@Yhanus, hello and thanks a lot! I will gladly help as much as I can. No, I am not using a chiller, the room of the tent stays at ~18°C and the tent itself is heated with a temperature controlled fan heater to the desired temps. Since only the air is heated, it warms up the plant without radiating heat, so that the bucket etc stay cool.

@einamio, thanks a lot! I really appreciate that. I like to use Silicate to give some more trace elements from the natural ground. However, i just started using it about 2 grows ago, so I can't give perfect advice. I personally use just little amounts of it, about 0,1-0,2 ml/L and stirr really well before refilling the reservoir with the prepared mixture. The Silicate only dissolves in tiniest amounts, so giving more will just end up clogging the air stones. The water is always a bit cloudy with it, so I am pretty sure it doesn't go to waste. Hope I could help and happy growing! :seedling:
