Hello!
I'm new to the hydroponics world and I'm doing my vertical growing system whose dimensions are 300 cm x 150 cm (area= 450cm2) with a density of 105 lettucce per tier. I have 2 racks whit 3 tiers each one. The distance bewteen NFT channel and the roof are 40 cm.
I'm reallly confused about the lights. I want LED light whit full spectrum and 150-250 PPDF (umol/m2*s) average but I don't have too much money to spend. For my dimensions system I will need a lot of LEDs.
Do you know where I can buy cheap led lights with those characteristics? Would any link from Aliexpress or Alibaba also work for me? I could not find a company that sells cheap with quality.
Your answers would be of great help! Thanks
