Exactly and yes. I have noticed that during my first batches of soil I will need to amend with fish hydrolysate and spray with calcium to get the plants through a grow. The second round I don't have to add the extra N any longer. I am still struggling with calcium issues but I believe that is from the high amounts of phosphates that I use coupled with calcium not being very mobile. But I have definitely seen an improvement in plant growth from first run to second while adding less amendments to the soil. I was constantly adding teas on my first batch, this last batch was straight water from start to finish.
Awesome! To use just rainwater from start to finish is killer and my end goal. Now once that is down, if I can only time my watering to the weather pattern here, so I get just fallen rainwater into my tent-haha, well, awesome lol. I even had a crazy idea that I could somehow rig up my drainpipes to my tent and have some kind of sprinkler/drip system that fed the fresh water to the plants....kind of crazy, but certainly not impossible lol.
Dazed.
