Hi All,

Heard a few different opinions...

...whats the general consensus?

cheers

In reference to my young plants in veg in 3in cubes i always water when lights on mate, Just my experience.

I was thinking the same thing, think I heard owd say at lights on once. people keep telling me if I water when lights on it increases chances of mould forming on the top of the cube.

ya dont water when lights are off

I read somewhere on here that generally it's better to feed at lights on as the plants are using more energy then, whereas at lights out (darkness) they are resting. However, with rockwool it's best to cover the tops of the cubes to shield them from the light and thus avoid mould and mildew etc forming.

how would I cover the cubes when there just sitting in a propagator?

Heya conflo , i would watter when you can see what you are doing mate and cover with a couple of squares of black/white if you're worried .

Hello Conflo.

You could cover them like this, cut some squares out of black bin bags as you unroll it.....Then slice up one side to just pass the middle .
I know its simple but very effective and can be done in minutes , then just slip it around the stem weigh done with clay pebz or something similar and the roots are safe from light ......cheap and cheerful my man...

appi dayz, nice one.

the white wrapper around the cubes, removed from the start right?

Heya conflo , nar leave um on mate imho , will keep the moister in for you and make the roots flow from the bottom , careful to not soak the cubes to the state of flooding um until they fully established "nft" , and i would suggest putting a cover on less of a heat conductor as black , ie use white , good luck .
edit for Bottom
