Fairily new grower here. On my third go indoors. I do a lot of reading so I've been able to navigate hurdles so far without too much damage.
Ive had:
heat stress
cold stress
mites, thrips and aphids
hermies got a whole crop
bad clones/ good clones
running too many strains at once
starting half cocked so end up chasing problems
So I've been through alot so far. The hermie crop - was too much to sort out. I was going to lose them all so I ran em out anyways. I needed some stock to practice extractions. I ended up with some awesome material over 20 %. Not bad for 10 strains all at once, and seeds. Got 1.7 lbs per light.
Anyways there you go - that's who I am.
