So a tub whatever kind? that you put sprayers in all seem to leak around the edges. I have tried roughnecks and others but still no luck. What would be a fix for my problem? FYI I build all my pvc/sprayer lines ect... Also I find it hard to grow more than a few clones to 12" tall where all stay equal in size.. Seems even when you watch em every day that when you start to take em out at 12" tall you find you missed the one or two that took over but maybe I am half blind and just need to be more careful on that one.. But want a tub that won't leak without using a foam that hardens around the under edge of lid because other than that nothing has worked. Thanks for help.
