What is the lowest temperature that is safe for the plant "at night" (according to the schedule of daylight hours)? Effects?
TrollShamanstarted grow question 4 years ago
My growbox is on the balcony, at night air temperature drops to 15 ° С.
- what is the lowest temperature that is safe for the plant "at night" (according to the schedule of daylight hours)?
- what is the lowest temperature that is safe for the plant "during the day"?
Effects?

Basically a 10° drop when lights out is fine. Plants can go down to near zero without hurting the plants but it slows it's metabolizem and the plant slows in growth, takes a day to recover before she picks up her pace again. So 10° difference from lights out keeps them vigorously growing/flowering. Cheers

A 10c drop is safe in flowering, in growth stage better 5 , 7c at max

Use lights in the night so you can fight the low temps
The safety depends on the stage of the plants, in flowering with 15c you can grow, in grow plants will start to have problem especially the smaller ones

What's this mutation and how will it effect my mainlining? Should I keep the extra growth tips above my mainline topping?I discovered while mainlining my plants that a 3rd growth tip was coming from the previously cut-off nodes, but ONLY on the 2 main branches, a 3rd main branch never formed. It had 3 cotyledons when germinated but never formed a trifoil. It seems every other growth site has a 3rd.

Extra Growth Tip or Just an Extra Fan Leaf Growing Out?Extra node growing out or just an extra fan leaf? This is happening on both sides of the plant, mirrored, at every node. Anyone seen this before? Seed popped with 3 cotyledons but then grew out normally from there until it started popping (what kinda look like) extra growth tips?

Polyploid plant - weird growth or is it a male/herme?Flipped my plants into flower last week. I have a polyploid plant that I expected to grow odd flowers, but this is my 2nd grow ever and I'm starting to think it herm'd on me, or is a male despite being from feminized seeds. What do you think? Should I wait or remove it?
