PLAYER'S CUSTOM SPELL: Plant Growth, A player wishes to research a custom spell to have a plant grow faster Options

[Wacky]

Greetings all! Long time since I've last logged in to Dumpshock, but the Shadows have called to me again. I'll be GMing a bunch of new players with a couple of those use to the seedier side of RPGs (IMG:style_emoticons/default/wink.gif)

One such old hat wishes to have a custom spell that'll speed up the growth of plants (to reproduce the effects of Akira Miyawaki but quicker still).

He then asked if such a spell existed. I told him no, but also that he could create his own, custom spells given time and resources.

So that brings me to my question: What is the best way to design such a spell?

I found that it boiled down to one of two schools of thought/spells: Health or Manipulation.

HEALTH:
Were it a Health spell, the caster would have to touch one such plant and continue to do so until said spell was complete. The plant could grow, even a tree to full size in a short period of time, but soil quality would quickly deteriorate as the environ couldn't keep up with the new tree (all that mass has to come from somewhere after all).

So how much time would such a spell require? How would you have the Force affect the growth? What sort of water/soil would be needed?

MANIPULATION:
For a Manipulation spell, I'd look to the Shape Change spell for guidance. A metahuman can be changed into any critter so long as the body is within 2 of the target's form. One can use Health spells to boost/lower the body to get it within range.

What guidelines would you use for Body stats to change a seedling tree into a full grown one (say a mature oak)? What amount of time would it take to make this permanent or would it have to be sustained? Does the above soil/water problems still affect it or is this by-passed by the nature of Manipulation magics?

Feel free to leave me any opinion on the subject you have--don't mind criticism all I'm asking for is it to be constructive. (IMG:style_emoticons/default/biggrin.gif)
