Yield machine max 3 weeks in.

Here is a medical grower about 3 weeks and 4 days into his first grow, using the Yield Macjine max grow box.  
Some people worry of heat in this grow box, there is no heat issue, this cabinet is totally stock.  Growing extremely nice, only changing water and adding nutrients once a week, that is all you should be doing!  Thermometer placed under grow light will read upwards of 20 degrees hotter from UV and infrared LEDs. Check out some progress below.
