Hey guys, our plants are in week 4, they are doing great, the only problem now is small flies that are living in the soil. We tried to get rid of them by using stickers and also green soap spray. It helps to reduce the number of flies but doesn't help to get rid of them entirely. Any suggestions on how to do that? Also, maybe you have any advices on upgrading our growing conditions for further growth stages? We have 3 t5's, a fan blowing 24/7. we are growing the plants in the soil. Always keeping the temperature of the room above 70 Fahrenheits. on week 3 they received their first nutrient feeding, planning to do the same on week 5.
