Same developer, FX-2, but at half strength. I generally agitate for the first minute, then leave it alone.
The first time I tried this I had just two 9x12cm sheets to develop, so I decided to put them in an old "Johnson Cutplate Developing Tank". Inversion is impossible, indeed agitation of any kind is as good as impossible. So I gave a five-minute presoak, poured out the water, poured in developer, then went off to watch TV for a while. Poured out developer after about 90 minutes, then quick water wask and fix. Negatives were exellent!
