Emersed plants in a nano - possible to have too much light?
I've been growing dwarf HC semi-successfully emersed in a nano (3.5 gallon) for about 3 months now. While I've seen some serious progress and growth, after looking at other's emersed setups, I think I could be doing a lot more to speed up growth and spreading. It seems like others have seen substantial growth after only a few weeks.
Here are some questions I have that I as unable to find answers to via other's threads:
1. Is it possible to have too much light? I have gotten a bit over-ambitious and now probably have 70 watts over my emersed nano setup. 3 separate desk lamps, all aimed at different angles/areas. They are on a timer, approximately 9 hours of light each day.
2. Will I have better luck keeping the setup covered or uncovered? I've experimented with both but am fearful of the tank drying out too much if I leave it uncovered for an extended period of time.
3. I use a spray bottle to mist the plants at least one a day. Is this beneficial?
4. If I were to put in a few inches of water and start dosing excel, would I speed up growth?
Any other suggestions in addition to these questions is appreciated! I would love to start putting actual water into this tank soon and move things along. 3+ months of misting and blinding lights is growing old.
