I’ve just recently found out about windowfarms and I want to get started building one as well. I have three huge windows, all together about 5m wide and 1,8m high, the only problem is that I don’t have any direct sunlight and I can’t find any place to buy the right CFL bulbs. I’ve read on the website that I need bulbs with a light temp of >5500 K but when I google this I can’t find a single website that sells them. And are there any other requirements? Like wattage maybe?
So does anyone know a website or a store, preferably in Amsterdam, the Netherlands, where I can get some of the right lightbulbs?
Many thanks in advance!
