Well like I said mine was random, I got it with stickreeds and melons crossing, I believe. The low light seems to make sense though, I may have to make a low-light crossing room to test it out.I haven't been playing much since I started working on AgriculturePlus, I badly want those herbicides working for crossing, I've lost too many things(including 1 of the redwheat I was able to cross out of the original) to weeds
weeds can be minimized with lower growth (weeds inherit their parents growth stat) and higher resistance(takes longer for weeds to overrun plants giving you time to catch it) if you want low maintenance plants. alblaka said himself that red wheat is picky about its light level.
