Mikromachine Auto - 3l micro grow / soil

This will be a very different grow, as my husband wanted to do his own. We only have a small tent and not enough space for two pots of decent size. Not wanting to wait 70 days for my turn, I started an experimental tiny grow (the air pot is only 3l or 0.9 gal). I wonder how far I will come. Also, manifolding for the first time, using the recommend way for autoflowers from the web page https://www.cocoforcannabis.com/how-to-manifold-cannabis-plants/ If my plant ends up being stunted from this treatment, that will be quite welcome as I have very little space. This time I am using my usual wick system with a clay drainage level, but instead of the all mix I am going for the light mix as a base, since I am going to add all the nutrients by myself. Added some pumice for drainage, as I will have to water often in this small a pot. 🤖 2nd try 🤖 My first plant nearly died because of mistakes I made. That's why I am starting anew. I soaked the second seed for 12 hours in water with some humic acid, then planted it into a root riot cube that I already put into my 3l air pot, filled with biobizz light mix and some pumice. After 4 days, the seedling started to show. I begun growing by adding only a little GBN "Living Organics" to get things started. Now that the first two leaves are visible, I will (hesitantly) start using the recommended GBN boosters. I heard great things about their "Fast Plants" spray. No N-P-K yet.
