Grown in APotforPot.com 5 gallon kit with no additional nutrition added. Easy germination within 24 hours in a glass of water with plant development on target per ILGM. Slight light burn early in the grow (see week 4) with no apparent lasting effect.
Total water used 52,150 ml / 13.8 gallons.
Sequential harvest to:
1. Collect samples at various stage of harvest to determine differences in effect.
2. Cut main cola at the beginning of harvest to open middle and lower flowers to light.
3. Cutting main cola to enable lowering light to increase intensity for green leaves.
Lessons learned
1. Additional defoliation to eliminate small, interior branches. Small branches create a disproportional amount of work to trim and dry in relation to the yield. Play closer attention to defoliating smaller branching during vegetation growth to aid later harvest and drying.
2. Cut large branches just below first branch to enable hanging at 'Y'.
