I have a few questions regarding lighting..I was thinking about possibly buying a 2 pk of 23W, 1600 lumen daylight CFLs to grow nepenthes and sundews (I only have my N.vent..going to purchase more CPs along with the lights)
I'm pretty confused...here are my questions ;
1.Do two 1600 lumen bulbs together result in 3,200 lumens? Or are lumens not cumulative
2. Do lumens even matter? And if they do , would these lights be sufficient by themselves?
3. If not, what (cheaper) lights would you recommend? These are for a single terrarium filled with a few potted plants..approx. 2' x 1.5' x 1' (very inaccurate guess..I'll mesure later)
