Heads up: I made the mistake of manifolding these short growing hybrids so don't go thinking it's the best option for yield, I wasted a lot of light. These would be great for sea of green or a topping with LST!
Used a drop of 13 Essentials to help sprout and then soaked the rockwool cubes in 100PPM tap water. Using a small low watt T5 on top of a humidome.
