new cob?

hi, new to growing. do i use new cob or older?

What's your budget and space

I heard the white cobs are better for flowering and the yellow ones are for veg. These are the beasts I use with great results.

u think red then>

I think @mo841 was trying to be funny @MasterMiller was trying to help but needs to know what your budget is. But ultimately need more info than that what your grow area 2x4 4x4 something else? are you going for a veg/flower setup or separate veg/flower? not really possible to answer your question with just COBS. Have you done any research? COB just means chip on board can be anything from http://www.rapidled.com/10-solderless-led-low-profile-rooting-kit/ to http://timbergrowlights.com/300-watt-cree-cxb3590-6-cob-grow-light-kit/ and lots in between

i thank you, i found what i needed fgt grow light. on timber grow site. case closed.
