Thank you, hoping and working to get to your level of OG grow status.
Thanks, much easier when not having to hide in the shadows.
No secret, just the soil and water doing its thing.
What I did was this.
When I decided to try out the octopots, I mixed a bail of promix hp with a 30 pound bag of EWC. Grew some NL, but it seemed to be lacking something. I used 4 times 6 gallon pots that run. Had a little more than half left over, so I added two cubic foot of Quoddy lobster compost. (Also added perlite per octopots recommendation. )
On this grow I ordered the new 12 gallon pots for the octos. I measured with a 1 gallon nursery pot and they held 16 gallons each. So I was short on soil, I added some 3rd run soil from Doc Buds high brix, which was about 25% of the mix.
When I put the seedlings in the pots, I watered with mychorr plus at the rate of of 1 teaspoon per 2 gallons of water.
Since then just plain water from the octo reservoir.
