I planted 2 Bruce Banner Autoflower seeds from ILGM on 1/25/23. I started by soaking my starter cubes in plain tap water that was pHd to 6.0 for about 15 to 20 minutes to lower the natural pH of rockwool to 6.0.
Then after lightly draining the excess water I placed each seed a little less than a 1/4 inch into the rockwool. Placed those inside these tiny little Solo cups and on to an Inkbird Heatmat.
In less than 24 hours I had one seed pop already but due to the heatmat it orientated wrong and grew upside down.
So I carefully dug around the sprout and replanted it right side up.
The second seed has yet to break the surface but after some more careful digging I found her to seemingly be clinging on underground. So I'm granting her a pass and calling it germinated.
