hey B/L no crispi credit due here ,
i pirated the idea from someone else on here . don't remember who now ? many many dubes ago . lol . :jointsmile:

i tried the intela drive track n just 1-1000w. light -n- it just took way too long to flower . thingz went way way faster n budz were far denser w/ the 2 -1000w. hps. being stationary .

the valves are your friend B/L . not just for checking p/h -n- ppm , but for my ease of draining the sys. , and when we mix nutes . we can leave valves closed and fill res. w/ water -n- mix nutes right in the resovior -n- just open valves to refill the sys.

peace
your cuz
