I have found that the gel one are highly price compare to the powdered one. I had better result with gel one, never killed a tree for having too much, like I do with powder. Other advantage of Gel or liquid, is uniform application compare to powder. Liquid as another advantage, you can dip it, and let it sit a few minutes to make sure, the liquid fully infiltrate the stem. If you leav it dip long, you should use a milder solution.
On young seedling, if you go with powder, make sure you dont put too much. I would suggest a milder IBA (the active ingrdient)
To give you a short summary :
0.1% IBA is normally for softwood. Flowers, Geraniums etc....
0.4% IBA is Semi-Hardwood... Easy rooting tree
0.8% IBA for Hardwood tree and conifer
For a seedling , I would suggest something in the range of 0.4% since 0.8% will be to strong, and you hare not doing a cutting of wood but rather weak flesh.
The highest I have seen is 1.6% IBA, and rumors says that you can have some 2.0% IBA but never seen it it. The higher rated ones, are only available in liquid and in bulk quantities.
