Thanks Perception and Minitiger
Perception, no I think I built the final container around week 6 of veg and went the full 8 weeks veg. It was time for it's second transplant. This made it difficult to figure out which ones were female/male as not all of them were showing sex and I didn't want to waste soil, or time, or softpots, or space in the tent. I only had so much soil ready to go. I did ultimately build containers for some males that I pulled only a couple weeks later. Both batches of his soil I have made, I multiplied all his amounts by 1.5 because that would start with 1 full bag of
ffof (1.5 cu.ft.). However I did start my container building with a possible male just in case I made mistakes which I did. There were a couple "oh shit, I forgot the top layer, or the mycorrhizae" moments but, by the end, I had it down- and I was running out of soil quick.
Also, don't use any Manure in his soil mix or his layers. He has them listed in his recipes but later on in the book he says he no longer uses them because of fungus gnats. Luckily for me, I couldn't find any for my first batch because everywhere I went they said it was still frozen outside -then afterwards I saw where he says he no longer uses it (imo, he should have fixed this in his recipes but I ain't bitchin ). I used his soil straight for the first two container sizes and put a little mulch on top only.
Yes, you want to add the spikes near the outside of the container during transplant so you don't stab the freshly transplanted roots.
