studentestarted grow question 6y ago
Wow. Thank you so much for the reply. I have been playing with LUX meter app and my light. I was bit skeptical about the lumens that I would get from the 15W but as it turns out, it receives well enough ppfd. Still skeptical about the spectrum i am having.

Hey bro! 👋😇
Glad to see you've already mastered the app! 😇👍
To analyze ppfd, a special spectrum analysis device is needed, and its price is quite high! Such devices are available in laboratories studying spectra! So in our case, for the average user, analyzing the lighting of the cultivation area is enough to talk about the effectiveness of artificial lighting! 😇👌
Good luck, dude! ✊😇

Wrong light scheduleScrewed up light timing.
Thought I was on an 18/6 schedule in my tent but apparently it was 12/12 from weeks 3-7. It’s close to needing to be switched over to flowering size wise. I switched over properly to 18/6 two days ago and plan to keep it there for an extra week. Yes?

ILUMINACIÓN ALTERNATIVA PARA PLÁNTULAS AUTOMÁTICAS EN EXTERIORI have a reflector and some TCL neon lights to put my autoflowering plants to grow after germination until they're ready to be on the balcony. But it doesn't work. Does anyone recommend a regular bulb that I can use until I get a new reflector? THANKS

Veg/Bloom switchMy plants are 5 weeks from germination, I have flowers and buds forming but I am starting to worry they aren't growing as they should (I want them bigger). I have had my light veg and bloom switches on throughout.
Would you recommend I change over to just bloom switch now?

Slow indoor seedling growth4 days since sprout, issues with light timer, seedlings ended up getting 48 hrs of light after they sprouted, and this AM I found that the timer did not turn the light back on so it got 11 hours of dark last night instead of 6. Could this be detrimental to seedling?

GTMAR 1000watt full spectrum lightI bought a gtmar full spectrum 1000 watt light off amazon, does it really put off 1000watts?? My 4 plants look great except I can tell that some of the under foliage isn’t quite getting enough light, I’m doing some LST.

Is 1’ away good for now? Personal experience opinions welcomeOk Guys. My plants are 6 days old now. And I have them under this 72w light that is about 12” away from them.

Opinions on progressSo this is my first solo grow in a completely new setup (previously only grown in collaboration with a friend). Started off with a cheap blurple light. Very slow start then upgraded to a mars hydro TS1000 2 weeks prior to flowering.
