Hey guys, I keep getting algae on the peak of my rockwool cubes. Thankfully, I alive in a place where i tin can buy clones at the shop, and within a calendar week, about a tertiary of them get a film of either dark-green or black goo on the pinnacle. The residuum are clean. I proceed the humidity at fifty%, use gh 3 part, floralicious plus, and root juice. I tried flushing them more frequently, didn't matter. Other growers say they all become it as well and it doesn't hurt the plants but those clones ever seem to exist lagging backside.

Hey!
Starting time off, It is normal for you to become algee on your rockwool, Especially when your running high humidity and your rockwool cubes are wet. What causes this is your lighting. To cure this problem, Continue the rockwool covered upwardly. I similar to use plastic tubs with lids. Place plants in a plastic tub. Take the lid to the tub and cut out 1" holes for your plants/seedlings to grow thru. By keeping the light off of your cubes algee tin can't grow. It needs some light to grow. Hope this was a help!!!

If you lot're getting algae on your rockwool cubes, they are much too wet. Go on your rockwool damp, never saturated or wet.

I would strongly advise confronting putting plants in a tub with a perforated lid, unless you're running an aero system which but mists the roots periodically. If you are running a inundation system, a lid with holes for pots volition keep the rootzones much wetter than they need to be, encouraging algae, fungus, bacteria, etc.

If you have lots of algae, information technology is much wetter than your plants' roots need. This would explain tedious growth. The algae won't be able to use up all the food and oxygen your roots need, merely the excess water will readapt the oxygen from the rockwool cubes, leading to root diseases.

Think clammy, not moisture!

I merely cut a square slice of panda plastic, and put a slit to a middle hole, and put information technology over the rockwool cube, white side upwardly. Works fer me. :blsmoke:

ane.5% h2o2 and utilise a spray bottle on a broad spread.
mix 1oz 35% into 20oz of r.o water and spry the tops of the cube. you are not looking to drench or saturate the cube just 5 or 6 spritz will piece of work it brand take a few applications but the added o2 wont hurt. please be careful when doing this because you can over do information technology and kill everything. MAKE Sure NOT TO SPRAY YOUR LEAFS!
