@Tn420, don't use it on young plants grown from seeds. The fungi will come looking for you; it's too risky, especially the ones from the soil.
Use a humidity dome for the cuttings.
Their humidity is around 40-50%, while ours is 70-80%, more than enough.
During this rainy season, I was rooting cuttings, and the ones under the dome all rotted, but the excess plants outside the dome somehow survived.
If you're going to cover them, you need to open it to let the air out two or three times a day. Don't let water droplets accumulate. In summary, just don't do it.
Your Fruit Cake Auto is developing beautifully! The leaf structure looks very healthy and the plant appears to be thriving. Keep up the excellent work with your grow!
