FAQ

Frequently Asked Questions

No, morphactins are synthetic (man-made) plant growth regulators.

They are used in research and sometimes commercially to alter plant shape, for example, to make plants bushier by inhibiting the dominant central stem.

It would be highly unusual and likely not understood unless speaking to a botanist or horticultural scientist.

Yes. Plant hormones (like auxin) are naturally produced by the plant. Morphactins are synthetic chemicals that mimic or interfere with the action of natural hormones.
