seedlings growing too close to each other
I have some Trichocereus seedlings but some are growing so close to each other that they're almost touching. They just got their first spines, and I was wondering should I leave them or try to seperate them? They are also a bit etiolated, but after I put them under a CFL light, they continued growing normally. Will that etiolation make a problem in the future?
Any help will be apprecited.
I didn't find the right solution from the Internet.
