The results I see here are IMO BLUE results... Not actual ultra violet results.. Hence thicker leaves and such..

Old Mac... You should try 420 Actinic T5 bulbs... You'll get the same results as those UVb bulbs and be much safer IMO...

Thicker leaves and more trics are the results I'm getting from the T5 420 Actinic fish tank bulb..

One thing I didn't see here is that the potency was better from chamber 1... Sure more overall weight and more trics in 3 of the 5 strains but was chamber 1 the most potent of the three chambers?

If I had to guess... I would say not much better then chamber 2.. Of course chamber 3 will be less potent by default because it couldn't ripen all the way (trics going from cloudy to amber)..

Old Mac if it's extra potency your looking for.... I'm afraid you'll have to experiment with Far Red...


Great experiment OM.. :thumbsup:
