ouch, i have no root control disks for this grow. I notice the coco comes out of the bottom of the pots a little...should I get some ladies nylons or something to put around the bases of the pots? Im afraid when watering the coco will come out and clog lines or cause a mess? I would use landscape fabric, but massachusetts/december/finding landscape fabric dont mix!
I just went through the same dillima. The root control disks have a copper layer on one side, it is supposed to control the root growth. Is this really necessary?!?! Can you just use any ol' piece of garden barrier instead? The copper coating seems to be a proprietary thing that autopot does, I've not been able to source similar weed barrier anywhere. A roll of weed fabric costs about the same as four root control disks and you could cut out probably 1000 squares from the roll of fabric.
Seems like you would get too much contamination in the tray to skip them altogether, but I know one grower who just that, @Corgy, but he was using the bigger autopots. I'd love to hear what some of the other experienced autopot growers are doing for root control fabric.
