Which of the two options do you choose and why:
Option 1: 1440w over 40sqft giving 36w per sqft
Option 2: 1440w over 48sqft giving 30w per sqft.
The difference is an extra 2x4 of grow space. Do i go for more lumens or more plants? This is my first LED setup
More lumens will give you bigger, better, tastier, nicer looking buds. More plants will give you more bud(perhaps) but the quality will not be as good, always go for extra light, you will need it in flowering too!, 😁🌱👍
If you look at the PAR map for those grow lights you will notice that the PPFD drops drastically out on the edges so by stretching them even further you are reducing the light intensity across the grow area even further and your yield will suffer.
