hi guys im gettin another light today a 400w mh i think. i already have a 600w hps what im wondering is should i run both of these or should i just run the mh as im only in 3 weeks of veg.
again, C.M.Hi already have a hps so its a veg light im wanting to boost there growth.
so mh or cfl?
What I like about the CMH conversion bulb is that it can be used all the way through, from vegetating to flowering.if your getting a 400, get a ceramic metal halide bulb, just know you run it on hps. Use the cmh for veg and then you can use the hps for flower, or if you want to go big, use both for flowering.
that's fine, but with a CMH, you would run it on hps, The temp around a 400 cmh is less then 100 degrees, so you can get it real close to the plant and the spectrum is one of the best available, I've noticed way more budsites since switching to this for veg.what about a switchable ballast??
it needs to be a magnetic ballast, either switchable or just hps.ill see if they have the cmh. do i need to get a switchable ballast can i not just use one i get with it. my contactor can take another 600hps
