HPS vs. Induction + CFL flowering comparison
The little guys got put in the boxes about a week ago. They had been veg'd from clones, in a shared tray of potting soil, under a mix of bright HPS & MH. They were transferred into individual 6"x6"x7" pots with "supernatural" growing medium:
We like this medium primarily because it prevents overwatering and it's reusable.
Here are the plants after about 5 days:
HPS:
induction:
It may not be obvious from the pictures, but the HPS plants are a bit shorter and a bit darker. Both plans are showing the very beginnings of the buds.
There was a problem however: the temperatures in the cabinets are getting too low, despite the electric blankets:
Minimum temperature: below freezing!! I really hope this has not ruined the experiment. To solve this i installed 1500w electric heaters inside.
Once those were put in, the temperature inside remained consistent between 66f and 72f while the lights were out.
From here until harvest I expect to only post occasional pictures as the plants flower, but if anyone has any questions or suggestions let me know!
