I'm about to start my first grow, and will attempt an organic 'living' soil in an outdoor SIP system*. I have no idea if I will need to feed after planting. If so, how? Can I top dress if I'm not top watering? Drain the reservoir, top feed, then flush it out after? Foliar feed?
If this is the wrong sub, please point me in the right direction. And, of course, thank you in advance for any advice.
*I'm planning on a noobwannaB style SIP system
. Each 25 gallon cloth pot will sit atop a layer of lava or perlite contained in half of a 55 gallon drum.
