To be fair he had a stomper yield just before christmas with his 630 cmh.  Yeah but im a bit a skint right now was my reply tell ya what he says ill lend ya the cash and buy you one.

Normally I'd say check out G&H for a CMH set up but they dont sell the two reflectors I'd recommend, the cheaper is the maxibright focus remote reflector which costs about £60,

the other reflector is the dimlux alpha 98 but that costs near £100. as for what ballast to go for, one of the most reliable is the maxibright 315w daylight ballast & there's been very few

mentions of folks having problems with them. 


as for what lamps to go for, there's three, there's the 942 Mastercolour lamp which similar to MH & are good for vegging with if running a two lamp system, next up is the 930 Mastercolour

lamp which is similar to HPS, also just point out, you can do a full grow with just a 930 lamp but depending on your plants, they might stretch a bit when going from 18/6 to 12/12,

lastly there's the 930 Green Power Elite Agro lamp which is a specialized enhanced flowering lamp with a far red light spectral output (techy talk) lol


as for the price of the CMH lamps, a 942 & 930 will cost you close to £100 from a grow shop but you can get them from lighting suppliers for £72, as for the 930 Agro lamp, they usually cost

close to £100 on ebay. if you go with a full 315w kit, you can get the maxibright daylight ballast-focus remote reflector-930 Agro lamp for £240 & if you go with a two lamp system (942 & 930 lamp)

it'll cost about £312 + p&p.


I dont know anything about the ruck thermal fan but if a fan is on a variac & your using acoustic ducting, then there shouldn't be a lot of noise, have you tried wrapping your fan up or putting it in a box

& insulate it with either a blanket/sleeping bag/insulation foam (Leepy style - search the site) 


if your only running one 315w, I would check out either the 5" systemaire or 5" ruck/can fan, they both move a lot of air 320/350 CFM & both cost about £75 & are highly reliable.

but if you intend to add another 315w set up in the future then I'd suggest you get a 6" fan.
