Grow Mediums When to move rock wool to dwc bucket?

HaitianPe · Sep 12, 2020

Tried searching, couldn’t find the answer on here. I have a pretty good idea on when to transfer to buckets, - When the roots are visible -, but should I transfer the rockwool when I see a couple visible roots on the bottom/sides or is one visible root enough?

100% germination , 09/02
Germinated 6 seeds in rock wool (sitting in pHd water), all 6 sprouted and are moving (I thought one was dead and started germinating another, so now I have 7 and it’s moving! lol).

5 out of the 7 have visible roots now. Pics below of ones with visible roots (I just watered them and I weigh them to water so no I am not overwatering at least I haven’t been by the looks of the girls ‍

Personally, I'd move them to the bigger rockwool cubes, the 3x3 or4x4 (they have holes for the plugs), before taking them to the bucket to let the root system mature.

Do it now.
I used Current Culture 5" net pots with a shelf but any net pot and PH balanced clay pebbles will do.

Put the starter cube on the shelf or a ~1" layer of pebbles and then fill with pebbles to even with the top of the cube. Fill the bucket to within 1/4 inch of the bottom of the net pot with 25% strength nutrients and turn on the air pump/ The bubbles breaking should wet the bottom of the cube just barely. It is hard to check so just top water the cube a few times a day until the roots are in the reservoir. then lower the water level to 1" to 1/2" below the net pot.

:goodluck:
