I grow in soil, and as far as how much water I don’t know I don’t measure it

aside from mixing up a gallon but from there I pour it into a solo cup to feed with. I only mix a gallon because it’s easier, not because I intend to use it all.
Only time I water to runoff is the last time I water before putting them on the res. And even then I water very slowly a little at a time over the course of about a half hour and I stop when I get the first little dribble of runoff out of the bottom of the pot.
I’m still figuring it all out myself. So take it with a grain of salt. As far as what to order, I’d say grab some Mephisto beans. They have a bunch on sale for the new year right now on their website. Fast shipping, generous freebies, and some of the best genetics around.
