These are the strains im growing with their flowering times next to them: Critical Yumboldt(7-8weeks), Fast Nevilles(8-9weeks), The church(9weeks), WW X BB(7-8weeks), Sugar Black Rose(7-8weeks). My question is, i'm thinking of just harvesting all my plants at 9 weeks since one of my strains ends at that time and i want to pack on as much weight as i can on all my girls. Is that a good idea or does that sound like i would be over-harvesting some of my stash? Anyone have any input on this matter? IF so + REPS. P.S. I don't have the money to invest in a microscrope to check when to harvest.
