Do you follow VPD throughout flowering? I was considering it but I thought humidity should be a lot lower in flowering but according to the chart i should be around 65 humidity for a room temp of 75deg F and that seems kinda high.

It took me about 20mins to figure out what you guys were talking about since i'm pretty new to the scene... I'm curious to know what the difference in yield might be for a 5%-10% increase in efficacy. @Greengenes707 , have you grown with the CXA3070's? and if so, what was the difference versus...

Thanks for sharing. subscribed.

Hi, Cree's website states that the maximum efficacy for the 3590 is 174lm/w . Can someone tell me which MA this is at? I'm looking at the "relative luminous flux" charts and calculating my lm/w based on that data but i'm wondering how are doing it? Thanks!

nice. can't wait to see the outcome. where did you find those heatsinks?

Is it possible to wire up two drivers to power one cob?

thank you!

What about the reflector adapter?

Hi, I've order some VERO 29 and . From looking at the datasheets it looks like there are two 3mm holes placed 43mm apart for both the COB and Holder. Are the same holes used to mount the cob and the holder? thanks!

is it me or are your leaves only showing 3 petals?

gotcha. thank you sir!

@CobKits for the record I think I was confused because I thought I was buying "constant current" drivers (HLG240H-C1750B) so i assumed that I was dimming the voltage and not the current. thanks again for clarification

Awesome I was hoping i was wrong. makes things so much better!! Thank you.

I think this is it because they do appear to only form on the older fan leaves. Should I be removing these leaves since im in week 7 now to promote nug meat? Thanks for your reply. I Don't think its thrips. had these before and i dont see the black dots or anything moving on the underside of...

From reading threads on RIU i know that pairing up more cobs with a lower amp driver such as 700ma is more efficient than running it at 2100ma. But lets say I use a 2100ma driver and dim it so it's drawing the same power from the wall as a full power 700ma driver would it have the same...

Not really. I've had thrips before and i don't think its that. Have 6 plants total and these "silver" leaves only appear to be on the 3 white widow strains so I thought it was because of the strain at first but after looking closely it looks to be like some sort of problem. =/

Hi, I'm in week 6 of flower and i've noticed the leaves on my plants beginning to look silver. The strain is white widow. Would love to hear any helpful insight on what this might be. Thanks in advance!

Hi, popped 3 seedlings on november 1 and one of them looks like it might have sacs. Could you guys help me identify this?

Say you have someone like me, who's a noob and experienced nutrient deficiencies/lockout during the middle stages of veg. If fixed, before flowering, would there still be a difference in harvest vs a completely healthy plant from seed?

Hi, I know both phases play an important role in achieving a great harvest, but which do you guys think is MORE important? This question came up after watching one of @Growmau5 videos when he mentioned something about flowering was the time when your hard work has paid off and you get to see...
