[RMVX ACE] RA FARMING, WATER ONLY GROWTH?

I've been working with Eshra's farming script, but am having some trouble with some of the absolutes involved. I can get a plant to grow all on it's own to the final stage, or die and go black if unattended, but is there a way to make it so the growth stage will stay at it's present state until it is watered? So that a plant that has 7 stages will need to be watered 6 times before it can be harvested instead of growing on its own or dying while you're off questing.

I know there's a Water Start Add-on, but I can't get it to work properly. I need a way that each stage requires watering. Once I water the seedling it just grows into an adult or dies if a minimum is set.
