<span class="link_user">@AsNoriu</span>, niiice! I will try with 72 hours, but i will keep watering them during this night period, properly flushing the roots. I have a green headlight, which is perfect to do things inside the tent without "waking" the ladies :D Thanks again for your advice
<span class="link_user">@Ninja31</span>, i read a lot about darkness shock. There is one really good article or research work about it from holland scientist. Short version of it. Plant needs at least 72 hours ( 3 days ) for results to be expressed in real trichoms increase.
In shorter time plant reacts, starts to defend himself, but for that to become reality plant needs time, 3 nights. Research showed aswell that there is no bigger increase up to 5 nights, but cuttoff minimum is 3.
Water them well before darkness, give 3-4 nights and enjoy frostiest weed ever ;)
