Default grain size a factor?

hi pals, just wondering,
is substrate grain size an important factor to the well being of plants, say the tiny roots of dwarf helzine or hairgrass needs a sand substrate or will it still do well in normal grain size of 1-2mm.

welcome and advance thanks to all ur comments.

It will definitely be a factor, big or small.

Well designed grain sizes allow proper root growth and for the plants to spread well.

I like the grain sizes of ADA Aquasoil and Gex. Seachem Flourite is a little big bigger and less irregular.

Actually its OK to have smaller grains on top and the larger grains below.

The bigger grains should allow for more room for growth and the smaller grains on top help to prevent the plant from being dislodged.

Grain size does matter for the healthy development of roots, which also depends on the type of plants you're considering. Plants with massive root structure would need bigger grains to hold and develop but over the years I've tried using micro grain size aka sand with monster roots hidden beneath and the plant is healthy. Thus I've come to the assumption that so long as roots can hold onto something and there's room for development - its grows.

With that, I do have to caution you against using smaller grain. Over time the substrate would become compact and compress. This makes it harder for the root structure to develop. Get something in between bro. Follow the middle path...

thx for all e comments. i already got a substrate, green gex, but the grains are rather big, so i was wondering if my planted glosso and helzine will still take root?

It'll take root so long as u give it enough time for it to settle in.
