@Celene, save your $85 for that watering can.
You can make a DIY watering can using a large plastic container with a handle, similar to the ones use for detergent or cat litter.
Save the lids from about 3 of the same type of container. Drill holes in the lids - smallest holes in one lide for fine watering as for seedlings, medium holes in another lid, and larger holes in the third, Interchangeable lids!
Of course, if you'd rather not DIY, you could always send me the $85, um I mean 85 acorns and I will gladly send you one of these fine plastic 'watering cans' complete with 3 lids.
