Started these seeds using the paper towel method on a heat mat and the seeds all popped within a day. After 2 days I transplanted the seeds into small growcubes and into the clay filled hydro pots in nutrient free water in my bucker DWC system. After a week the seeds sprouted and look to be growing nicely albeit a but slowly as it is middle of winter here,
Mate you need to switch on both the red and blue spectrum.
Plants react to blue light in a way that makes them think its very intense light they are under so they dont stretch as if you would have applied more red light.
If you wonder why your plants arent growing very tall, then thats why.
If you want them to stretch alot, then you should apply light from the 650 nm spectrum and up - Infrared and basic far red light is good for making plants stretch tall.
Happy growing 😎
