Been thinking about this for a few years.
I was trying to figure out an easier way to water my plants when they are in the sunroom for the winter.
So I ordered some trays from Grower's Supply and next payday I'm getting a Shop Vac to suck up all the water coming out of the pots into the trays. Otherwise I had to carry all the plants (except the big guys) to the kitchen sink several times over the winter/spring.
With the job I have now, I don't have the luxury of all that time. I figure this should cut my watering time to a few hours each time. I think I retarded their growth because I didn't water enough in late spring before they all went back outside.
Now if I can only figure an easy way to keep those pesky spider mites from attacking my Lobivias/Trichocereus when I don't have time to look.
