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:

Manufacture 2 identical growing cabinets. The only difference is the lamps installed in each cabinet.

Put in each box an equal number of veg'd clones that are ready for flowering. Feed & water the plants the same during flowering.

At the end of flowering, compare the quality & yield of each cabinet.

The lights:

Cab 1) HPS with magnetic ballast.
- Rated power: 250w
- Actual power used: 315w

Cab 2) Chinese induction lamp
- Rated power: 120w
- Actual power used: 118w

Cab 2) 2 x Sunblaster 2' CFL
- Rated power: 24w
- Actual power used: 20w

*note: The CFLs may be added because my actual power use estimates were off (I expected the induction to consumer more than rated) and I wanted to get closer to 50%. Feedback on this decision is appreciated.
