Day 35 form sprouting Bloom W2 D8
Clean tank and fill with new nutrient solution 2.0EC, PH 5.90
Girls show clear signs off flowering, looking healthy , stretching begin. Delay dry back time in night houres...
Still not toped this girls, this grow will be without Topping/FiM, on couple tallest girls bend main stem.
Lots of girls have flat shape, like they was topped.
For this period strong smell !
Check and recalibrate PH and EC probes. PH probe is been OFF 0.3

Last night in light period CO2 tank get empty 3 hours before light out, CO2 levels drop to 224ppm. Girls suck carbon insane. In night time it jump to 680ppm.
One wall oscillating fan died? Don't know reason why, but its 4 years old anyway...
Two tallest girls stretch more than others, two smallest girls still don't ketch up others. Not a dramatic difference , will see when stretching occurs more rapidly.
Start to gradually decries shoot size with longer dry back period between misting's.. Going slowly with this, don't know haw much is going to be needed before temporary wilting point, then i will make decision on exact timings. Temperature and humidity don't want to change for this week. Will see without CO2 , or until refiling the CO2 bottle

Activate ventilation to extract humidity and help with fresh air. Don't have intake ventilator so Co2 levels are at bare minimum 376-560ppm
Clean main room with vacuum cleaner and polish wooden floor. Tomorrow will clean flowering tent

Remove some larger fan leaves and prune some longer nodes from bottom, need to prepare net and install over plants this week..
Clean bloom tents flooring , benches and walls with h2o2+bleach
Keeping environment in tent as usual. Without CO2 nutrient strength in tank start to rise a bit (0.05)

Very nice π impressive grow room setup, noticed it's different to your previous Dwc system. Can you please tell me about it. Is it a D.I.Y system? Also I noticed the Styrofoam sheets around it, is that to help control water temperature?. All The best wishes for your grow π
