ok, what about watering it wouldn't evenly watering everything be a problem? unlkess I got a table that was tilted downwards or towards the middle so the water goes al the same place.
I like this idea, as I have some plants outside in felt pots and wanted to get another bed for them.
I love the felt pots for sure, but watering every day, twice a day, is a lot.
With a grow bed, I think a water drip line could be established, and save water?
Or since it is one solid whole medium, can you use a watering can with a spout that spreads the water out?, and that way you can load up say a gallon, and water evenly over the entire bed in a soft drip way.
As for a ballast, I only work with CFL's and LED (so far). From what I've researched, lumatek is going to be the best for digital ballasts, for a few reasons I guess. Non-digital ballast are pretty solid, just get the job done from what I have been told. Not sure on a quality brand name for those, but I know they don't have all the electronics that the digital ones do, which for some may be better than a digital. Just trying to help.
