The old plushberry seed taprooted. Took 3.5 days. Couple days more than my fresher seeds take but the heat mat and controller seems to have been a good purchase.
If anyone is interested here is my seedling process.
Everything cleaned with isopropyl alcohol. Seedling in moist coffee filter in a dark container in open baggie til tap rooted. Heat mat set at 80 degrees farenheight.
Watered in to good runoff so there is some space at top of cup. This is Mothers Earth Groundswell potting soil. Similar to ocean forest.
Make hole with unsharpened pencil about a centimeter deep.
Carefully take tweezers and plant taprooted seed root up in the pencil hole. Cover over and pat down soil gently.
I use plant label stakes. I indicate the name of the strain/ cross and the number. Sometimes there are more than one so the numbers only go with what is in the garden. I dont label the 40th BLT number 40. If she is the only one she is called #1
On the back i label the sprout date and the transplant dates and when they went i to 12/12. Can always tell how long they have been in their pots at a glance.
I cover with a little diy dome but only to keep soil moist while sprouting and to protect the little thing from the wind. It comes off when i see green. Seedlings dont need high humidity. Thats for clones.
Clean and dried off tray.
And she joins the party. :)
Here are the 4 Toxic Blue lower branches i took. Water cloning is easy but slow.
Veg gets well water only as they transplant up to the final pot. I never adjust ph and translanting gives fresh nutrients from the new soil. Average 6 weeks to go to flower. Most plants show pre- flowers before going in.
