hey man for extra data points it's customary to measure leafs but also cross sections of stems and stalks (meaning you have to cut the plant down) . Just one question though : why only veg with these ?
@GrowInDirt, damn they're pretty cool folks though ! very generous ! before you go and add leaf size try searching for some scholarly articles about plants, they will usually include their measurements in there and you can see how they take their data points etc. i mean i suppose that's what you're after type of thing
@CRiSPrGrow, hi thanks for the advice! I will add the leaf size. To answer your question I still live whit my parents and they will not allow it. I can have my grow box because I did grow peppers in it.
