Alright so the little white roots are sticking out now so I'm going to move them into my rapid rooters tray.... do they need any nutrients yet or just water? How much should I water them? The tray has these little holes next to teach little "dirt cube"... am I supposed to pour water into the holes so it goes under the cubes (there's these ridges under the cubes but I can't tell if it's for water or something or just cosmetic) Also... I've heard you're supposed to put a bag over it... I don't have a bag big enough but I DO have a clear see thru poncho lol. Will that work? I'm only growing them for a couple weeks in this before I move em.
You can use just water, or if you have some cal-mag plus around you can use a little of that. I like to use maybe .5ml of nutrients per liter of water. Just pour the water right on them. Don't worry about bags. It'll be fine.
