I guess I just cant get the thumbnails to work for me....O well

Most of them are 5-6' tall but it's how wide they are and how many branches they have that requires larger trunks. We grow with lava rock because the grow rock is not strong enough to keep them stright. They just don't anchor right. Grow rocks are great for 99% of hydro growers but they don't work well for KBS style.
