How do I know my LED is sufficient?
DankGardeneranswered grow question 5 years ago
When it comes to growing cannabis, LED models with 3W chipsets (each individual bulb is 3W) seem to get some of the best yields/watt of all LED models without a lot of worry about light-burning your plants.
With LEDs, always look at the “actual power draw” or “actual power consumption” which is the amount of electricity the LED panel actually pulls from the wall. When comparing different LED grow lights, this is the closest you get to a side-by-side comparison.
Generally, your goal with LED panels should be 50-60 watts per square foot of grow space to get the best results.
OrganicChronicanswered grow question 5 years ago
You know your LED is sufficient if you have 200-300 “real watts” drawn from the wall for a 2x4. The plant might be drooping from cup, I wouldn’t recommend it. Only clones need a dome because they don’t have any roots yet

Seeds everywhere, unsure if this is a result of impregnation from a hermie I had weeks ago that I may have touched and spread pollen unknowingly or stress?I have 2 GDPs from ILGM that now have seeds. One much more than the other but certainly seeds. My question is can these buds still be used for rosin/edibles? or even smoked? And can these seeds potentially be feminized as they may have been stress induced? Or assume bad and toss?3 years ago

Drying Techniques, Which One?...I have a question on drying, what are your opinions?
1)drying the whole plant fan leaves & all
2) drying the whole plant with only fan leaves removed
3) wet trim, cutting each branch off separately & then hang drying
I'm looking for best quality flower not the fastest.Other. Harvest - Drying

What to do before harvest?I've been planning to chop my girl in 2 days (sunday), been flushing since 1.04 and watered yesterday (thursday) for last time. Would it be beneficial if I moved the harvest 2 days later, (for total 5 days without water + 48 hrs in dark) would that make considerable difference?Week 11

Drying tempsI’m close to being ready for harvest. My temps in my tent run from 78 degrees due the day and 72 at night. The lowest I was able to get it was 70. Would 72 degrees dry too fast? I’m in an apartment ok the second floor so cool spots are unavailable especially during the summer.Other. Harvest - Smoking

Fioritura troppo veloceChiedo un vostro parere..
È possibile che all'incirca alla 5 settimana di fioritura ci siano già tricomi ambrati sulle infiorescenze? Se fosse così dovrei raccogliere nei prossimi 5 o 6 giorni. È il mio primo ciclo con autofiorenti quindi per me è molto strano.Week 8

Should I wait with the harvest?I think my plant still has a week or more to peak, but here's my dillema: I've started flushing too early, almost 2 weeks ago, so how should I proceed? Should I keep giving her only water, or will such long time without any nutes be harmful, in that case should I give small dose?Week 9

Which Sativa next?Now that I've fallen in love with Jack Herer and realised it's probably the first sativa I've ever smoked (I was raised on moroccan hash and stuck to it ever since), which one shall I grow next? Jack Herer seems to inject me with a dose of happiness.Week 20
