I'm not clear on why there's an interest in dry roots but chacun a son gout. "if you start your plants directly in 5Gal the roots will be stretchy and weak for all the grow." I can't think of a reason why this would possibly be true. I start my plants in a res that hold 28 gallons of...

Plants grow roots to anchor the plant and to take up water, and are used to exchange chemicals with the grow medium. If roots are not in the grow medium, they are not able to function as roots. I believe that was @Griffon is saying is that the water level should be a couple of inches below the...

Got it. I went back in the thread to checkout your setup. You're able to drain into a floor drain?

That's the situation with any system that uses a mechanical (or digital) device. I have a spare water pump and a spare air pump. I rotate them every few grows, just to keep the dust off the boxes. :-)

You're doing what you do because that behavior and perspective is why you are where you are in life and your career. It's only natural that will bring that perspective into growing cannabis. It's a plant. <===== repeat 5 times. Yes, the meters that we use have larger inaccuracies than...

Plants stretch when they're not getting enough light. The stem on that plant is very slender so I suspect that it's not enough light. Light is how a plant makes food. What light are you using, what's your dimmer setting and hang height? Do you have a light meter? What are the details on...

That's about right for a plant that size but the plant is the best judge of that, right? What's going on with #1 and #2? What throws me is their branching. I haven't seen that in a cannabis plant.

Sounds like you're right on track. Good to see that.

#4 - the last photo - is looking pretty good. #3 - has curled leaf edges but that's not a light issue. When plants get too much light they roll the leaves inward, not just the very edges of the leaves. Are they, perhaps, still in the process of "de-canoeing" (new word). #1 and #2 - are a...

You must have dated women in SoCal. 8-) That was just too easy. Speaking of easy, you must have dated…

In an early post, you mentioned that the RH was in the 50s. That's dry for veg. With a VPD of 1.3+, your plants are being forced to transpire a lot. A VPD of 1.3 is good for md-flower but it really high for veg. Also, you said that the plants were at 22k lux. That's OK for seedling but what...

Well, yeh, that's a large plant so that paper should help. And if you need help getting smoking of that cannabis, rest easy because we're here to help. ;-)

It took a while to find it (it's available here) but the paper (attached) might be interesting. They studied "large" plants but I suspect that there's a similar impact on plants grown indoors.

No idea if that's even a PAR meter. I suspect that it's one of the meters that uses a gallium arsenide sensor to keep price down. 90° temps - yeh, that's tough on cannabis but the other side of the equation is RH. If you're not keeping RH at 80%±, that's a lot of stress on the plant. Add in...

300-500 is right in the ballpark but if the leaves start to curl or rotate to a vertical orientation around their petiole, back it down a bit. Been there, done that. :-)

Will it reduce yield and quality. If "quality" is secondary metabolites, I've not seen anything that indicates that. Given that blue heavy light in veg will tend to increase branching, it might be arguable that it could increase the mass of secondary metabolites but my sense is that would be an...

The biggest change will be in "morphology" - plant shape and development. Going to a low power light will reduce growth but the advantages of using a blue heavy light are that plants grown in a classical "veg" light will tend to be short and compact with lots of branches and small leaves and...

Nice tent and nice light! My grow is in a 2' x 4' tent and wish I had the room for a larger setup. In terms of light intensity, I haven't see a marked difference between autos and photos. Both autos and photos will thrive in PPFD's >1000 but I have only run photos at >1100. I grow in hydro...

Instead of the $50 light, get a Vipar XS-1500 Pro for about $90. As soon as I saw your plants, it was either you've hacked off all of the leaves (growers love it, plants suffer) or the plants weren't getting enough light. You've mainlined the plant and, in doing so, you've removed a lot of...

Oh, good, it does gallons! ;-) Interesting point about "same factory with a label slapped on it". Maybe that's what's happening. There's not a lot of high tech in a water chiller and they do look an awful lot alike. Ya gotta wonder. Regardless, congrats on finding a good buy!
