $$$$, specs at link...my only complaint is that it doesn’t cover UVC->UVA wavelengths.

For intensity (ppfd), i generally use this:

A less expensive tool for intensity is a lux meter, depending on brand/model...the mfg co should be able to provide the lux to ppfd conversion factor for lights to convert lux to ppfd. Here is a common one:

Thank you Ordered the lux meter. Looking for the conversion factor for Bridgelux EB Gen 2's... any hints?

I’m a true believer in defol.

Under optimal conditions, up to the end of stretch, a healthy plant will produce whatever leaves it needs.

The two primary reasons i defol are: to prevent the plant from using its energy to support an undesired part of the plant, and to remove a part of the plant that is blocking light or airflow.

When a leaf is removed, energy is redirected to what is left on the plant, with priority to the growing tip, supported by the same roots mass as before defol...

Further discussion about defol can be found at the growweedeasy link above.

I always tell novice defoliators that if you don't feel defol remorse after defol’ing, then you haven’t removed enuff leaves.

This morning i took a shipload of leaves, but didn’t feel bad...

So, i went at it again...

Before defol:

6x96


8x288



After defol:

6x96


8x288


Lol...still not feelin it!
