It’s all about balance. The main thing you have to balance is lights and nutrients.I want to buy already large plants like you did. I do not want to spend time trying to grow them. Too much time and effort.
Do you know what I need to look for in flood lights? Specific lumens, type of light, etc?
The other big thing I am worried about and did not mention algae. My tank is near a window and suffers from algae. I plan on putting up curtains for the new tank. Wont running flood lights like these create a ton of algae?
The more light, the more nutrients you need or you’ll have an imbalance where algae can take over. Since your not doing ferts or co2, cover your windows and control how much lighting you get.
I would go with husky pendant LEDs from Home Depot that I posted. Not sure if you saw that. Proof of concept is in that photo.
