Decided to throw the girls under the 500w MH bulb and transition them into the flower process. This Green Crack Auto was already flowering under the 100w so I figured why not flower another girl with her and bump up the juice. I know Autos can have up to 20 hours of light but pretty sure that wouldn't be good for a photo so 12 hrs it is. We will see how the difference is "watts vs hours." We have created a hidden experiment within the grow!!
