OGgrowsanswered grow question 6y ago Hi mate. Give small amounts of water at a time (100ml), and let the soil dry well between waterings. If you lift the pot after watering, the substrate is very heavy; when it's almost dry, it's very light. Try to orient yourself like that. Too much wet substrate may be the reason the plant isn't growing. Try to keep the humidity at 70%-80% during the vegetative state of the plant. Only start giving growth fertilizers when the second set of true leaves grows. See if the plants tolerate the soil drying superficially between waterings. Drying between watering intervals is very effective in controlling gnats. Use yellow sticky traps to help control and monitor the problem. Sprinkle cinnamon over the surface of the pots. It has a fungicidal action and controls the fungi that feed the fungus gnat. Sprinkle diatomite (diatomaceous earth) on the surface of the vessels. The contact and ingestion of the silicon microparticles present in this material can cause dehydration and injuries in the digestive tract of insects, acting as a non-poisonous insecticide. Good luck mate!
