i have done a search but cannot find any threads on hand watering in rockwool. it would only be for the veg stage, or does anyone recomend another way to veg hand watering in soiless method??

my 10 pot wilma with pebbles or rockwool will be used for the flowering as i want to move away from soil and coco(too messy).

please give any help you can as im a bit lost as what to do.

cheers jon

Fill a dish with a lil of the water that you have already prepared put the blocks in there until they have soaked up water. Basically water from the bottom cos algae will quickly grow if water is sitting on the top.Hope this helps.

hi mate, im trying this for the first time too.

What i've done is rooted clones into 1" rockwool cubes, and when they have rooted i have put them into a small pot with clay pebbles. As this is my very first time with hydro im not too sure what im doing but i have managed to keep 6 out of 18 cuts fairly healthy, the rest i mangled up by fogetting to water and not potting up soon enough
They deffo need to be watered every day, as clay pebbles dont hold much moisture at all.
Im using canna aqua vega nutes at 1/2 strength, ph'd to 5.6 and bubbled for 5-10 mins before watering.
Eventually i will put them into a bubbler.
Still though, its all a learning curve, most of my first clones in soil died, but i got 100% success on my last attempt!

Im thinking about transferring some into perlite and some into vermiculite to see if there is any diference

Hiya Jjon,

just thoroughly soak your rockwool blocks then squeeze gently to remove about 10% of the water.
As to frequency of feeding,which will increase with time,just pick up each block and weigh in the hand.
You will soon develop a feel for estimating how wet or dry your blocks are.

Only word of caution is for you not to sit the blocks in a tray without drainage.If they sit in a puddle the plants can quickly drown.

dead right mate, its a learning curve.

i want to hand water them as my clone/veg area is on 2 shelves and res is in another area. i want the clones to be ready for going straight into my system and on 12/12 after current flowering plants have been chopped.

so i can get the crop time down as i have been putting plants into system and then waiting 2/3 weeks before going 12/12. makes the whole cycle seem endless.

cheers jon

Hi i put the 3" cubes in a tray with an inch of water, in the tray i lay soaker hose i run it thru the groove in the cubes to keep it submerged connect the hose to air pump, ive kept cubes for almost a month like this with good results

Pot the blocks up into pots with pebbles and water them once a day with quarter strength nutes

If while you are waiting they fill them pots up rootwise then pot up again into slightly bigger pots.If you have the room then you can put em into their final pot size

interesting,,,cheers people for comments and help.
