best answer would be to ask the manufacturer of that light directly

I'd probably keep them max height. Those lil girls don't need much. 👌

Thoughts about harvestingHello guys ! This question is about my Purple Queen Auto.
She's a little bit over 8 weeks old now (5 weeks into flowering) and I really don't know when to harvest her.
I know about the trichrome method but I only have my eyes to zoom haha
So, when do you think she will be ready?Other. General questions

Hopefully I get back lots of "Don't worry! it will be fine" replies!There is a brown resin coming from where the cotyledon leaves are/were.
Is this something I should be worried about?

First time Growing questions- Which pot and soil should I use?
- Should I germinate seeds between wet napkins or plant them straight in soil?
- I live in a hot place (30ºC) – grow indoors first then outside? (cant grow indoors)
- Can I water with tap water?
- How often and how much to water?
Thank youOther. General questions

Should I remove these leaves? Only the ones with the worst signs of the Deficiency?Basically I’m going throw a calcium deficiency in week 7 of flower, feel like I’ve already fixed the issue by flushing with pH balanced water and reading the right nutes to the medium. Overall should I trim these fan leaves with deficiencies? And does my plant look good?Other. General questions
