(the first set of leaves you see) Carefully pack the new soil around the stem, but don't be too aggressive. Leaving room in the pot for watering is pretty much a good idea, too. :thumbsup:

Can also transplant if no room in your pots to do this. Just don't break anything when doing so. :jointsmile:

Beyond that, keep an oscillating fan on 'em. A little breeze strengthens the stems.

Before and after shots:

yeah i usually do this when planting the seed directly in soil but this time i used rockwool and i was planning on leaving a little bit of the rockwool sticking out when transplanting it to a bigger pot with soil (this is was stinkyattic recommended, prevents rootrot)...

well i guess i will try it that way anyway and just have to pray that my roots dont rot =(

thanks for the advice!
