Update on the c99 tent:
The small 4 inch rockwool cubes are hard to water frequently enough to keep salt from building up because they dry out so fast.
I’m actually only watering with 350ppm in mid flower… 100 of that is from my tap. Run off is usually 500ppm and steady, though every week or so I still have to flush each cube with 250ml tap water and a cleansing agent.
RainDrip drippers suck. They are all so inconsistent in how much they drip.
I switched to woodpecker drippers and these are very uniform in how much they water per minute.
They are also like 3 times the size of the rain drip lol…
Both of those are .5gph drippers.
The 2 plants that are the smaller pheno are probably 2 weeks or so from finish. The larger 2 could be another 3-4 weeks, hard to say.
Good luck in your gardens
