hey guys my hydro plants arnt doing so good.... they took of fast now have slowed and i noticed some green stuff growing on the rockwool cubes its slimey like alage.
Bro, it is algea, it grows on rockwool unless you cover it up with something, but don't worry about it it's quite harmless.. And about your plant growth.. How much are you feeding it and what is the ph at?
Did ya clean those lava rocks good? If not they may be messin with your PH bad enough to cause some nutes to lock up.How long has that cube been in there?
alge for sure, either cover it or keep good air movement over the rockwool to help keep it dry, wet + light = alge
Green=Good Black=Bad Its going to happen when lights are on any water substance/surface for a long amount of time. You can cover it up but I don't stress it, long as it stays green.
well i havent started feeding the plants yet because i am still not sure on what nutes i should use. ther isnt a hydro store around me so i dont know what to do? thanks for the fast replys guys. ph is 6.4
ph should be 5.5-5.8....and a cheap way to stop that algae problem, just wrap the top of the cube/container in foil...good luck 2 u!
allright thanks for the help guys so i guess i will be buying some ph down than to get the level right and covering the rockwool
