Don't edge glue it unless you want to float it. We never edge glue t&G unless it's a floating floor. We aren't really installing floating floors any more. We're doing a lot of engineered hardwood for radiant heated floors. That's all glue down, but still no edge gluing. On solid floor for sure, no edge gluing. The boards have to be able to move with conditions. If you edge glue them and they shrink you could get cracks in your planks instead of gaps at the joints. Especially if the floor is nailed down. We're finding engineered flooring to be the most stable floor available. It also allows for wider planks to be had for less money. Be prepared though, any wood products prices are through the roof right now and our flooring subs are being told by their vendors that availability is very unpredictable for at least the next six months, possibly longer.
