PGLs

sunahura · Sep 5, 2009

I found a site that explained PGLs vs lumens, it seemed that florescents are equal if not superior to HPS.

But HPS are known for tight thick buds, are thier any pros who can vouch for 2700k 68 watts or better CFLs.

I grew under fluro's for many years, and now use 2 600w HPs. While I still believe fluros are adequate, HPS are much faster during the crucial first few weeks of bud formation.

Is your harvest yield any different per watt?

PGL....I seriously thought the guy was pulling that out of his ass till I started to google it. Cool read.

I think this knowledge can go a long way into more productive light setups.

Yeah, the tighter buds hps allow for weigh more than the often smaller and loose/fluffy fluro-buds. Haven't actually compared watt/yield ratio, but get about 2 Z's off small plants (foot n' halfers) w/hps.
Fluro buds very nice tho. Look, smell great . . . nice bag appeal for those preferring loose?

Sounds good to me, I use CFL's, MH, and HPS, just to round them off, THis is my first time with this and it's working well so far.

The price is right! Have a blast.

Way too much math and calculations involved. I just stick with PAR.

What is PAR

photo synthetically active radiation

good little thread, i completed my 1st grow with all cfl's - yield was 35g under 78w of cfl - about 0.45g/watt though many don't like the gram/watt measure

Not bad, 4 more 78's and that would be 10 z's, I like. :bigjoint:
