It is roughly 7 days since these seedlings have been placed under T5 lights. The 3 untreated seedlings on the left continue to look nice to me. I can see 2 major differences with the 3 gibberellic acid treated seedlings on the right. They continue to be leggy despite keeping the lights only a couple of inches away (with fan running). Development of the first leaves is slower in the treated group. The untreated group has emerging 2nd leaves where the treated group only smaller 1st leaves. Eddy Z has commented that in his experience this type of behavior is consistent with seed treatment with GA that is too concentrated. I used a 0.1% gibberellic acid soak (1000PPM). So I assume that anyone who intends to use gibberellic acid to try and germinate some old seeds needs to be well below this concentration.
