That reminds me, I need to fertilize....
No wonder your plants looks so happy, Jim!
Around here, I pressurize a vessel containing rain water ( which we collect off the greenhouse roof) and use the attached sprayer wand to simply water everything, mostly daily. ( My greenhouse dries up very fast) Using daily fertilizer would be a bit more problematic here, since the glass walls on my much smaller greenhouse would be coated with salts in no time flat. In Summer outside I simply use a similar spraying wand, attached to rain water. Fertilizing outside is of course a breeze.
