    too much darkness?

    just the opposite for us, 3 weeks into veg the power went out for 4 hours while the lights were on for there 18 hours, hope it doesn't hurt our girls and make them boys when they make the transition.still have 3 weeks before they go to 12 hours. jr

    General Hydroponics Feeding chart

    I agree the chart does seem to high for us too, use less and watch your plants leaves, we only raise the nutes once a week or every ten days. we use half of what it says to use.
