We have consulted in one way or another for over a million square feet of canopy. We have designed huge facilities and we have rescued the smallest of facilities. Every single consult gets the same setup. We have tested method after method and know what works every time. It is very simple.
1) Automate your watering. Hand feeding is not consistent.
2) Use 2 gallon pots with coco. Coco is forgiving and does not need a large root base to produce big yields.
3) Feed DAILY at 2.3-2.5 EC (1150-1250 ppm @ 500 scale) with 20-25% runoff. This gives the plants what they need every day, keeps buildup and ph in check, and brings oxygen to the roots.
4) Give your plants a proper environment. 75-80 degrees, 60%+ humidity, plenty of light and airflow. Of course you can dial in your environment to be more ideal but these parameters work great.
Follow these guidelines and you will see the results.
