Influence of reduce light levels by increasing copper sulfate concetration in the spectral filter on total leaf area (LA), average leaf size (LS), leaf fresh weight (LFW) and stem fresh weight (SFW). Control (water) filter grown plants were shaded by cheese cloth to match the light levels in both control and corresponding copper sulfate filter.
