Those were the three I was going to pick out quick lol.. Upper echelon?? idk?? If I were Eraserhead I may take offense to them being put in the same category..
But this is 2015 folks.. Being the betting man that I am, I would be willing to put a wager that this will be the year of the commercial COB unit and expanded use of the 315 CMH (don't need to be Nostradamus to make those predictions right??).. I'm piecing together my own Veros so that CMH (not new tech by any means) is looking like it will be the next piece of hardware, but there could be something better by that time (still looking forward to whatever A51 does with that 10w fixture we been drooling over) The rest (lumigrow, heliospectra, CLW) are going to need to up their game to stay competitive..
Or they could team up with Advanced Nutes and have a "grand-master grower" bundle package.. all to be had at the low,
low cost of your right testicle..
