I have a tray of small six packs with baptista that I WS'ed.. been out in full sun and has not dried out yet.. depending on which ones I will use only a couple of the large ones.. 5 or 6 of the smaller ones .. but always expand them first... I usually put a little coir on the bottom then add them .. so they don't fall through the drain holes ... granted we haven't had many days of dry weather yet.. but we did have some high 80's already.. they always help
