Can I add perlite to my soil after seedling have sprouted?

Nice move RIU removing my last post from here denying me defense.

Now how about removing all the insolent posts by others? Or are you also perlite obsessed?

Personally I love perlite. Makes flushing much quicker, and it prevents accidental over watering. Also good to have around when I don't have another cloning medium around.

I have to disagree as well, i use a mix of 50/50 perlite and vermiculite and it works really well for me, have grown compost with perlite and that allowed for good aeration, only problem is the perlite worked its way slowly to the top.

One issue is pH of peat moss is about 4.5...still looking at his idea.

Perlite less mix would require another form of soil aeration is all. Perlite isn't the only way. Many people have grown in less than optimal conditions and still get decent yield AND decent bud. No perlite in my mix.
