The final results are in!

Heights:

  • HPS: grew about 14" above the soil. There was 22" of clearance to the lamp
  • Ind: grew about 12" above the soil. There was 25" of clearance to the lamp



These clones can easily grow to 24"+ in this amount of time, so next experiment I will lower the lamps 8"-12" (depending on power used) to increase performance.

Yields:

The container used to weigh is 32 grams. All weights were done with freshly cut WET flowers:



  • HPS: 195.9 - 32 = 163.9g
  • Ind: 109.9 - 32 = 77.9g
vanduction Reviewed by vanduction on . HPS vs. Induction + CFL flowering comparison Hi, this week I will be starting a comparison grow between HPS and Induction lighting. Question: Can induction lighting produce the same flowering performance as HPS lighting, while using 50% or less watts? The goal is NOT any of: - examine veg growth - produce maximum yield - try any other kind of experimentation Methodology: Rating: 5
