All of my Botany Twerks

Old "nutrient" items were in my opinion a bit snowflakey and didn't work
well with the new irrigation changes. Now you can dump a bunch of
nutriment into a bucket. Also did not want to create new types of
reagents for L4D and Robust Harvest so I used existing chemicals that
had the same described effects.

Diethylamine is a powerful fertilizer chemistry usually would have to make, it also kills pests.
L4D: 3 radium and 27 nutriment per bottle.

For clarification. the old system had the trays have a yieldmod and mutmod variables. These acted as multipliers and were either 1 or 2. Th last nutriment bottle you entered changed it from EZ:1,1, L4D:0,2, RH:2,0 and were multiplied against the plant's own yield var.

Now they effect the plant directly like all the other reagents do. Might need some tweaking though since you could just spam RH into a tray for max yield.
