ok,
so ive used the same hps bulb that came with my ballast for the last 3 crops,
allthough i cant notice any drop in performance i think it may be time for a new bulb,

current bulb is a 400w sylvania grolux

my question is....

which 400w hps bulb performs the best during flower?

i dont use the hps to veg with at all so dual spectrum isnt really needed i dont think, unless it helps during flower,


thanks,

ok,
ive looked on ebay for the suggested lamps but cant seem to find any 430w bulbs in the u.k,

i have found this though,
SOLARBURST 400 watt HIGH-PRESSURE-SODIUM Super NAV-T


does anyone have any experience with this bulb?
is it any better than a sylvania grolux?

im kinda restricted to buying from ebay as i have the money in my paypal acc with no bank registered so no way of cashing out lol,
also would prether to order from u.k only ebay sellers as i dont fancy the bulbs chance of making it al the way from the u.s.a lol,

hey right lamps are not tricky to decide on but if your looking for a 400w hps then go to http://www.greenshorticulture.co.uk
this site is amazing and has everything anyone needs, i bought my 250w euro grow light with reflector and ballast for £90 but there are lots of different ones :) please let me know how you get on :)
