If your using a ph meter or dissolved solids meter this is a must have. Not cheap but accurate. If you want your grow to turn out right you need accurate info on your water ph and fertilizer strength. Don’t think you can compromise here. Not cheap but reliable.

Everything sealed and new, just as described. Make sure to read labels and instructions printed on each bottle. Would recommend to anyone(using with non bluelab equipment and its working great)

Do believe the shipping... it really does take that long. Packaged up soon after order but took week to actually get to carrier and shipped. Not a big deal. Why lie though?
