I'm pretty pleased with how it's coming together.

do you track your ppfd at all? I think your led plant photos look great and I have struggled with ramping up the leds in flower so curious if you have ppfd numbers through ramp up. Thanks

Hello, I've got a led lux meter for a rough guide.

I also have problems ramping up power.

So now i flip them and keep treating them as vegging 20/45k over the 1st 3/4 weeks only increasing the light gradually over that period, once they actually have flowers to grow i start to squeeze the most from the lights (Wk 4/5)

I found it's better to take it easy to start with, pre flowering doesn't require masses of light.
If you/me bleach them early on we're then stuck with them limping through a whole crop, if we're a bit late they're healthy throughout and running on full steam when needed.

Its not very scientific but I trust what my eye's are telling me.

I've also found when I increase intensity i need to increase the ec with it, if i don't increase it they'll look like shit within a day or two, the 1st sign I'll see is that pale yellowish look in the fresh growth.

Week 1 im at around 35%, week 2 im pushing up towards 50%. Week 3 im closer to 60-65%, week 4 i push up to 80-85% then during week 5 ill get to 100%. This has been the schedule that showed the least stress. I also dim to 90% for the final week. Gotta be able to measure your light though.

Modern man beating the HPS user into extinction? :)

I'm not sold on this ramping up. I found solace in the last years studies, showing a shift away from dimming. I don't see any gain from full lighting plants I didn't grow fully. Any reduction in growth early on, can't be won back later. The stretch is when the frames develop, and when it's done, it's done.
Perhaps what I'm thinking about is low light early though, and what people are actually talking about is something else. More like doing my usual HPS grow in the 20th century, and adding more lights in the final weeks. Not keeping lower early, but going higher later. When judged against a base line.

I'm not a believer in waking them slowly, or fake sunsets.
I think this won't make sense to me, until I see some ppfd targets through these stages, and the veg period before.

I have lowered lighting for holidays and such, and the loss has always been greater than expected. I get X number of weeks, and must use them fully.


Off topic:
The 600w per meter rule gave about 1000umol. The distribution was terrible though. The HPS user was passing that 2000umol mark under the lights, that the LED user isn't. It should be no surprise, to see the HPS user put some buds on the table that are great. While at the same time, the HPS user is chucking away buds further from the light. While the LED users has a lesser spread of results. Not having the 2000umol area, but also not having the 200umol area. The result of this difference, is judged by the individual. I like the 'all you can eat buffet' but the michalan star goes to a portion I can fit on a spoon. I'm still messing about with HID in an LED grow. I guess it's progress from messing with LED in an HPS grow. I did box the HPS away though for a while. Then get it back out.
Please don't hurt me :)

I feel for me and a lot of my smoking friends it has been the opposite here.
In the last 10 years before leds conquer the scene, 90% of what I bought in the street was fire...
Now I just skip it all, it's all mids.
Finally found some nice outdoor bud, made oil outta it, cost pennies and better than any led/hps grown here
I don't know how to explain it, the distance between what some people feel about this subject to other people is elusive to me.
