balansaanswered grow question 4 years ago no the seedlig need high humidty 70% and when the second true leave grows u should start to reduce humdity step by step. by end of veg it should be around 50-55% and while flowering less thn50% and at the end of flowering it should be arround 40% to prevent molds and for good trichome production. so u should manage this humidity chart with or without lid :) happy growing
