I was pleased to read that the new lights will be compatible with the old and it will be possible to daisy chain them.[emoji3]
I'm looking forward to the day I can link my 2 x 75w HS1's to 2 x 150w holographic series. 75's starting plants off 150w finishing !Mmm 450w of GN diffused light( I can really notice a difference in plant health with the properly diffused spectra)nJust hope I will get the space ready sooner rather than later.
