Chilies 2020: Plan B

2020-04-13 08.32.20My original plan was to move into full hydroponic gardening setup in our greenhouse early this year. However, during the Easter weekend, we got again a “takatalvi” (a cold spell with snowfall) in Tampere, and the greenhouse will stay closed for a long time, still. Thus, a Plan B.

I had both twelve chili saplings of different varieties, and twelve small “self-watering” plant pots – these are Orthex Eden 12 cm models, meaning that they have only 0.3 L water reservoir, and 0.8 L for the hydroponic substrate (or soil). I had also a 45 L bag of Gold Label HydroCoco 60/40 substrate in my stash, so I proceeded to make a “passive hydroponics” setup using what I got. I washed the pots (they had spent the winter outdoors), then buried the rockwool cubes (with saplings sticking out) into the substrate in each self-watering pot. The nutritient mix is again based on Canna Coco A+B.

I multi-purposed a Bosch workbench from our garage as the growing table, and positioned the Nelson Garden LED growing lights hanging close above the plants.

2020-04-13 09.51.07This system should make do for some time now. The only downside is that small water reservoir in all of those 12 pots. I have no idea how fast the small saplings will drink that amount, so it might be that soon I will be mixing nutritients and filling in 12 pots every day or so. Let’ see: the maximum amount of liquid these pots can take is under 12 L, so if I will prepare a large 10 L bucket of the nutritient solution per each “serving”, this should be pretty straightforward. Canna, the nutritient manufacturer, instructs to use 19 ml of A solution and 19 ml of B solution per 10 L of water in the starting & rooting phase, and then add the dosage into 23 ml + 23 ml, when the plants have entered the early vegetative, growth phase. When we’ll have a bit larger plants (2-4 weeks-old saplings), the recommended nutritient amounts are 27 ml + 27 ml, per 10 L water.

Let’s hope for warm weathers to return, too!
