I have successfully used the old paddling pool trick when I was first starting this garden and had plants and divisions to nurture before I could plant them out. It's easy enough to prick holes in teh sides to stop water getting too deep in the event of heavy rain.
I did invest in one of those pod systems which has small pipes coming off and pegged into individual pots to keep my greenhouse going but I only used it once. Very fiddly.
These days, I gather all my pots, window boxes and hanging baskets into an area at the back of the house and set up a sprinkler system on a hose and on a timer so it goes off during the night. It works brilliantly so now I've bought a Y connector for the outside tap and have a second hose and smaller sprinkler going into the greenhouse. Simple, inexpensive and effective.
I also gather houseplants up and give them a shower to remove all dust from their leaves and to make sure their compost is thoroughly soaked but drained. Then I place them in the bath with a bit of water and close the door. They make their own Little micro climate and I come back to very healthy plants.
