Pro tip for the day build your own. Led specifically cob led's are a great way to save a ton of money on your electric bill and making the cob engines yourself will save you even more. Everything here at Nova inc. was vegged under cob led's with alternating 3500k and 5000k spec and driven by a Meanwell 1400 mah driver powering in rows of 4, perfect for veg and they can also be finely tuned for flower. Diy cob engines are very easy to put together and install all that is required is some basic knowledge of electrical work and the Will to do it and as always with electrical work if your not sure consult a pro. Remember electricity kills be safe my peeps.
