these girls are killing it, i had to take a branch off on of the girls in the blackstar 4x4 tent. My bad hope it doesn't stress the plant, i broke during watering today...probably a good 7-10grams on it once it drys....trichomes are 50/50 right now but no amber onces...
4x4 tent with 2 blackstar500's, (560 watts total, each blackstar500 actually draws 270-280watts)

To sum it up the blackstars are 2-3 weeks ahead of the growbars. Primarily due to the heavy red ratio and that the blackstars are designed for budding. The growbars however are pulling their weight. As explained in the last post the benefit with the growbars is the coverage/efficiency. They are using 100 watts to cover a 15 sqft are with even intensity and great coverage. Traditional LED panels coverage are limited to their design dimensions most of the time. Meaning if the panel is 3x2 the coverage is 3x2 anything outside of that is supplemental lighting. That is why people should not try and replace HID lighting with LEDs, it doesn't make sense.
example: A 1000 watt light would cover a 5x5 area perfect, it would take 4 blackstar500's to cover a 5x5 and with that you are already at 1160watts total...so where is your power savings?
This model growbar I knew wasnt going to be the best for flowering but I was more interested in the coverage and how it would grow the plant. so far a success, i have 9 plants showing no signs of lack of light.These specific grow bars are designed with an even mix of 3500k and 5500k LED chips. On my next experiment I will be testing the same grow bars but with a heavier mix of red. I am working with manufacturer on mixing 2100k and 2700k into the grow bar. I believe this is the key and will be a major breakthrough in the LED game...
