36W UVA/Blacklight for seedlings?
JadedFurystarted grow question 3 years ago
I have read that Blacklight does not help the plant grow and since I do not know much just yet, I would just like to confirm the fact and whether my 36W UVA lamp would assist with the seedling stage?
I am still learning and tried making my own grow dome π¬π

Hi Jaded, it will help the seeds germinate for sure, i use a propagator like you and it really helps in my experience. Cannabis comes from very steep mountain ranges in Thailand that trap clouds of fog and humidity so that's why the plants really like high humidity. Anyway the blue UV will only help until a point, then the plant will start showing signs of weakness and it could die. try using any light you have around the house and put it as close as possible to the plant without burning it, it will complement the blue UV very well in the vegetative stage. After that, probably you need a better solution. Hope this helps ! π
Organomananswered grow question 3 years ago
Plants do need UV A and UV B for health, also white light, meaning using a UV light on its own is not sufficient for proper growth.
Also, your seedlings do not need extra humidity or a humidity dome, cannabis is not a rain forest plant, but it does need good air exchange for proper growth, something not achievable in a closed environment such as a "humidity dome".
Only cuttings/clones need hyper-humidity, since they do not have roots for a few days.
Hope this helps,.......

Flush too Early?I started flush on the 16th after seeing that more than 50% of the trichomes were cloudy. Hairs are white still but some buds have a few amber trichomes. I don't want this to couchlock too much. Should I harvest the ripe buds, feed 1 day, and re-flush? Any advice is appreciated!

Is she getting too big for a 2L pot?Is my plant getting too big for the pot? It's only a 2L pot and she just hit 14 inches in the pre flowering stretch.
I didn't think she would get this big, I don't want to stunt her by not repotting when I should have, any advice would be great. Thank you!

Does 72 hrs of darkness really increase the potency of the Trichomes/THC by up to 25%Hi everyone! Can you give me your opinions on doing a dark period just before harvest? Some ppl do 72 hrs, some less and some none at all. Can I get your reasoning for the method you use? And any other helpful info on the subject would be greatly received!Other. General questions

temperature and humidityMy plants are now in the third week and the 18th day. What is the best temperature and humidity for them week by week? Until now, it was 24 hours of light that I want to take to 18 to 6, should the temperature and humidity of the night be less than the day? Thankful.
