Haha they're's a story behind it

I have a couple like it. So far I see no benefits.
....@100% perlite hempy bucket gardeners....
frequency of watering in 5 gal bucket?
amount of water applied @ each watering?
daily watering , or every other day?
1 gallon of water, per plant, or more, or less, per watering?
...............................................................................
100 % perlite 5 gal bucket
6 plants = 3 - 5 gal water everytime depend on how thirsty they are
every other day watering, sometime every other / other day.
&coco:
ph - 6.1-6.5
ec - 260
total organic matter - 96-98%
cellulose - 20-30 w/w%
sodium - 78mg/l
potassium - 210 mg/l
calcium - .50mg/l
ammonium - .40mg/l
chloride - 70mg/l
sulfate - 11mg/l
carbon:nitrogen ration - 80:1
air-filled porosity - 9.5-12.5%
total pore space - 93-95%
lignin - 60-70 w/w dry%
phosphorus - 4-8mg/l
mag - 4-6mg/l
fe - 5-8mg/l
nitrate - .3-1mg/l
water-holding capacity 80-88%
color - light brown
appearance - earth granular w/ short fibers
perlite:
immediately above a water reservoir, holds 30% of its volume as water.
@ 20cm(8") above a water reservoir, perlite holds 19% its volume in water...
50/50 coco/perlite =
*coco water-holding capacity 80-88%
*@ 20cm(8") above a water reservoir, perlite holds 19% its volume in water...
maybe fed 1/5 volume container, every 2 days... full strength fert.
maybe, run-off become 2" water reservoir...
maybe passive hydroponics, using sub-irrigation of run-off as buffered res...
maybe ph down to 5.0-5.5, ec 1.0-3.0+...
Agreed, though I've never used coco slabs.as long as you make sure the plant has plenty of roots when you plant it, i've never noticed a break, or adaption phase beyond a day or 2 at most. the only time i have had this happen (longer adaption phase) was when i planted clones without a good root system directly on the coco slabs, for some reason this causes a lot of wasted time.
My feelings exactly.as for the potential benefits of adding perlit, i see none. just more work for no added benefit.
Yup, pretty much reiterates / confirms your first point.the only times this will help is when you plant clones in containers that are much too big for them.
To be honest I don't even think that's a big deal, unless you have a puddle at the bottom from something like a Hempy bucket or a flat drain pan with too much runoff in it.the only real use of perlit or lava rocks etc is as a base under the slabs or in the bottom of pots for the increased drainage capacity it gives.
the wet mush just below the root ball in coco is a no no for ideal growth.
Perhaps this is the key, i think it allows me to transplant into larger containers than normal.the only times this will help is when you plant clones in containers that are much too big for them.

when it come to flushing for harvest i have tried a few variations, but i find a big massive flush about 1 week before harvest till your return ec is really low like 0.6 and less then i turn watering times up a bit and leave it to run fresh ph corrected water through the system for the remaining time 3x a day. i find if i let the coco dry out, it defeats the object of flushing some what as the remaining salts will get concentrated as the plant absorbs the remaining water. this eds up with gray ash instead of white when you water till last day.
Perlite will improve drainage and ensure O2 comes in and CO2 goes out.
... So far I see no visible difference, besides the perlite pots drying out a bit faster.
I don't feel that I'm ever at the risk of over-watering with coco except for a 2-3 day period after a transplant into a much bigger container. Usually if I pre-veg in real small pots (2.75" - 3" square) or 16oz cups, I can virtually eliminate the risk of over-watering. Without perlite.this allows to water/feed more often with no risk of overwatering
For Mr. Carlson,
I hate the guys music but since I own a collective in Colorado (ironically not in Denver) and spend half my time in another city with incredibly-Draconian pot laws; people call me john denver. Idk if that explains enough.
