Cans of paint, 1 block painted per can?

I know this is an old thread but I just got into Goo farming…have the farm up and was tinkering with configurations and I have one configuration that has a seed of 93% (really it should be 92.5% but the system rounds up) and a yield of 95%. Since there is no way to plant goo with a 100% seed…and 95% is the max you will always have at least a 5% loss of seed per planting. The 95% seed seems to have a 0% yield so it is only good for making a targeted color Goo seed. The maximum yield has an 80% seed…a 20% loss per planting…in exchange for a 220% yield…so about 3 or 4 particles for making spray. The configuration I am looking to use though is gives almost a moderate approach…almost at max seed with about 1 particle yield. I am not sure if the Farmer Epic affects Goo yield but with that in consideration it should be roughly 115% yield…so maybe 1 or 2 particles.

My thought is to set the target color and try to progress the color to the target and collect all the extra goo particles along the way and sort them for the pigment machine…maybe as raw fodder to get more spray cans out of it. The downside I found with this configuration is that the growing row is 7 blocks wide and only 2 of those blocks actually have goo on them so it is expensive to setup in terms of land mass. The loss of another 2.5% seed is the other cost…but at least it is only about 2 goo seed more loss per 100. Slowest I could get while still having yield.
