If you use the classic client and have UOAssist, the 'use item once' function it makes it a lot less of a hassle and a lot less work to grow plants.
I currently have 60 plants on three characters that I log in for a growth step when inclined to do more than locked down house plants. All I have to do is open the plant bag (won't work otherwise), then add them to the use once agent list by clicking on the closed bag icon. With the middle mouse button set up to display the next plant tend window, all I have to do is click the middle button to get a plant window, left click where it needs tending, and right click to close the window. Repeat as needed until done. One of the best features of UOA if your inclined to grow your own.
The worst part of growing plants is the hassle of building up regeant vendor quantities and buying them at the right time. None of the vendors seem to restock at the same time.
Try buying several 10's of thousands of regeants (Nightshade & Garlic primarily). In my opinion doing this part is the true Trial By Fire
of Gardening. The rest is fun.
Plants grown in a characters backpack only do a growth check if the character is logged in and its been 23 hours since the last growth check. If you don't play every day, this is the way to go.
Plants locked down at a house do a growth check at each days morning maintenence period and have to be tended each day or they tend to become sick. It's more work this way but is more fun.
My setup is at the house just over the bridge south of Luna on Chessie if you want to check it out. Go up the center stairs and use the teleporter on the right side of the hearth to go up to the garden levels.
Have fun.
