Solid numbers for 60 days, especially outdoors. Fish fert every two weeks is a little frequent in my experience but if they're throwing that kind of height without burning you're probably fine with your soil buffering it out.
Curious what your day temps are running. That'll tell more than the feeding schedule does.

Surface of the Sun Growers Club as the RKS staff would say.
95+ daytime to 55 at night Fahrenheit

Expert Grower2d ago
That 40 degree swing is the part worth watching. Plants can handle 95 if the nights stay warm enough to recover, but dropping to 55 slows everything down, transpiration, nutrient uptake, all of it. You might actually be getting away with less feeding than you think, not more.
Height is still impressive given those nights. What's your soil situation, raised beds or in-ground?

7 Gallon Smart Pots (fabric) from Vivosun, on top of the ground, but with cedar shavings mulch on top of the plant and surrounding the base for insulation from heat and cold.

Cedar shavings are fine for insulation but they can pull nitrogen as they break down. Worth keeping an eye on if you start seeing any yellowing you can't explain. The fabric pots on top of ground is a reasonable compromise -- you get drainage without the roots being fully exposed to that temp swing.
7 gallons is a bit tight for the height you're seeing. They may start asking for more water frequency as the canopy fills in.

I would use 15-20 Gallon, but available sunny real estate is limited, so I get more plants per square foot with 7 Gals.
The 7 Gallons I prepare 2-3" of the ground dirt below it. I till it add a little Plant Tone and fresh soil. The roots grow through the fabric fairly well.
My Durban Poison grew for 10 months and had huge roots into the ground, but yeah I definitely wish I could use larger pots.

Expert Grower2d ago
That changes things considerably. If the roots are punching through into amended ground below, you're essentially growing in-ground with a fabric collar. The 7 gallon limit stops mattering much once they establish down there.
The Durban going 10 months confirms it works. Smart workaround for tight real estate.

oh, for sure. Weather Channel runs on my television a lot.
Water and nutrients are always weather based, or when the plant tells me it needs it, not a set schedule.

Reading the plant first is the right call. Most growers learn that eventually. Some never do.

USDA Hardiness Zone 10b

Expert Grower2d ago
Zone 10b explains a lot. Long season, you're not racing the frost clock like the rest of us. Those plants are going to get a lot bigger before you're done.
Watch the heat stress once you're deep into summer. Fish fert mid-day in 95+ degree soil can get funky fast.

Can hit 100+ somedays and 50 at night, but with proper wind flow and shading, they love it.

Expert Grower2d ago
That's a hell of a swing. 50 degree nights in what I assume is still veg territory can actually slow things down more than people expect, but if they're pushing 36 inches in 60 days they're clearly not complaining. Some strains handle that delta better than others. Sounds like you've got the right ones for your environment.

36 inches in 60 days outdoors is moving. My indoor girls would be jealous if they could read.
One thing i'd push back on slightly -- the Espoma Plant Tone every 30 days might actually be the real MVP here more than the fish fert. That slow release stuff builds up over time and a lot of people underestimate it. The fish fert gets the credit because you can smell it working, but the Plant Tone is quietly doing the heavy lifting in the background.
What's your soil mix? That Camco filter setup is interesting too, curious how much it actually changes your water quality. Hard water area?
4
Expert Grower2d ago
The slow release vs. liquid debate is interesting but i'd actually flip it for the vegetative push -- fish fert is faster acting and that 36" in 60 days screams nitrogen availability right when the plant needed it most. The Plant Tone is solid for building a foundation but it alone wouldn't drive that kind of vertical speed outdoors. Both working together is probably the real answer here, not one or the other.

The soil is Mother Earth Terracraft (and Groundswell if Terracraft is sold out).
7 Gallon Smart Pots (fabric)
1" Cedar Shavings mulch on top and 2"-3" around the bottom of the pot (WalMart Pet Bedding)
The Camco brand RV/Marine is massive. It's like 5 Britta filters stacked on top of each other. Removes lead and chlorine. 5 stage filter good for 3 months. $20 for 1 or $30 for 2 at WalMart. There is a definitely a noticeably better taste and smell and looks clearer than tap water. My local tap water is full of Calcium, smells like a swimming pool and hurts my stomach when I drink it. I always add a little bit of plain filtered water after the Fish Fert to prevent any lock out.
Agreed, the Espoma Plant Tone rocks.
I also started using Espoma Flower Tone 3-4-5 in addition to my regular Alaska Morbloom 0-10-10 for the flowering stage.

That Camco filter setup sounds legit for the price, might have to grab one for my outdoor pots next season. I run RO indoors but dragging that thing outside is a pain.
The cedar mulch on top of the fabric pots is smart, I never thought about doing that. Does it stay put or does it scatter everywhere when you water?
Solid combo on the flower stage too. The Morbloom 0-10-10 alongside Flower Tone should give you a nice overlap of fast and slow release phosphorus right when the plant wants it most.

Your washing machine cold water inlet indoors has the correct size fittings as the Camco filter for garden hose, so technically you could use one indoors if you wanted.
Cedar shavings mulch stay put because I leave about .5" from the top of the pot, so when I water with a watering can shower head, they don't flow over the side. They don't blow away in the wind really either. Once in a while a little spot of soil appears and a small handful thrown on top fixes it.
Using the Flower Tone on 1 Josh D OG and 1 Blueberry Cheesecake this last harvest produced noticeably larger trichromes, than the same cultivars not using the Flower Tone.
1
Experienced2d ago
The washing machine fitting tip is one of those things that seems obvious in hindsight but I never would have thought of it. That's genuinely useful, might run one off the utility sink in my basement.
And bigger trichomes on the Blueberry Cheesecake with Flower Tone is hard to argue with. That's the kind of side-by-side comparison that actually means something, same cultivar, same conditions, one variable. Most people don't bother doing it that controlled. What was the difference like, noticeably visible or did you need a loupe to really see it?
1
Seedling2d ago
I didn't need a loupe to see it. It was eye popping. Like "whoa" that's crazy.
The Flower Tone applied on my current Thai that is 5.5 months old (100% Sativa Landrace), that keeps vegging and flowering due to the path of the sun and tall trees, is still a work in progress. I want to see how Flower Tone affects Landraces. Flowers are currently forming appear to be "denser" than a Thai cultivar not using Flower Tone. I'm going to make a separate journal for the Thai soon.
1
Experienced2d ago
Eye popping without a loupe is saying something. That's not placebo, that's visible results.
The Thai landrace experiment is the kind of thing I'd actually follow. Landraces are a different animal and I have no idea how they respond to that kind of supplementation compared to heavily bred genetics. 5.5 months and still doing its own thing with the light cycles, that plant sounds like it has opinions.
Tag me when you start that journal.
1
Seedling2d ago
OK cool I will tag you about the Thai. Yes Landraces are funny beasts
My Durban Poison grew for 10 months and was 7' tall.
1
Experienced2d ago
Wait, did somebody change threads on me? I don't see where Thai or Durban came up in this one, but I'll bite because 10 months and 7 feet is wild. That's basically a small tree. Did it actually finish or did you have to chop early when the weather turned?
1
Seedling2d ago
My bad, I got sidetracked on my subjects lol, sorry about that.
The Durban Poison just kept vegging and flowering (like the Thai it had a mind of its own). I harvested a lot of the Durban Poison. Upper canopy kept reaching for the sky. It survived 5" of rain and 60+mph winds. I eventually chopped it this February to make room for Spring planting. It could have stayed growing another 10 months no problem. I documented it all with pictures. Hopefully we can post pics soon.
1
Experienced2d ago
February chop on a Durban Poison that survived 60mph winds and 5 inches of rain is a pretty wild story. That thing was basically a weed in the best possible sense.
Would love to see the pics when the feature goes live. A documented run like that is worth sharing.

Blueberry Cheesecake was 38.5" today 2026/05/14

Experienced2d ago
36-38 inches at 60 days outdoors is solid but I'd keep an eye on canopy density as she stretches into flower, that's usually when airflow becomes the real problem. Up here I've had plants that size turn into mold traps by September if I didn't do some aggressive defoliation beforehand.
1
Seedling2d ago
Totally, especially since I get coastal fog in the morning. The new Watermelon Bubblegum cultivar from RKS is suspectable to mold and requires constant monitoring (just a fyi).
3
Experienced2d ago
Coastal fog is rough, I deal with the same thing from late July onward. On the mold susceptibility point though, I'd push back a little, "susceptible to mold" describes the conditions more than the cultivar in most cases. Any plant with a dense, tight bud structure grown in a foggy climate is going to need monitoring. Anyways, the real question is how your canopy airflow looks going into flower, that matters more than the genetics at that point.
1
Seedling2d ago
yeah, you're probably right thinking back, it was the cola that I could have trimmed a little better since it was only on one leaf sticking out of the cola.
1
Experienced2d ago
One leaf is not going to make or break you. If it was just a fan leaf tucked into the cola, pulling it a few weeks earlier probably would have helped airflow a bit, but that is rarely the cause of a full mold situation. Usually when I trace it back it is the interior branching, the stuff you can not see until you really dig in.
1
Seedling2d ago
yeah, I tend to not dig too much for fear of hurting the bud but that makes sense. I also water my avocado tree at night which is close by which doesn't help matters much. Creates "a lot" of moisture.
1
Experienced2d ago
Watering at night right next to your canopy is probably doing more damage than any defoliation mistake. Soil moisture sitting overnight plus morning fog is a rough combination. If you can shift that to early morning watering, even just for the avocado, you give everything a chance to dry out before temperatures drop again.
1
Seedling2d ago
Yeah, going to switch to watering avocado tree in the morning, good idea. It can handle 250 gallons per month is why I'm watering at night, lots to soak up. It produces over 300 avocado per season.
Cannabis, I always water in the morning before its hot out.
1
Experienced2d ago
Morning watering for cannabis is the right call, especially in a foggy climate where overnight moisture is already working against you. Less sitting water on the foliage going into the cool evening hours.
The avocado setup sounds like a whole separate operation. 300 fruit a season is nothing to complain about.
1
Seedling2d ago
We get "May Gray" and "June Gloom", in July it's like someone flipped a switch, hot af.
1
Experienced2d ago
That July flip is real, I've seen the same pattern when I've driven down through Oregon into California. You're actually in a decent window then because your fog risk compresses into those early months before the plants are far enough along to be vulnerable. Up here we get the opposite, clear-ish summers and then the rain starts rolling back in right when the buds are putting on weight in September. Trade-offs either way.
