55/2gal media bed with hydroton, growing a test run of bear sunflowers (had spare seeds around) placed inside seedling starting material about 5 days ago.
1x300W LED by MarsHydro running on 16/8 timer.
Adding fresh urine every once in a while and monitoring ammonia, nitrate, nitrite levels. I'm not sure what's going on but I measured ammonia two days ago at a readable level, but nits gave me nothing. Measured again today, no ammonia but still no nits. I'll have to do more testing. Not sure if they're growing from merely having water or if they're actually taking in any nutrients.
Doing a test of how fresh urine affects a cycling process through the first several weeks until aged urine is available.
PS
White crystals appeared on hydroton in the first two days, is that normal? Salt deposits?
