**Additional Update - After six days in Jiffy Pots, the root systems were all growing through the bottoms of the peat pots. I didn’t seem to have any problems with too little or too much watering, as far as I could tell.
This evening, with roots protruding from the hole at the bottom of each pot, I transplanted them into their next container. I also removed them from their peat pots, for the transplant, and noticed that a good deal of roots were circling the peat pots, as if unable to penetrate the pot itself.
The containers used for the transplant were 10 gallon Smart Pots holding a mixture of Black Gold Just Coir, along with ~30% perlite. The decision to move them directly into the 10 gallon pots was, in part, based upon a suggestion from the guy who runs the local hydro store I frequent. His reasons were that I could concentrate the water and nutrients directly around the plant itself, while leaving the larger area of coco / perlite as is, so that oxygen may remain available to the roots. As the plants grow larger, the watering will encompass more of the grow medium. This should ideally also be the last time the plants are stressed from transplanting.
Upon completion of the transplants, I gave each plant the mixture of distilled water, CalMag+, and Liqud Karma. I will also monitor the health of the plants cloely over the next couple of days, in order to see how they are coping with the move.
Additionally, I also switched the lighting over from the T5, to the platinum LED P600, running just the Veg cycle, in order to have the lighting operating at the lower wattage. The company recommended beginning this at a height of 24" to 36" from the plants. Over the next day or two, I will also closely watch the plants for signs that the lights are not too intense. I have the T5 ready on stand-by, should I notice light stress.
I am also taking photos at the beginning and ending of each day, to help me try and notice things a little better.
I’ll keep everyone updated with info as this progresses. Again, any and all suggestions are welcome. This is a new thing for me.
