Its hard to say definitive but they are the best/optimal ranges. So For Clones/seedlings/mothers 200-400 PPFD/PAR is optimal for them. A 400-600 PPFD/PAR is great for early veg to late veg when I say early I mean after the seedling stage. And 600-900 PPFD/PAR is great for Late veg into Flowing Fruiting Stage. Once you get over 1000 your getting into the double ended light and Co2 territory because it Is no longer light limited but carb limited therefor the need for Co2. That's why 600-900 PPFD/PAR is best balanced for efficiency and performance Other factors can have effects on growth as well like environment conditions and the biggest role is genetic. but as for the PPFD/PAR those are pretty much the Numbers most go by as rule of thumb you know. Happy Growing!!🙏

Using a 48x48x80 tent in my basement. Humidity is reading 30%. Have tried all the tricks to raise it and it does temporary then lowers quickly. Reading so much conflicting info. Would a humidifier work in my tent? If so, please point me towards one to purchase. Thanks!

How do you guys check your trichomes? What % of amber do you have? Do check for milky/amber on the leaves or the bud itself? I have a microscope but it’s very hard to use unless I trim a little piece of bud or leaf off and inspect it on a table with my microscope.

The latest photos show the growths in Bruce Banner that look like hermaphrodite eggs. Do you think this is eggs or am I wrong? Would you destroy the plant at this point or break off the eggs and continue to observe? For good, I must destroy the plant. But there is still weak hope

End of my 7th week of flower with this indica-dominant Green Crack. Breeder says 7 to 8 weeks. Trichomes are mostly cloudy, although a few are still clear. 1 or 2 amber ones. I want an energetic high. Just posted a new pic of plants. Harvest in 3 days or wait 1 week?

Hi everyone, anyone have any suggestions on when to put this little beauty into flower? I’ve never grown such a small plant and I’m not going for quantity here just quality. On one hand I’m thinking I could flower right now at 8 weeks but I also do not have experience mainlining.

I’m a bit unsure, re: bubblicious, do you think i should fim or top or leave them at this point? as they are pretty squat also do you think putting the full spectrum lighting on now is ok as i have done? i figured as its auto it wouldn’t make a difference, more light more growth.

Why is this Power Plant seedlings growth slow? Is it due to watering or just the fluctuation in weather conditions even though the temperatures remained consistent. Grow along with me.... I'd love some autoflower tips as this is my first autoflower grow.

What do you guys look for when it comes to harvesting? I have a jeweler's loupe but my hands are too shaky to use. Was thinking Yellow Marker was getting close since her pistils are receding into her buds and she is nice and fat. But I definitely don't want to cut her down early.

Defoliation - fan leaves Yay - to help with RH and focus plants energy on colas Nay - because plants need their leaves to photosynthasise and better to remove larfy bud sites instead A well known Phd in plant biology is firmly in the nay camp What do you think?
