artificial light/indoors growing Vs. nartural light/outdoor gronwing

[Pananep]

Thanks guys for your input. Cindy, thanks once again for a great answer. I also have a rack with T5 lights. I just moved to a new house, and most of my neps have been placed under artificial lights until I finish their outdoor setup. I have sort of noticed that under T5 lights the plants seem to be growing a lot faster. Does this happen with your plants as well or is it just my imagination?
Also, I had a question regarding shade coth. I have an east facing backyard, and it recieves direct sunlight in the morning from about 7:30 - 8:00 AM all the way through until the late afternooon around 4:00 PM on sunny days. The sun gets pretty intense here. I have shade cloth that I believe is of 70-75% shade. I was wondering if this would be suitable for growing neps. Besides direct sunlight (under shade cloth) they would also benefit from very bright light. I have some neps like N. ampullaria and rafflesiana that enjoy partly shaded conditions, would this setup be appropiate for them as well?
Ok, thanks again for your answers. Hope to some more feedback soon. Later!
