cant really get a digital ballast as they start at like 200$ here in australia, but i found mh conversion globes that run in hps ballasts so problem sorted
thinking of getting a 400w hps light can i put a 400w MH bulb in it?
or should i get a 400 MH ballast and stick a 400w hps in it
not sure how the ballast works, hoping someone can break it down for me
also im growing autos so is it worth having mh on them for 3-4weeks then hps for the rest or...
the answer to your question is no since you there will never be a light which produces as much as the sun, all you have to worry about is heat killing them
in a setup like that its all about ventilation
this may sound dumb but if you never ask you will never find out
if i mix a nute that is 1-1-1 with a nute that is 2-2-2 will this make the nute 3-3-3????
is the 4 fans pushing a total of 140cfm in and 140cfm out not going to be enough? if it really gets too hot ill just add like another 4 fans or something..ill do a dry run anyways with just the fans on and lights and see what temps i get and work out weather or not i need more cooling
250w sunbrite is bigger?
