12 Mistakes Almost Every First-Time Grower Makes

By The Budometry TeamPublished Updated

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.
