Peat pellets=rockwool cubes for cloning?

Knowm,
The plastic on the pellets is not biodegradable! It just gives them a better chance as to spread the roots faster and become stable in it's new pot.Just a stress thing for me.You don't have to! Makes good practice,though!That's just what I have done in the past! I use the greenhouse flats now! 18 or 32 per tray! You don't disturb the roots and you can use them again and again! You see the roots at the bottom of the pot,through the slits for drainage.

Yeah, greenhouse flats rock.

They are easy to water without disturbing the delicate seedlings.

Just pick up the whole thing and place it in a tray of water for a minute or so.

Many seed banks recommend peat pellets for sprouting. Plain old peat will also work and much cheaper. Stay away from rockwool if possible, it sucks. Too wet.

ROCKWOOL IS THE BEST!!!!!!!!
grrrrrrrr

i used peat pellets for a while and they are great. i wouldnt use the bio.pots because they get wet and dont seem to dry and attract bugs. i use rockwool now b/c some of my plants go hydro and other soil. but those are just my thoughts

My days of using peat for anything other than a soil acidifier are over.
It holds too much water. It has a pH in the 4 range!!!!!
Wet+acidic=sad plants.

I suspect the pellets are treated to be pH neutral.

I've moved on to a mix of 1 part vermiculite, 1 part perlite, and 2 parts seaweed compost.

Both peat and rockwool hold a lot of moisture. Peat for soil and rockwool for hydro, mostly. This has been nothing but a problem for me and I highly recommend something closer to stinky's recipe, at least for beginners. Perlite is great at creating aeration, and vermiculite is great for holding moisture (both are essential). Experiment with mixes to see what you like.
