Brix! The Quest For Grade AAA Organic Cannabis

[BedroomFarmer]

I’m learning that environment is everything then light then nutes.

Yeah, it's making all the difference. I have to invest in a good humidifier. I think it will make a difference for my wife and i too. We get so dried out when we sleep.

Yep. When the environment is right and the soil is alive and happy, this stuff is super easy. But nothing goes right if the environment is out of check by a lot.

Thanks Doc, ill be sure to keep it in check. They are growing again, hope they speed up. I cant wait to switch.

You can only do what you can do at it pertains to humidity. I know for me in the North East, I won't see 50% humidity again until May. So knowing I sit naturally at 16-25% in the winter, if I can get it up to 30-40%....I am happy as a pig in mud.

30-40 where im at now. Trying to keep it at 40% now but its been in the upper 30s. The growth is better since adding the humidifier

I have succumbed to spraying after seeing my veg cab consistently in the low 20s. I hate spraying if I don’t have to lol. Dude the QBs are awesome I finally got one and it’s only been a day and I don’t see myself going in any other direction lol the natural lighting color alone was worth it.

Yeah i prefer not to spray especially since the pm. The qb are definitely the way to go. I built up my cobs right when qb were coming out and people were experimenting with them. After seeing buck and shiggity i was sold. Better coverage then cobs means i could have built the same light set up i have now with qb at half the price i paid for cobs. I recomend qboards to everyone as they are the latest greatest tech and cheaper then the previous tech which is cob. Cobs are great but you need a lot inorder to achieve the same coverage. I love my lights but i would go qb next time for sure.

I'm not Tomula, so this is just my experience.

I use a temp controller for the vent fan and adjust the humidifier or dehumidifier seperately based on the 24 hour readings. For 3 years now.

The humidity is going to fluctuate 10-20% through the light/dark cycle anyway, so the few percent change when the vent fan runs doesn't seem that big an issue.


I have circulating fans running, and an open fresh air intake. Stale air doesn't seem to be an issue. I don't experience it as stale if I open the door during the dark cycle., but I'm a human who enjoys the 'stale' oxygen put out by plants

Hey thanks! +rep that was so easy i didnt even think of doin it that way.

I think im going to look for a vent fan temp controller, ive seen them for pretty cheap and when i get a proper humidifier ill make sure it has controls to set at the perfect humidity.

Here they are. Got trans today. New growth is kinda strange but i think its growing out of it.

Looking much better now, should see increased growth from here on out. .

Those plants look like they have wet feet? Are the veg containers resting in water?

Thanks pw. I just bumped up the lights, hope they take off soon. I cant wait to flip these ladies.

No no, just used the saucers for watering.

Cool. Nice strong GE drench next and those lower leaves will clear up and things will get going!

 

[BedroomFarmer]

Thanks Doc! Big help as i was gonna do plain water after the trans. They have been drying a lot faster so GE in about 3 days. Just have to keep an eye for light stress but on the right track now.

 

[Pennywise]

Your running real close to my light setup at those settings.

 

[BedroomFarmer]

The lights are hung up pretty high but you think 300 watts is too much? Its so hard to tell how bright or how high up to hang without a light meter. I wonder if there is an app for that! I really dont want to add more stress to these plants.

 

[Pennywise]

I'm running 248w actually at around 14" above the canopy. Maybe dial it down a bit until they get rockin then blast them! .

 

[Graytail]

Roughly 20 watts per square foot at 24" is about right for veg. That's 600-700 umols for Samsung panels and COBs. 35 w/sqft for bloom.

 

[Pennywise]

Good info to have.

 

[BedroomFarmer]

Yes! Thanks GT. So im looking at about 320 watts and get the plants to 24" My lights are set to the highest posistion in the tent because i cant really adjust them. Ill see if i can get some crates to get the plants higer up

Ah, no, that's even better. You're better off keeping the lights high.

It's counter-intutive, but you get a deeper effective canopy if you increase headroom. Turn up wattage before you decrease headroom. Then your half-strength point is deeper. Make sense?


[Edit] I originally posted this from a phone and didn't want to go into detail, but I will now. This is something I've brought up a couple times on other threads and I can see that it's hard to grasp. We know that light intensity falls the farther away we get, and it falls faster the farther we get. The Law is that at twice the distance, you get 1/4 of the intensity. We've found, by measuring real life setups, that with widely dispersed sources the loss is more like 1/3 to 1/2. So, if the light is twice as far away, you'll get 30-40% roughly?

At the top of the canopy in bloom, we want 1200 umols of light, and 500 umols is what a plant needs for good metabolism. 500 is, whaddya know, about 40% of 1200. So if the bottom of the canopy is getting its 500 minimum and the top is getting 1200, you have a well lit canopy - very efficient.

That means that if you want a canopy 2 feet deep, you want 2 feet of headroom. Right? Because at twice the distance, the bottom will get 40% of the light the top gets. If you increase headroom, it deepens the canopy. If the tops are 3 feet from the source, then the bottoms can be 3 feet farther away - twice.

My latest setup has been working exactly like that. My lower nugs are now no different than the upper ones, and they're all denser. I'm running 700 watts for bloom in a 4x4, for 43.75 watts/sqft, and I have the lights mounted at 6 1/2 feet off the floor and I can run full canopies 2-3 feet deep. They started with over 3 feet of headroom and grew up to the panels. I have hard nugs that grew the entire time 3 feet from the lights.

Whatever your headroom is, is what your effective canopy depth will be.

Even more great info to have! Good stuff GT

 

[Pennywise]

Excellent I'm going to have to setup my QB's a little higher on my next grow. Thank you GT for tutorial.

Man GT! Tons of great info! Thank you. It makes perfect sense to let the plants grow into the light. Thats kind of what i was going for putting the cobs up so high but i had no idea it had that many benifits.

Your setup is pretty much identical to mine. The cobs max at 700 watts in a 4x4 tent. Right now my light is 4' 10" off the floor but i think i can get them up a little higher. Im gonna lift them up a bit more and turn the lights up some. The light penitration on these cobs is insane. I look forward to top quality buds from top to bottom. i blogged your posts, im sure others will find it very useful

There back on track! Trying to do some pinching but the stems are so stiff. Im going to need a stick to press against.

 

[Pennywise]

Night and day change, looking happy now!

 

[BedroomFarmer]

Thanks! The humidity seems to be making the difference, will give GE soon and hopefully they explode!

 

[Pennywise]

Yep environment is everything, I have a portable AC I'll use this summer. Hopefully that lets me run through the hotter months.
