So I was hoping to move these guys outside soon in...

Fibro_Witchstarted grow question 7 years ago

So I was hoping to move these guys outside soon into 5 gallon pots in my garden. I know marijuana can be pretty hardy, but I was looking at the extended forecast and it's still dipping down into the mid-high 40's F at night. What temp range can I safely move them outside?

Hi there! Strong genetics can handle cold temperatures, as low as 50°F (10°C). Anything below will hurt the plant's tissues. However, 50°F is still under the optimal range, and may result in slow growth and bad photosynthesis, so you probably should wait another week or more depending on your local forecast. I'll be around, keep us up-to-date and good luck!

I've just gone through very low media temperatures, and plants don't like low temps I've found. Air temp is one thing, but don't forget media temp. If the media/pot is not warm/hot, they'll stop growing or even go into reverse (leaves get smaller as they tighten up with the cold). Unless you have to for space reasons, I'd keep them somewhere warm until it's warm/hot enough outside. Perhaps even use the sun during the day and bring them in at night when it's too cold. Media temp must be >20c for decent growth to continue in my experience. Really young plants love ~28c.

Anything below 14 Degrees C can kill your plants. Unless they are strains bred for the colder climate. You can always put them out in the day and bring them inside overnight, until you get steady night temps of around 14 Degrees C or above.

Trimming My plant is dense, all of the stems and flowers are close to the stalk. I was wondering if trimming all of the sun leaves to make room for sunlight would be a good idea, I don’t want to hurt my plant.

Cut off leaves for better bud development?I saw some diaries where plants have nearly no leaves and produce a nice amount of good looking buds. Is it recommended to cut of most of the leaves at the end of flowering, that the energie goes into bud development?

Pre-flower defoiliation I flipped my lights to 12/12 about 4 days ago and I don't believe I done a well enough job on defoiliating. The plants are healthy but the canopy looks a little crowded. Can I defoiliate now or should I wait until the pre flower stretch is finish

Trimming Should I trim off the sun leaves since my plant is so frickin dense. I’m assuming that the light isn’t making its way down enough. I just don’t want to cut off something that could hurt my growth.

Defoliation before harvesting Hello, I hope some more experience grower would be able to give me a good advice. I’m in week 9 and planning to harvest at the end of week 11. Do you think that defoliating my girls would be a good idea? Should I take all big fan leaves? 🤔
