Day 6.
Well, so much for my LITFA application.
Calculation of my pool shock concentration in dilute and final application.
60% calcium hypochlorite powder
5ml is 11750mg*0,6=7050mg(actual chlorine)
mixed into 1000ml water , 7.05mg/ml
20ml to 20l(4.4gal) = 7.05mg/l
10ml =3.52mg/l
5ml =1.76mg/l
2.5ml =0,88mg/l
After a res change with tap water and adding 2.5ml of this solution, ORP is approx 570.
Will need some free and total chlorine test strips to keep on top of this fully. Especially later on when root mass and organic load is larger.
jijiandfarmgang on rollitup has been running +600mV, making me suspect that neutralizing chlorine with vitamin C is not needed.
Manicbotanix recommends to maintain 780mV with ~0.5ppm free chlorine, applied every 2 days.
0.88mg/l from the 2.5ml of concentrate solution in addition to tap waters 0.5-1ppm should be a perfectly safe ~1.5ppm.
Moved the runt who dropped out of her seed pod to a covered perlite pot on my speaker, it is behaving like a cutting, starting to root from the tap root, it cant keep up with the rest so it gets the sidelines.
Maybe it will be perfect for becoming a CS dad should it live.
My trusty 20yo MaxiJet 1000 pump finally took it upon itself to die, temps now 21-22C since chiller cant be used used, new pump ordered.
Airstones had moved while fault finding the pump, 3h without direct splash wasnt a good thing to the little ones, can see it on the pic, they are going again tho, new growth at the end.
