Can I use a standard M/H bulb in a 400 w HPS lamp from HTG or do i have to get the conversion bulb?
if u want to veg get 6500 k or 6400k t5 lighting systems
if u want to flower get the digital 400 from htg with the basic bulb
u can also veg with the hps....dont believe all the hype
use cheap t12 till they are 8 inches tall and then convert to either t5s or your hps
the conversion bulbs lose a ton of lumens .......check the conversion lumens for a 400 and the lumens for an hps 400.....not even close
i used a 600 hps conversion to mh and its a joke.......1/3 less light using the same power
You can fire a regular 400W MH bulb in a 400W HPS ballast. This is fact. The reverse is not true.The reason I ask. It would be convienent to go to Lowes but they dont have conversion bulbs.
thanks, i looked at homedepot today and both bulbs require a diff ballastYou can fire a regular 400W MH bulb in a 400W HPS ballast. This is fact. The reverse is not true.Call up HTG and ask them; they are very informative!
