Hi there Biofuel, Always fill the space growmie : you get product and you valorize that light and electricity bill . It's a no brainer to me. $$$$$$$$$$ 🚀
Im a newbie, but if it were me I'd replace it if its not an auto, if its auto IDK. If you do replace it, sand the seed down about 5 swipes with high grit sand paper, itll speed up the process from what i hear. Goodluck!
