Replacing hsp 600w globes

Hey all,

just wondering how offen you are all replacing your globes?

Every couple of grows, if you want to maintain the most optimal light levels. After 3-4 cycles of 12/12 for 2+ months at a time, you'll lose about 10-15% or more of the bulbs output. Makes a big difference on yield IME. That's why I won't fork out much more than 20 bucks per bulb these days, and rather pop a new one in, more often than not.

MH depreciate even quicker..

Most do after a few grows i change bulb every run it's personal preference but drop that sound is right after a bit they loose there optimum output levels

I changed them every run aswell, for the price of bulb weighed against the potential loss, just a 1% increase makes them a bargain when buds £10 a gram to buy.
