Papa_Tanswered grow question 9 months ago At first when I saw this set up I couldn’t figure out why this set up wasn’t working.
I think you your limitations are down to your lighting. Those neon lights just aren’t powerful enough to promote great bud growth.
I don’t know how much PAR or micromoles those lights are pushing but I doubt it’s pushing anything close to 900 PAR/PPFD. Which is close to what you should be pushing during flowering. CO2 supplemented grows can even take up to 1,200 PAR.
Also your light doesn’t look like it has any red spectrum light. Which definitely helps in bud production.
Anyway that’s just my observations.
