<chuckle> I think the refresh button or something got away from you. We've all done similar.
I'll let the lighting pros get to specifics with you regarding your light questions. Looking at the light you linked to I'm not so crazy about the gooseneck lamps...but, if I was going to go with one, I would go with the 100 watt version....within reason, I don't believe you can have too much light. I'm using simple 5000k Walmart LED shop lights and they seem to be working well while my plants overwinter indoors (I usually keep them outdoors). Some of the square panel lights are very good, economical choices, too...."Mars Hydro" and "Yescom" are two brands that people speak of often...I think the "Mars Hydro" is a click or two above the "Yescoms" in quality. But, these are intended for hanging from above...I'm not sure that would work out for you. The blue/red lights grow plants really good, it appears, but the plants look horrible when you look at them under those lights (IMHO). I grow the plants for my enjoyment but if I was to be doing this for production of plants to sell I'd probably opt for the deep purple-looking lights.
Do you intend to plant the plants separately in individual pots and sit those inside the terrarium? Or, are you intending to simply use the bottom of the terrarium as your "pot"? Hopefully someone else will come along with some good lighting info for you. Have fun!!!
