I'm in a mix with coco plus some organic soil mix and perlite - what I had here to start them in April. I pre- cal-mag watered the soil a day before planting, watered every 3 or 4 days as needed in 3 gal. The past 4 waterings I've done bottom up with NL Chewy while watering Lemon auto's remains from the top, to save time. I rough up the top soil and spread it to the sides were it gaps when they dry, before I water. I start in the middle then next pour I get the sides. If water came out sides too early I just leveled the bag out on the saucer but make sure bags are wet all around. They sit on wire shelves. I'm liking the bottom up watering thing. I use cal-mag, GH Trio, Flower Fuel, molasses, Recharge - whatever seems best that day.
