eye hortilux or MH?

Hi, im currently vegging a few mr. nice critical mass and a couple of ghs big bang. I have them under a 400w hps and tbh they arnt growing too well at the moment, the last big bangs i grew did much better under a 125w blue cfl so im thinking i need more blue spectrum in there

Which bulb should i use? a mh or something like the eye hortilux? Iv heard people on this site say you can use any mh bulb with a digital hps ballast, is that true? if that is the case id prob get a mh bulb and save my son t plus for 12/12

i use the hortilux with good results.

thanks for the reply, yeah iv heard good things about the hortilux

anyone know if i can run any 400w mh bulb in my 400w digital hps ballast?

Hortilux Metal Ace 400 watt conversion metal-halide bulbs run on HPS ballasts.$89.00 Cdn at Homegrown Hydroponics.

aah i cant find any eye hortilux in the uk except on ebay but there being posted from the usa

i have noticed on the add for my ballast it says it is hps and mh compatible

Basement Lighting Hydroponics and Grow Lights UK

so might try a mh

Sorry m8, didn't realize you were in UK, yeah you will be good to go with that ballast and an MH bulb.Cheers mate!!
