That 3rd pic most definitely, no big deal it all smokes.

This is what I meant by low pressure earlier. Higher light puts more pressure on the plant to grow .The more light you give them the more perfectly you must balance the “cardinal parameters” of growth to make practical use of that light.


If any of those 9 factors is lacking you will see less benefit or even harm from increased light.

Sweet. Thank you. Pretty sure my limiting factor is co2. I feel good about everything else on that diagram. Thanks for that, going in my “hobby” folder :joy: when i had the sensor plugged in it was often high and pretty regularly around 1000. I made a gamble that genetics/co2 may enable me to push a bit. The sour D looks totally fine to me but im just gonna follow that schedule and keep DLI in normal range moving forward. VERY confident my temps are good.

Really appreciate yall taking the time to answer my incessant questions.

Well worth the hour if you have the time. Dr. Bugbee has lots of good videos but this is a great place to start.

So i watched that, when he was explaining ppfd outside and the upper limits, I was thinking, “I wonder what the ppfd outside is at 5500’?

At this elevation a sunburn occurs in 10 minutes. I mentioned this before but if i dont use the 40% shade cloth the leaves pray so hard they stand almost straight up.

High elevation sun is no joke boys and girls

Well it’s a nice clear morning up here at 6700’. I’m getting a direct sun reading around 2300 PPFD. Last summer I did some playing with plastic row covers with decent results. I found the shade cloth can be a little too shady for cannabis unless you take it down in the evening and put it back up mid day, but helps a lot with heat on the hot dry days.

I always make the joke full sun doesn’t really mean full sun here in the high desert. I get so jealous of the people that can harden a plant in an afternoon. Half your plants just fall over dead if you try that here.

I grew this outside last summer. Ended up trashing it full of worms and bud rot right before harvest.

It was 36” tall and 60” around. You can see the 40% shade.

Impossible to grow tomatoes or peppers (only thing grows good are radishes and onions actually) without that shade. It completely changed my garden.

That sucks, I love the monsters you can grow outside, but it definitely has it’s own challenges. Last year I had a hail storm rip half the branches off then just as they started growing again and flowering we got another worse hail storm. I ended up with 2 oz of dirt weed from 4 plants :sob:. sometimes shit just happens. I never had much problem with my peppers, but chile is a religion here so it’s pretty easy to get local seed that grows well here. It’s inside I have the problems with peppers. I’ve had the same experience with the tomatoes though. I have a line of trees on one side of the garden for shade, but it hits the garden a little late in the afternoon. Earlier shade would be nice.

Jalapeños grow well. Green peppers are a freaking nightmare. But im determined. I realized yesterday every green pepper i yank off my plant is $1

Bruce banner is struggling. One of my tops just shriveled up and died. Waiting to see if it will grow out the node below. Nothing so far. Then playing with it today the branch on the other side almost completely snapped off against almost no pressure, just popped loose :man_shrugging:. Used some raw honey and teflon tape we’ll see.

Both slightly yellowing between the veins too. Never had trouble in early seedling before. I may be starting the hydro sooner than I thought :joy:

Seems like all but the one fan leaf are already recovering, everything was completely sagging last night when i taped it up, it was only hanging by a string. If it does survive, how long should I leave the tape?

She’ll probably be just fine. Cannabis is pretty damn tough. You can take the tape off when the branch start’s growing again. Usually a week or two. Might dial back the light a tad too to let her heal.

Did you get pics?

Up until you see the branch getting bigger and the tape starts to “strangle” it… Personally, if it doesn’t restrict growth, I leave it in place. :nerd_face:

Of the shriveled up top? No. It turned brown and quit growing tho. Assuming it has something to do with my mismanagement of this particular soil.

From the description I’d guess there is a soil temp or moisture issue, but it’s just a guess. Have you gotten root zone temps on the little ones? How much and how often had you been watering them?

3 Likes

Watering every 3 or 4 days. Root zone temps getting to 79° highest. That soil definitely does hold moisture FOREVER. Watered very heavy not realizing it was organic soil. I was planning on adding first nutes next watering

How much water do you give them at each event? I’m leaning towards under-watering or watering too fast. If the soil gets too dry or you water too fast you’ll end up with dry pockets in the middle that will be hydrophobic or water repelling especially in larger pots.

2 gallons. Thats a lot for how small they are but i figured i screwed up in the beginning anyway cuz you said i shouldn’t be watering to runoff at all. I thought id just flush and reset atp. Ppms are 950 but ph is high. They both have been growing pretty slowly as well it seems. Not a fan of that soil. I think Im about 2 weeks from wizard punch harvest. Maybe 3. Im 40 days into these seedlings from sprout and they haven’t reached the outsidenof the pot yet either. The PGC I tore the tap root and it stalled for a full week and is now past the bruce banner which is wierdly sensitive to it seems everything.

That is probably a bit much. You want to keep the soil moist throughout, but too much suffocates the roots until some of that water is replaced with air.

Some plants are like that. Each plant will have it’s own personality and quirks. I have 3 plant’s all from the same seed stock. One is an absolute monster that just doesn’t care what I do to it and takes up a quarter of the tent and I have another that is 1/3 the size and twice as dense and has to be kept under lowish light with the veggies and watered half as much.

I also live in the high desert. We avg 4” precip/yr even most big snow years we just get drizzle down here. This soil brand literally holds water forever. I think i made the wrong choice, especially for someone that doesn’t know anything about soil. Telling you it would probably hold a gallon for 5 days. It says drought resistant on the bag cuz we are always in drought down in the valley

low RH doesn’t help either.

This is why I transplant a few times. I can increase soil volume as I build roots. In this way I can control the wet/dry cycle. I if I over water in a small pot I lose a day while it dries. If I over water a small plant in a big pot I lose 3, 4, or even worse. I’ve tried starting in the final pot a few times and never got the hang water management those first few weeks. Transplanting just makes more sense in my mind and makes it stupid proof for me.
