Burmeseanswered grow question 4 years ago Hi there, First of all, Don’t underestimate the growth of root.Even the small seedling have alot of roots growth down there.I think it’s the best time for you to transplant.Later on, the roots will mess with your plant’s growth.I always recommend to transplant when leaves become parallel with your pot’s rim.Always take caution while transplanting and don’t expose your roots too long at outside.Prepare your final pot first.I recommend to use at least 5gallon pot as final pot.Turning your plants upside down and cover your pot’s opening side with your hand.Gently remove your small pot and put your plant inside your final pot.Water about 50~100ml as soon as possible after transplanting.Happy growing... ✌️
