So I would consider myself intermediate in terms of knowledge pertaining to the cultivation of cannabis, maybe a little bit more advanced when it comes to LED technology. However, the only time I have ever used fluorescent lighting for anything other than light, is when I used to breed bearded...

Yeah, you have to measure light a little bit different when it’s angled like that but you can still use the apogee. The apogee actually has an angle correction cosine programmed in, for corrections of 75 degree angles. IIRC, if you connect the mq-500 via USB, you can modify the angle of the...

Ah, yeah I understand that for sure. I work in sales and this year was a bit slow in November, so I wasn’t able to do my usual Black Friday spending but I did spend a few hundred on seeds that I probably shouldn’t have lol. if was in the market for a par meter, I would go with the Apogee...

You’ll have to run a grow log on here once you get it. I did some reading on it a few weeks back and I love the concept. Some of their advertised specs were a little wonky, but I honestly don’t think it was intentional, I think they probably just got a bit confused with some of the testing they...

730nm can be used two ways, as a flower initiator, or to create the Emerson effect. There wouldn’t be any benefit to using it before lights on, at least that I know of. the Emerson effect is using 730nm in tandem with 660nm. The combined spectrum results in increased photosynthesis. what I...

That’s a very mild picture of leaf septoria, if it is at all, any case I’ve seen has always been accompanied with very sickly looking leaves, as well as brown/black spots mixed in with the yellowing. Unless I misunderstood him, OP says the yellowing stopped whenever he adjusted his feed...

A good foliar spray can help prevent PM. I use Optic Foliar Overgrow myself. Does your humidifier put out warm mist or cool mist? Just make sure to keep airflow running through your canopy, and if your buds are really thick, you may lower it a little even if the VPD checks out, as long as you...

Of course! If you don’t already have an IR temp gun, I would recommend getting one to read your leaf surface temps. They’re only about $15-20 USD on amazon or hardware stores. You can kind of guess until you get one though, usually under LEDs your leaf surface temp will be ~2 degrees F cooler...

Here’s some good reading on VPD https://www.cannabissciencetech.com/growers-and-growing/understanding-vpd-and-transpiration-rates-cannabis-cultivation-operations

my guess is heat stress. That’s pretty warm, and IMO 45% Rh is too low for temps that high, even in flower, except for maybe the last week or so. The ideal solution would be to find a way to drop your temps. If not, I would bring up the humidity a bit. 45rh & 32 degrees Celsius would put your...

Ice cream punch was heisenbeans, unfortunately he left RIU to run ChuckersParadise. He has a YouTube channel, where he uploaded a video showing all the of his parent strains and explaining a bit which ones stretch, which ones yield, etc.

It definitely does look like he’s been feeding too much N, but I don’t think I’ve ever seen N toxicity cause bumps like that. i could be wrong though, not afraid to admit it lol.

That’s actually exactly what I had in mind for the construction of the room. What did you use to build that? I’ve got QBs in two tents and a mars hydro sp250 in the other lol. I could probably upgrade the sp250 to something with Samsung diodes, but it seems to be doing pretty well so far (got it...

To me, it looks like where trichomes started coming in but are having trouble due to poor ventilation or heat stress. What are your temps and RH like? How often are you bringing fresh air in? What kind of light are you using and how close to the light is the plant?

So up until about a year and a half ago, there was no way to legally grow in my state and the punishment if caught was typically 10-15 years, so due to paranoia, I have never kept mother plants myself. Now, with two medical patients in my household, we can grow a total of 24 plants. We’ve got...

this is what I’ve been discovering for myself. Anything that says skunk either come out smelling gassy or fruity. seems like I’ve seen more RKS phenos coming out of cheese strains than skunk strains

I’ve actually got a couple OCxCD growing right now lol. Do you remember where you got the SLH from? I was thinking of trying Lemon Jeffrey from Irie Genetics but I’ve never actually ran anything of theirs.

Oh man, I bet that will be good. I’ve yet to grow anything of theirs but I’ve heard good things. And an S1 at that? I’m in.

Here lately, I’ve been Doing the beginning legwork for two “passion projects“, finding a good source of seeds for legit cuts of NL and of skunk as well (want to find something that throws RKS phenos). This weekend, I’ve been doing a lot of thought for strains I have really enjoyed in the past...

Update on my two OCxCD plants, this is them at day 22. Almost ready to have their heads cut off. Check out them 7-pointers! #2 has been a beast since about day 10, they’ve both been growing like crazy but GD! Def gonna keep some cuts off of #2!
