I have some on the tops of my 6" cubes and some on my grow mats (not severe but still there). Most of my plants look good but a few look kind of wilty and weak. Anyone out there with the same problem and any idea on how to deal with it? Also for next time how can I prevent it from starting in the first place? If this is addressed somewhere else I'm sorry but I looked around the site first and couldn't find any conclusive info. Thanks!:thumbsup:
Algae and rockwool go hand in hand.
It needs light to grow, so preventing light from hitting the surface is a good start.
Usually it is simply cosmetic, but yes, if it gets out of hand to the point where it starts to rot, you have a problem.
I'm not a hydro nut but there are other threads about fixing this in the hydro section.
Brite Ideas Hydroponics and Organics :: Hydro Kit Accessories :: Pots & Net Cups :: American Agritech Root Guards 2"-6"
These help stop light from hitting your rock wool. laterz..

only thing Algae does thats really bad is algae and the planet ends up competing for oxygen so aslong as the roots have air it should be fine so if it's in the res and closed with no oxygen then the roots have less air and there for can lead to starving the plant of oxygen thats why dwc is good cause not only does the plant get the nutes but constant air being pumped in as well so on top of rocwool not so bad
Algae uses air as do plants
Algae & Rockwool - How do you deal with it?
By not using rockwool.
Seriously though, don't worry about it. I don't think you can stop it, unless you keep the light from it.
Please consider using clay pellets. Way better than rockwool in my humble opinion. Much easier to work with, completly reusable, doesn't hold vast quantities of moisture as rockwool does.
I noticed that too while using 1" and transplanting to 4". Then I went Hydroton for finishing. Thinking about just the 1" then into Hydroton pots. Should battle the algae a little better.

Why all the transplanting? When the clones have about 3 inches of good, furry roots, put them in a 5 or 6 inch net pot with a 1 inch strip of capilary matting (it's just kinda like a wick) touching the roots and the bottom of the pot. Gently fill in clay pellets around the plant.Quote:

When I want a plant to grow in soil for the duration, I put clones with about 3 inch roots directly into the soil, and that's it. No transplanting.
I like to start with clones, even if I'm using soil. It's been my experience that it's much easier to get a good healthy root mass by starting a plant with scarification (search it), and a bubble cloner. And of course that way I already know she's a lady.
