Naw you can do the bamboo stakes just FINE. Put them in early, as soon as they can stand up on their own. That minimizes root disturbance down the road.

Although come to think of it, if you can find INERT stakes, made of PLASTIC, like pieces of small gauge PVC pipe, that would be better, since bamboo ones can rot. Plus you can run PVC through the dishwasher to sterilize it for the next grow.

But I think bamboo would still be okay. I use them in soil but it's a different ballgame.
