First time growing. Planted one seed in a Rockwell cube and 2 sprouts came out. I figured let it ride and see if one dies. Now they are growing big and I’m worried something bad will happen. Do I need to kill one?
Don’t kill any, they will be fine. You should do some LST so that the smaller plant gets even light and grows equally as big as the taller plant.
if you can pot them up in to a bigger pot as soon as you can so their roots have plenty space else the roots will be fighting each other for space so keep them together but in a larger pot with more root space reckon they will grow ...and they should be ok ..mac,,
