Kingbrite or Meijiu Questions for 39"x39"x70" tent

2 dimmed down rectangular 240 W lights (having L301B or L301H diodes) with red kits or one square 300 W light that increases PPFD on the tent's sides?

Hello,

I am looking to purchase a light for my 39"x39"x70" (3.25 ft x 3.25 ft x 5.83 ft) tent. The tent area is 10.5 sq ft. or 1 m^2. 30 watts * 10.56 sq ft = 316.88 W. I will use the light for the entirety of the grow cycle. Upon further consideration, I have decided to narrow my search to Kingbrite & Meijiu Lights.

1) Would I achieve better quality/higher yield by increasing the PPFD towards the tent's sides if I installed 1 rectangular 240 W lights & 1 125 W light (375 W total having L301B or L301H diodes) with red kits instead of one square 320 W light?

2) Is there any benefit to getting a light having IR or UV features?

3) What is the recommended payment method on Alibaba.com to protect the consumer? Credit card? Paypal?

4) How much is Customs to Vancouver, BC, Canada?

5) Any other tips when buying off Kingbrite or Meijiu on alibaba?

I looked at those as well. Next year for me. The two 240's would do great in that tent. You'd have all the light you'd need for a tent that size.

There benefit but j have to controle it 660 is enought far red . I believe that 3000k +660 will give a perdect spectrum for flowering enhancing
