Yup. Rockwool can be tricky. It was the go to medium back in the day. Once you get it...it gives very similar results to coco coir. Top drip manifold and run to waste is how i found both these hydroponic mediums do the best. And like coco coir....when starting out with small transplants with small roots....a wet dry (almost) with rockwool gets yiur root structure going quick. The main thing i never liked about wool was reuse and or disposal. Figured out quick that wool slabs wasnt ideal for reuse and getting rid of that spent shit back in the dark days of growing was paranoia and a bitch.I will do my best. I've had some teething problems at testing the first run of bagseed and thats in another thread. Its a lot of firsts all at once and at this point i've decided the weakest link (together with my own mistakes, admittedly) is rock wool: its just too temperamental for me. Too much water and they choke, too little and it dries up real fast. Honestly I had better & faster productivity dumping them on a window sill in regular garden soil.
I'm swapping out my rock wool stock for Rapid Rooters for the next lot of seeds. Cali Connection Larry OG and not cheap so must get it right from the off. Lessons learned already.
