300w kit
Written by Daniel Z. on Dec 1st 2016

Arrived fast was very easy to put together once I made a frame. The harvest results were more than expected now that I have my first results I believe the next one I'll maximize the lights potential and will already have paid for the lights. I will definitely be buying another kit for perpetual cycles.

Very satisfied with this kit

It came as advertised and the wiring was well done including adding the power switch I requested. PAR readings are fantastic in my use and I would recommend them to anyone.
