A test and review of the new Viparspectra P1000 LED grow light. Tested in a 2 x 2 or 60cm x 60cm space at 25cm hanging height it delivers 1.89 umols/watt usable PPF to the grow canopy and 533 umols average in a 2x2. A very good result for a very cheap light like this. It is a good quality build as far as I can tell. The spectrum is 4000K CT equivalent or a neutral white with 17% blue (good for vegging and for flowering).
