Bamboo Flooring Installation Gap for Expansion

Just about to start laying my Bamboo down.Instructions say to leave a 3/4" to 7-8" gap between the outside boards and the wall. My baseboard is only 1/2', how the heck are you supposed to cover the gap up, who has 1" think base boards?

My thoughts are these things expand the most with high humidity correct? Right now before winter my humidity should be at the highest and it will typically drop over the winter period, causing shrinking. Now I put a humidifier on my furnace about two weeks ago to try keep my humidifer level throughout the year. If I make a 5/8" to 1/2" gap, do you think that would be sufficient? I couldnt see it expanding much, if anything I would think it would shrink...

technically, that's the directions.

however, and keep in mind this is just my opinion, i installed my hardwood with just under a 1/2" gap so the baseboard would cover it. the sales pitch with the large gap is to use quarter round to fill the void. i really didn't like that idea and seriously don't see how the floor is going to shift 7/8". seriously, that would rip the staples out of the boards if it really took place.

The wall board should be an inch or so above the floor, maybe yours isn't. I'd follow directions, the manufacturer should know the characteristics of their floor. You're supposed to have base and shoe or quarter round. Many believe it doesn't look finished without them.

Be sure to undercut the door jambs too.
