Question from a beginner to the hobby

Really not sure if it’s ok to ask this or not TBH, I got my first AIO bag and some LC from MYYCO and had awesome results for someone w no experience, so I kinda caught the bug n got 2 more bags and a monotub for when I wanna step the difficulty up, anyway like I said I used MYCCO for my first GTs and they colonized fast as shit n we’re ready in less than 40 days, so I go some b+ from MYYCO n some type Z from cube culture, bout a week later the MYYCO bags doin amazing while the CC bag has just a small nickel sized amount of mycelium growin, I guess what my question is and k hope it’s cool to ask-if someone cld dm me that’d be awesome too) im tryna find a good place for LC that isn’t too expensive, I’ve had good luck w myyco but 37$ for one 10ml syringe shipped is high, CC is 24 for one shipped, anyways I’m gonna order another few bags soon and I really wanna get some koh samui goin, I see them on a lot of sites, spore daddy,sporemd,thickspores, but it’s kinda hard to find feedback on misting these sites, if someone cld recommend some good sites it’d be hella appreciated! Loving growin my own medicine but damn there’s a lot of options out there, just curious who you guys tend to go w? Also was wanting to try some different AIO bags that are 3lb instead of 4lb, I’ve been using a whole 10ccs per 4lb bag(I know I know, still learning) how many CCs shld I use per 3lb bag?thank you everybody sorry for the long ass post!
