I have a new grow rack, and I'm trying to work out how to light it.
I currently have access to:
a 20W compact fluorescent
an 8W fluorescent tube
Which obviously isn't going to be enough! But what is 'enough'?
I'm planning to grow lowland nepenthes on the top and highlands on the bottom. I've heard highlands need more light than lowland nepenthes, but how much light is this? Is it possible for me to have lots of small lights to add up to the wattage, instead of 1 big tube light?
I'm looking for measurements in Watts.
