Green Algae/Plant drooping

[b735170]

Anybody know the best way to get rid of algae on rockwool? Also having some plant problems that may be as a result of overwatering. I dont know, maybe someone could help. I stopped watering from 6 hours to 12 and see what happens. Any opinions greatly appreciated...

droopy leaves can often be caused by over watering.

you need to stop the light from getting to the water... light + water always creates algae.... Algae is not bad unless it gets out of control....

What I would recommend is getting some reflective material and cutting a hole in the center... then put it around the base of your plant stem... it willl stop light from getting to the water and it will give you plant added (minimal) light

You don't reflect light back to the underside of leafs. That's a bad thing; black pond liner is the best. You can even get Alga proof ones at HD by the foot.

water each time the soil gets dry...and remove all visible algea

you should not put anything black into your grow room.. the last thing you want is something absorbing light.

As far as refelecting light up, it is fine... the plants outside receive more light to their underside than any indoor garden could possibly reflect to the underside of leaves. : )

Well we disagree then is all? I know many people who use the black pond liner and have no problems. I also don't think the leaf will reflect any usable light to the underside of the leaf either. I would be afraid of the internal temperature of the leaf getting to hot. The underside of the leaf contains the stomata. The stomata open and close to regulate the flow of moisture, preventing dehydration. If the temperature gets to high for them to open then there is no Photosynthesis and that means no growth. In older plants that could lead to hermies too.

That my opinion anyway.

Zandor.... from what i have read about your incredible setup, and your lighting methods, you are probably right (and your set up is amazing)!!!!!!..

but the rest of us numb nuts only light from the top and are desperate for light in the lower regions...beyond the dense cannopies... often the cannopies will be so dense that 1000, 2000, 6000 watts of light still can not penetrate more than 4-8 inches into the foilage.... scary huh......

: ) - Maybe we don't disagree... maybe we are both right. ahhaha : )
