Which device for ppfd?Not directly a grow question, but:
Which device are you guys using and/or recommending for measuring ppfd? I’m on a TIGHT budget and it needs to be shippable to Germany or at least Europe. I don’t really know anything about ppfd.
Pic is just for visibility.

Should I harvest my plants?They are on flowering week 9 (calculated from when they started actually growing pistils, not light period switch). These plants are unusually tricky to interpret, there's large differences even in same bud. They also keep on pushing new bud growth despite optimal conditions.

Day 58 flowering, I have limited time left, should I switch lights to 13/11 or 14/10?DWC, 2 plants, both sativa-leaning: Baikal Express by Kalashnikov seeds (right one in the group photo, 1st closeup) and unknown bagseed (2nd closeup). It is day 58 of flowering today. I need to vacate this space on day 70. Should I switch lights to 13/11 or 14/10?

Fridge stored seeds not poppingI germinated seeds that I stored for 1 year in my fridge. I'm wondering cause RH and Temp is ideal.
so far 1 popped out of 4, total 6 but 2 I added later
I added my greenhouse later - maybe top layer dried too fast?
Germination date: 06.09.2026 - see diary… Show more

Should I start with flowering fertilizers? Is this autoflower already flowering? I am not sure because they are kinda smallAre they already flowering, and is it the right time to introduce flowering fertilizers? I have been giving them supplements and nitrogen. They were planted late June from seed. It is my first grow so I am not sure. I have never seen cannabis plants. Thank you for all help 😀

How do you protect your guerrilla grows from wild animals and predators?Lost an entire guerrilla plant to animals. It was pulled out of the ground and another one had the stem base eaten.
Hunters recommended Hukinol, but I can’t get it for 5–10 days.
