started grow question 2y ago
If I use my old aquarium and try to germinate. Would the lamp be sufficient for early stage, or does it have to be a lot stronger?

Te sirve para los primeros días Si ves que la plantula se estira (el tallo se hace muy largo), acerca la lampara o cambia a un CFL o LED de 50W

Do I leave the lamp on 24/7? Or do I keep it turned out for some time?

Hey m8! Pretty sure that would work well for the early days of the plant the Watts of the aquarium would help confirm this statement

Grow Light Advice
Helloo growmies! I've got a question.. I need a new light for vegging (only) in a 80x80cm tent. I am thinking of eather the LIGHTWAVE T5HO 60 CM (48W) or MarsHydro TS 600 (100W) Has some one experience with those lights? Is it worth spending double on electricity with the MH?

Veg/Bloom switch
My 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?

Lighting cycle for VEG stage. Is 24x7 OK?
Hi, Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED Thanks, Mr.STM

Lux Meter Apps on Smartphones
What are your thoughts on Lux meter apps? The app on my Samsung Galaxy S10+ is showing 16,600 Lux at the tops of the seedlings, and converting that to a rough PPFD shows 222.55/umol/s/m². Reading more, 15k-45k Lux and 200-400 PPFD is good for early veg. What are your thoughts?

Does anyone have experience with colas that have been severely light deprived, yet still have trichs?
My ghost nug grew up on the side of the tent blocked from light. She has trichs, looks super light yellow (see pics). My question is, wouldn't this be desirable? Less chlorophyll to wait on before smoking? Has anyone tried to maybe light deprive parts of their colas?

LIGHT SPECTRUM, is that a good one for growing cannabis?
Hi guys, in the future I plan to upgrade from the current 2x2 box/150w LED. I was thinking of a 4x4 area with 500w LED. I came across an interesting 500w led lamp for quality/price and this is the spectrum chart, does it seem suitable for growing cannabis?

I have recently received a lumen meter. Measuring 78,600 lumen over canopy, is that OK? For my other grow, does anyone know how many lumens seedlings need (at about 25000 now) ? I can convert from PPFD or PAR. Educate me! Thanks

How to switch to flowering
It's been about 5 weeks from germination. I think we're ready to switch to flowering. I'm just not certain on how to go about it. Do I gradually reduce 18/6 of the veg light down to 12/12 (over a week?) then pop in the flower bulb? Or do I just make a hard switch?
