Would 2 of these be enough for a 4x4 grow?

If you space them out right but I don't really think that will cover a whole 4 x 4 maybe 3 x 3. I have a 600 watt meizhi reflector LED grow light and it works good but I only use it for a three and a half by three and a half room so I have a little extra space. The power drops really fast outside of the 2 foot radius

I have a 32x32x64 tent do think i would need one or two of these lights?

Hello Friend, Thanks for your question. The coverage of this light is 2'x3'. I think one light could not cover the your tent perfectly. You can consider to purchase two or to purchase MEIZHI Reflector 450W( ASIN:B01J19ADTI) . Hope this could help you. Kind regards, MEIZHI

What spectrum are the leds? I can see IR 730nm, 3000k, 7500k, red seems at both 660nm & 630nm, but cant tell with the blue

Thanks for your question. You can also see the blue showing the in the 450~475nm which we have

Do I really need a veg bloom plant light switch or can I just use a full spectrum light to use the combined colors to get the same yield?

The two switches grow light is to save energy, when your plants are in veg period you just turn veg on but not full spectrum to save energy.
