You will have the plants so you should try cloning. Just before you switch to flower top all the plants at between the second and third joint. By the time you are done flowering you have plants ready to go.
Easy cloning
This is what I do, why I do it, and how.
What you need
Sharp small scissors I use Frisker’s and get them from Hommer depot. They last me for years but all I use them for is clowning. I clean them with an alcohol swab before using. They stay sharp and have great control. I always put the cover back on and clean them before putting them away.
16 oz. translucent beer cups, I use the translucent ones because they allow me to see if they are watered enough and the development of the root system. I use a small pocket knife to poke 2 holes one on each side. Stick the knife in a ¼ inch and give it a small twist. Holes plug slots almost never. This is for drainage.
Rooting gel, get some good stuff, if in a jam get powder. This provides the boost to get them going.
Seed starter soil; make sure it’s SEED STARTER SOIL. Buy the best you can afford. I use MG and it works great for starting them.
Get your stuff together, fill cups to the top with SEED STARTER SOIL set them in the trays and water with 6.5 ph water. If using chlorinated water put some in a pail for 2 hours. It will off gas by then. Water the cups, here is when you will see the magic of the cups being translucent. So there all wet now you cut.
You best bet is to make sure you have a node to stick in the dirt. So cut below the 3 node just above the 4 one. Clip leaves off the 3erd node and pull the clone through your thumb and finger (make a O with them) as you pull it through gently squeeze your thumb over the finger to close the O and trap the clone tips just above your finger. Now cut the tips off, stick in gel/powder and stick it in the cups as far as you can but leave the leaves above the top of the cup.
Water when you see the colour of the dirt change, the magic of the cups. Hope this helps.
I get 98% success this way. No dome just under the lights.
