Your method is impressive, the results speak for themself! You brought this to a very high level!
What would be your advice for most of us, who doesn't have a grow room, lights, and CO2, just simply want to sow couple of dozens of seeds to have healthy seedlings to play with in the following years. I am about to start something you were doing in your Zelkova broom thread, just boost the process with a simplified version of your current feeding regime. How would you treat a small batch of Zelkova and JBP seedling outdoors if you would sowing them now? And what would be the growing media at the start (jiffy or perlite), and after first transplant?
Thank you!
If using perlite...it IS hydroponic....even outdoors! It is essential to ph nutrient solution...Very easy to do.Can use drops or buy a quality meter( meters are better with cloudy nutrient solutions).ph 5.8-6.4. Keeps all nutrients available to plant.
I have used 50/50 perlite and orchid bark outdoors to good effect with just a covering of orchid spahgnum on top to conserve moisture.Water once or twice a day.
Open substrate works best. Perlit /lava/pumice or whatever else.The only organic I would use is a quality orchid bark 1/4”-3/8”. No more than 50%.
If only adding one supplement,It would be KELP.Great stuff!
Make sure you have calcium! If you can source L amino acids with L glycine and L glutamate ,calcium uptake increases by 1000’s of times.VERY good.
Fulvic Acid is also EXTREMELY good with every nutrient feed.Increases nutrient uptake and can use LESS fertilizer ,so there is more water than salt.......especially in hot weather.......Also I like less nitrogen and more supplements so all energy is not wasted on assimilating nitrogen! with large,weak and thin cell walls.Instead the plant leaves will produce stored energy through photosynthesis that strengthens plant and roots,with more and smaller and stronger cell walls...increase the Brix content(sugar in sap).
Or like you say,the SIMPLIFIED version is to AT LEAST ph your nutrient with a meter.Hydro ph is lower than soil ph.5.8-6.4 (meters are better than drops,especially in cloudy nutrients)
Also an EC meter is VERY nice,so you can see strength of nutrient solution(explanation in articles).Your water may naturally have a high EC and you end up over fertilizing.
Here are pictures and articles.Harly Smith is very informative.
