Not for me. I don't think my eye hortilux hps is going to be so much better than a plantmax at the same wattage and kelvin.There seems to be a lot of hype about X brand of HPS bulbs being the best...Is there a noticeable difference between a premium like a hortilux and other brands? - I'm currently using a 600w GE PSL bulb.
For that my friend I'll have to refer you to another source..Go herethanks - that makes me feel better - i didnt think one bulb could be so dramatically better than the next...you seem to know the science with this stuff - I use the whole botanicare line but don't get that pungent aroma I love - is there an additive I can use to stink up and firm up the buds>?
4000K MH was what I was using and is the common MH standard bulb. Then I got a 7200K MH for veg and it really changed things in my grow.As long as your careful not to be to cheap in buying bulbs, brands don't matter so much as long as their in the right spectrum. Cheaper bulbs always loose efficiency sooner then better built bulbs, in my experiences anyway.
@giantsfan24 you went from 4000K to 7200K? You probably haven't seen much of a difference because both are the wrong kelvin...?
