    Re: Confused about flow

    Hi, I made a few changes before anything major.
    I've taken the screen out of the slot and pointed the slot at the screen, although my flow clearly isn't up to spec the water does reach the full length of the slot so the entire screen is getting flow.
    The only lacking in flow is where my screen clips are blocking the slot as you can see from the streaks.
    I also removed the blue leds as they were clearly pointless since I couldn't get then in the right position to amount to much.

    Here are my 7 day growth pics:
    I haven't cleaned yet as I may leave another 2 days what do you think?

    Re: Confused about flow

    As I can't make any major changes yet (due to materials and holidays) I have increased flow in the mean time by removing the end lengths of screen and joining the 2 pipe ends together.
    This has reduced screen length down to 2x 10 inch single sided but increased flow to 9.5 gallons (US) per hour per inch. I know this is still low by SM standards but the screen is not in the slot and the flow over the screen looks strong and consistent all the way across.
    I've also stuffed the third bulb into spaghetti jar number 1 increasing intensity on the remaining screens, so I have a total of 69W.

    Another 10 days will be interesting to compare...

    Bit hard to see but you should get the idea:
