I have wanted to do a targeted-wavelength T5HO grow and use an icecap ballast to rock 356w T5HO in a 4 tube 4 foot unit. I have a feeling for fluorescent growing that this would be the way to go, given that the peak range for each phosphor is wider than the typical narrow emission band of LED, and thus it would cover supposed 'support wavelengths' as well. Also, I would like to see narrower tubes, T4 or T3.Quote:
