has the best info. And for those that are on Instagram check out @grodan101 they have a chart posted in their feed that gives guidelines on how much volume to feed. Multi feeds of about 50-100ml per watering with a total of 10% runoff per day is ideal according to them.
I love when people say it should be done this or that way. What ever works for the grower is the right way. Canna also recommends top feed dtw, well guess what fuck that!
Tried str8 coco flooding 3x per day and I'm pretty sure it was my best run.
I don't know if its necessary, but when running F&D I would pour some nutes through the top of the blocks once a week.
Just make sure to get that waterfall effect in your rez for bubbles.
Check this dude calling out Grodan!!!
