Re: Leggy plants

[Anthony Law <sulfur at yahoo_com>]

(Rachel was wondering why all her plants are leggy. 
Adam & Tom asked about macro & traces dosage, etc)

Ok I've followed this entire thread with interest but
am surprised nobody commented on this:

I thought regular tubes are good for 6 mths & PC for
12 mths.  So your 4x55W PC will have very little
intensity left after 18 mths!

Sounds like you're dosing a ton of nutrients & CO2 but
giving them crappy lighting.  No?

Cheers,

Anthony.
