Transplanting from Hempy/Perlite solo cup into Soil
Starting off with PWF #1 pictured here next to the solo cup with soil into which she will be transplanted. It's important that the soil be dry when doing this. It makes it so much easier and gentler for the seedling as you'll see.
So to gently remove the seedling from the perlite/hempy solo cup you do a step called floating the perlite. Notice in these photos that the perlite is about 1-2" below the top of the solo cup. This allows me to add water to the cup until the perlite is literally floating in the water.
Step #1 is to cover the hole with some type of tape that will prevent the water from leaking out of the hole. I use regular old duct tape for this. Here you see the duct tape covering the hole. Next step is to add water until the perlite is floating.
Here you can see that the level of the perlite on the inside of the cup is quite a bit higher. This is because I've added water and it is floating in the cup.
Next is where you want to be very patient and gentle. Also, I sanitize my hands well when I start this step. This is where we remove the seedling from the perlite. What I do is squeeze the plastic cup moving the perlite inside. I turn it a 1/4 turn and squeeze it gently again. All the while I am VERY GENTLY pulling up on the plant's stem. If it's not moving I keep spinning and squishing the perlite. Eventually (or at least every time I've done it) the seedling will start to come out for you. Here is seedling #1 at sprout +3 days out of the perlite and ready to go into her soil solo cup.
I do not worry the least little bit about the small pieces of perlite the roots have grabbed on to. I plant her just like you see her.
Next step is making the hole in the soil to accommodate the seedling. I use the handle of an artist's paintbrush to make the hole. I make it precisely as deep as I want/need it to be by holding the brush against the stem and root to measure. I then make the hole wider then the root mass so it slips into the hole unfettered. Remember we're trying to be as gentle as possible. Once the seedling has been placed into her hole, without letting go of the stem I use the paintbrush to push soil against the sides of the roots. Just enough to hold her upright and then I'll use both hands. I go around the seedling pushing the paintbrush nearly to the bottom about 2 inches outside of the plant. I then gently push the soil inward towards the center of the cup/seedling trying to gently pack the soil into contact with the taproot. I go all around the cup doing this making probably about 8 holes total. Here are a couple pictures that hopefully will give you a good idea of what I mean.
I then use my fingers to gently even out the soil and work it till the seedling is standing nice and straight. The last step is watering the seedlings. The ultimate goal is to create an abundance of healthy roots which will help your plant flourish. This is part of the method I've learned from Emilya.
Right now the seedlings have basically their main taproot going straight down. You can see in the photos that they have started putting out small side roots. These are what we want to encourage to grow. Here is the photo of PWF #2 showing her taproot and start of her side roots.
Compare her roots to those on PWF #1 who is only 1 day ahead of her above ground. They move quick, much quicker then I used to realize. But you can see here on seedling #2 the beginnings of side roots. To encourage the plant to put out more lateral roots I've learned to water towards the edge of the solo cup. The plant will send out lateral roots because she can "smell" that water and needs it to survive. So she will send roots to the sides of the cup to capture the water. Here you can see how I'm watering around the edge of the cup.
I also like to use a clear solo cup inside a colored solo cup with seedlings and clones. This allows me to monitor the health of the root system. It also helps me to know when she is ready to be up-potted. In this case you can see the moisture which has run down along the inside of the clear cup. The plant is already sending out lateral roots to get to this water.
I DO pour a very small amount of water down the center with the initial wetting of the soil. I do that for two reasons. First, I want the water to help remove any potential air pockets and move the soil into contact with the roots. Second, I want to be sure the plant has some moisture. I pour a very minimum amount down the center, just enough to get things going.
And that's pretty much it for now. Both girls I feel were successfully transplanted with a bare minimum of trauma. I expect both of them to flourish from here out. Here are a couple photos of them in their new homes.
