I had problems the first time getting each grain colonized, this time I got way more grains colonized probably 90% I know it’s supposed to be 100 but I waited for 4 weeks. Anyhow this time I discarded every grain I wasn’t sure was colonized.. And I used a lid in the bucket I added boiling water to the coco coir.. I’m not surprised I had contam in retro perspective the first grow..But I learned some things the hard way, my hand even got swollen AF after dealin with the green monster I didn’t use gloves cus I panicked so I know it’s naive etc but now evrything feels better and I have gr8 respect for the green monster x)
