working solution

pic 1 is about a 5 day old solution, just shaken.
pic 2 is the same solution 10 minutes later. almost the same amount of bubbles.
this solution will last about 7-10 days. the amount of co2 produced is unknown.
I am in no way suggesting to pee, put urine on foliage or in the soil, or to have this solution touching the plant or soil. if that happens, its on you, not me.
I am using a portable kerosene heater for supplemental heating in the grow room, it's unusually cold for october. its the norm for heating where I live (no central heating/air for most housing). burning kerosene also produces co2. damn fire trucks drive by at all hours reminding ppl to ventilate their houses/sleeping areas during winter, as the majority of us sleep on the floor or at floor level and co2 it toxic to humans in large quantities, on a loud speaker!
co2 is heavier than many compounds in the air, the carbon molecule makes it so, it sinks.
also, plants don't use co2 when its dark, some may stick to the foliage, but don't bother shaking the solution in the night cycle. in fact, stay outta the grow room when its dark! any co2 will collect at floor level and be used during daylight hrs.
a fan is very important for this reason. the co2 needs to be up where the leaves are, its wasted on the floor. my fan is only on 15 min every hour, but I go in there at least 10x a day. ventilation is also important, or some type of air exchange, even if you're using a fan for circulation.
so, pic 3 is of the grow room with the heater and fan shown. any heat source should not be directed onto the plants, they will wither and possibly die. I'm only experimenting with the kerosene heater at present. its directed away from the plants, towards the fan, which is also not directed at the plants but at a wall where the wind will dissipate. as I am using cfls, very little heat is produced and this seems to be a very cold winter for me, I use a small electric ceramic heater to maintain heat, @30 degrees Celsius. humidity remains around 40%. also, by placing a tea pot on the kerosene heater, steam is produced, ie; humidity increase.
if you look at my album you'll see some bottles of this solution amongst my crop. if you try this let me know what you think and if you get good results show some pics. I'm happy with what I see in my plants.
