An irrigation system??
 

Watering is probably the most labor intensive aspect to growing plants in a greenhouse. Years ago when I was working at a commerical grower the cymbidiums were being irrigated through a drip line system.
With my greenhouse being as crowded as it is I have reached the point that I hardly ever water the pots. My plants survive on the rain I provide with my pressure sprayer twice a day. While great for growing plants it forces me to segregate those that need dryness for flowering and with my space rather small such is almost an impossibility.
So I was wondering if setting up a drip line system in the greenhouse and even installing a solar pump system from my r/o unit to feed the greenhouse is a practical idea or just more work than it is worth??
Any thoughts?

I think that a drip line would never have worked in my greenhouse due to its size and the "esthetic" I wanted (natural looking environment) but with a smaller "bench growing" set up it could be a boon.

My watering system is overhead sprinklers, by default. The system was supposed to be mainly underground with pop ups at ground level, but, I ended up having to plant the greenhouse before it was installed, and then they had to do it overhead. It turned out to be better in one respect: most of my hanging stuff gets hit by the spray. But it does have a negative as well: the spray hitting the greenhouse wall does cause some algal growth that has to be regularly cleaned.

I only use my sprinkler system when we are out of town. I found that if I use it all the time, I am less likely to go out to the greenhouse on a daily basis to see how things are going, and small problems tend get out of control more quickly. Like pests, or a plant that may start doing poorly that could have been caught if I'd been out there more often. It only takes me about 20 minutes to water the GH, I think its time well spent.
