12 Mistakes Almost Every First-Time Grower Makes

Nearly every first grow hits the same handful of problems. Knowing them in advance is worth more than any piece of equipment.

The list

  • Overwatering — learn the pot-weight method instead of a schedule
  • Overfeeding — start at half the bottle's recommendation
  • Ignoring pH — a $15 pen prevents most 'deficiencies'
  • Buying too weak a light — the number one cause of airy buds
  • Undersizing ventilation — heat and mold follow
  • Harvesting too early — the last two weeks add real weight
  • Drying too fast — 10-14 days at 60/60, not three days in a closet
  • Skipping the cure — two weeks minimum, six is better
  • Changing five variables at once — you learn nothing
  • Not checking for light leaks before flowering
  • Growing too many plants for the space and the legal limit
  • Not writing anything down

The meta-mistake

Doing too much. Plants are resilient and mostly want to be left alone in stable conditions. Most damage in a first grow is inflicted by an anxious grower, not by neglect.

Frequently asked questions

Should my first grow be an autoflower?
It is a reasonable choice for speed and simplicity, but photoperiods forgive mistakes better because you can veg longer to recover.
