36W UVA/Blacklight for seedlings?
JadedFurystarted grow question 4 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 😬😕

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 ! 🚀
Organomananswered grow question 4 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,.......

Dehumidifier recommendationsAny recommendations about a dehumidifier for the 4x4 grow tent? I think even with vacuuming run-off more frequently, I won't be able to get humidity consistently down below 60%. Amazon has some in the 45-90 USD range...Other. General questions

Very slow seedling growth into Week 2, grew with only one healthy cotyledon...The #2(Pic 2) Pheno of my Purple Haze is a bit stunted/very slow growth into Week 2 - 3 compared to #1(Pic 1) Pheno. Is this anything to be worried about? I did germinate a #3 Pheno seed + 1x Jack as a backup in case this one doesn't make it, is there anything I can do to help it

Getting better yields from small plantsShe's well into flower but in my opinion, she's too short for it. What can I do to make the flowering process go as well as possible considering her short 15cm stature?
The side nodes are barely 5cm tall and are already flowering. With no new leaves growing it might get rough.

Are these males?Are these clones turned male? I cannot tell. They are clones from nice well established mom. They are, and have been very weak and not really doing much for weeks as I've paid much more attention to mom. Should I ax these? Don't have seed room.
