Soil Grown Marijuana Indoors – Container Comparison

All three plants shared one 4’ x 4’ x 7’ grow tent during the vegetative phase.

A single 1000 watt MH bulb in enclosed and vented hood lit the three plants.

  • The light cycle for the vegetative stage was set to 16 hrs on and 8 hrs off
  • The vegetative stage for all three plants lasted 24 days

During the flowering stage the three plants were grown in a small portion of a larger room.

  • All three plants were under two 1000 watt HPS bulbs in enclosed and vented hoods about 7’ off the floor.
  • The plants were grown with an alternative lighting schedule of 6 hours light and 18 hours dark.

Although this was not a light study, it was noted that the yields of each plant were at least 50% less than plants grown in using same methods with standard 12-12 flowering production.
