All the bulbs have sprouted and the roots are growing healthy.

This is indeed a problematic batch. All the bulbs kind of rotted or grown soft and some harboring tiny larva worms. Only one final bulb still surviving.

Lesson: if there is a strong pungent smell and the roots are no longer growing, it is a sign the bulb is not doing well.

Spray some Enzyme to counter black mold.

Addition of some hanging pot and deck tile on the big water container.

Seems to be doing well (at least no side effects) after 1 week in the diluted humus fertilizer.

After 80 days, I believe this plant has grown beyond its peak.

Leaves look healthy with roots growing. Experiment with feeding it humus fertilizer diluted in water.

Mix 2ml of neem oil with one teaspoon of concentrated dish soap (select plant or environmental friendly version) into 500ml of water.

0.02g (one scoop of the tiny spoon provided) per litre of water.

Water the plant with this solution to kill the gnats in the soil within 24 hours. The solution is effective for 14 days.

Pour Mosquito BTI solution into the soil to kill the baby and larva gnats within 24 hours. Mix 0.02g of Mosquito BTI per litre of water.
