Corgy, I like it! Get the sheapest garden store soil you can find! Douse it with mosquito dunks though first...lol! I did something similar with a thread I called Little Orphan Cheesy. I used a bag of $0.99 soil that looked like ground up pavement and got just as hard...lol! Nutes was cast off res water from my DWC grow..............when ever I happened to remember! And the plant turned out nicely even with all of that! So please, put a hurt on a couple of those girls Muuuu ahhhhh ahahahahahaha!
Done deal.......man, these Autopot set-up's, can't wait to not having to lug a 10 L water can around and maneuvering it around a densely packed jungle.......the plants have gotten way bigger and bushier than I would ever have thought on my first grow. One TD is past 130 cm at day 59 and still adding 2-3 cm/day.........will supercrop or top the witch soon if she don't slow down.......really missing those 220 cm high tents.....oh well!
