Im starting some new strawberry couch seedlings and i have a question about rock wool cubes.
What i want to know is when you plant a seed in a cube and its ready for transplanting, does the roots grow SIDEWAYS or just thro the bottom?
I didn’t get cubes what i did i got small yogurt pots. And i intend to use em as rock wool cubes. I already got 3 seeds planted. What im gonna do is cut off the bottom of the pot with sharp knife and then plant the plastic yogurt pots into proper pots when they ready. under MY calculations it will utilize 80% of energy for root development.
However, if some good rockwool cubes also grow sideways after transplanting i can got further and carefully first cut of the bottom and then cut a line from top to bottom of the cube, The expose the entire mass and carefully transplant it.
Soak the cube in PH 5.5 water, shake it a bit so it’s wet, not soaked (not dripping freely), put the seed in the hole, press it down just a touch with a toothpick/chopstick/narrow tool of some sort, place a small chunk of roclwool into the hole (loosely. To keep out light) and let it sit.
I prefer seedling starter bags. Just fill with your medium of choice and when ready, plant whole bag in new pot. Not Rockwool but it works well for me.
