DAY 1 (06/03/2020)
The seedlings started growing tonight after 4 days since they were planted inside the rockwool cube (02/03/2020). They are under a 23w CFL until they are a little taller and start to make the first 2 leaves. The distance is very small from the light to not get them too stretched. Feeding just water now. I already prepared the RDWC setup with a 60 liters box (0,6 m x 0,4 m x 0,25 m) for 3 plants. The grow tent is 120x120 cm. The light will be a Sylvania 600w HPS powered by a Gib Ligthing LXG Timer 600w Electronic Ballast. Since it is dimmable I will start with 250w and increase in the first weeks until reaching 600w. The ballast has the Sunlight mode which increase the wattage of the lamp during the first hour and decrease during the last to simulate the sun cycle.
DAY 5 (10/03/2020)
Seedling are growing well. I started RDWC yesterday and put 25 liters of water with 15 ml of FloraCoco Grow, 15 ml of FloraMicro,15ml of FloraBloom. I also added 5 ml of Great White Mycorrhizae to strengthen roots. The water from my tap is 40 ppm , the water in the reservoir is 500 ppm. Increased power light to 350w. Temperature and Humidity when lights on: 23°C and 35%. Added a humidifier inside the room to increase humidity.
