The black fly infestation continues! The fly traps did catch a lot of them but they are not backing down just yet. The seedlings were slightly turning yellow the last few days. Not sure if it's the soil or the black flies eating at the seedling's roots. The yellow leafs could also be a sign of too little nutrients in the soil, so I started with Alga Grow and Sugar Royal to make sure the plants have sufficient nutrients. I ordered a new bag of Plagron soil just in case. If the situation gets worse I'll just start a new grow with the proper soil. **mental note to self**: don't be a cheap-ass and buy the right soil 😜.
It´s not only about sticking-traps . You need to eliminate all the larvae , cause they are the problem . Just use some nematodes , it´ll work quickly and safe ! Good luck , Growmie
@Zengrower, welcome , buddy !! Yeah , i tried mites just once , as i found nematodes to be the terminal solution 😁💀😂😂 . And yeah , most times it´s much more than expected . The yellow stick-traps are mostly for controll of infestation and also to catch the adult gnats ( black fungus gnats / bot. Sciara analis) , but dem larvae are (imo) only really affected by nematodes (you could also use Bacillus thuringiensis israelensis , but more as prevention) . So if you have many adul gnats , there are a bunch more larvae . Also you should watch your watering , as too humid substrate will get all those gnats round you attracted 😳
Edit : those yellow stick-traps loock quite full 😌 if you calculate 1 female gnat will lay up to 200 eggs , you might get a clue of how many of the larvea are feasting on your plant´s roots (as the larvae normally eat fungi (those fungi helping your plant to live , and as there are not many of those fungi in a pot , as you can imagine , they´ll switch to roots )👻
