it retains some i use 100% Perlite for my grows....... The more fine, the more water it will absorb. The tiny pores in perlite hold bubbles of water and oxygen.

The advantages of 100% perlite or perlite/peat moss growing mixes are not limited to weight savings only. Horticultural perlite is an inorganic mineral of volcanic origin. Thus, it does not rot or otherwise deteriorate but continues to function in the growing mix. In addition, because of its unique surface configuration, particles of horticultural perlite will retain from three to four times their weight in water on the surface yet they will not become soggy. This is an important consideration with container plantings as this type of planting tends to dry our faster than plantings in the ground. This feature of perlite will produce healthier plants and trees while requiring far less attention (and less water.)

Perlite is a big part of my base, along with coir. I read this quote some time ago and it stuck with me. I have other amendments, but these are the two main ones. I also have a touch of vermiculite. (Don't worry, it's not catchy) Of course I meant in my mix. I have been recycling this mix for over a year now. You can see it in action above. I do plan to split it up and add fresh coir and perlite to each, essentially doubling up, which it seems I need to do. Flowa, you really got that scrog thing down man, that girl you have is a picture of health. Wish you could share some with me.Unlike peat moss and bark composts, Coconut Coir did not break down or compact. Containers that had been filled with Coir four years previous were found to be at the same level and consistency. http://vgrove.com/coir.html
