I'm using a bestva 2000w LED, actual draw 390w.
BestVA and King LED sell the same products. My first light was the King X6 Dimmable 1800W COB LED Grow Light. I was not enough for a 2' X 4' (60 x 120cm) tent, even at full power of 315W. The COBs only occupied a small portion of the light's surface. With four plants in the tent, the two next to the walls produced 40% less than the two closer to the center of the light. The cost for the King X6 is the same as the Mars Hydro SP-250, which is a much better light.
Isn't canna coco blend of coco and stuff that isn't coco? As I recall from KingJoe using it, it drains slower than coco and he ended up tossing it and using straight coco (as he had previously).
What they say about the bricks:
CANNA COCO is washed, buffered and therefore ready for use.
Washed: Because coco palms grow near and on salt water, coco tissues contain large amounts of ions or salt. Salt can be very detrimental to plants when the occur above certain concentrations even though they generally are considered plant nutrients. In order to make coco suitable as a plant growth medium it needs to be washed. CANNA COCO is washed thoroughly with clean water so there is no need to rinse it yourself.
Buffered: Coco has what is considered a negative CEC (capacity of the substrate to retain and exchange water and nutrients).
The nutrients provided by the grower will be taken up by the medium and will not become available to the plant . This undesired effect must be prevented. In order to permanently stabilize the chemistry of the medium and its pH, CANNA has buffered its coco medium to make sure that the nutrients you give will go to the plant.
What they say about the bags:
CANNA COCO medium is a pure product with a homogeneous structure and has had a full buffering to prevent that the medium consumes the nutrients, Instead the nutrients are directly available to the plant
CANNA’s buffering process allows us to ‘pre-program’ the medium to a certain age. This ensures you get the same consistent, high quality material time after time.

All I can add is that I've used the bricks exclusively ever since I tried the cheap crap. I've never had a problem with it using the General Hydroponics' Flora Trio and supplements, or Mega Crop.
