Hey guys, its me again and its question time
Im going to be doing a small veg tent, and initially i was going to buy a 300w cfl, then i thought 300w cfl would be a bit silly when a 250w MH would kick its arse, so then i started looking for a digu ballast, reflector and bulb combos......arnt cheap.
Then i thought of the CMH combos and the reviews they have been getting. So now im thinking of slowly getting a couple of these between now and summer, and sticking a couple in the air cooled hoods over the comming summer months, but try 1 out in a veg only tent while i try and find a good mother.
So without continuing to ramble on, i read somewhere that the daytime ( veg ) bulbs are a bit shit. Now i dont know fuck all about par, lumols, and the other fancy terms associated with light spectrums, but ill copy and paste this 2 tid bits and see if anyone can uncomplicate it

For £225 collected locally or £195 online i dont mind investing in something that could possibly compete with a 600w mh/hps for the summer months and use less elecy , create less heat and grow some fantastic bud, but will perform better than a 300w cfl or a 250w MH.
Rambling again. Just bare in mind the veg tent is a Secret Jardin Lodge L90 90cm x 60cm x 135cm, and the main tent is a 2.4 x 1.2 x 2m.
Would 2 of these 315 cmd kits cover 2 plants in my fliwer tent, and would 1 of these kick ass in my veg tent ?
