Sorry for the delayed replies and I hope everyone had a great 4th of July!
Good discussions while I was gone!
Good discussions while I was gone!
I'm not aware of peer reviewed studies other than those done by me and numerous other growers - it works!Thanks Krip! I guess what I was asking for was a peer-reviewed reference explaining why only the first and second node stems would be considered main colas. If I keep the third and fourth nodes instead, as in quadlining, I’m puzzled why the resulting four stems wouldn’t be main colas?
I'm 420% sure you can find inexpensive fertilizers out there, but to use the same ratio (i.e. 10-10-10) all the way through the growth cycle for cannabis just doesn't account for the changing needs of the plant. IMHO, if there's enough Nitrogen for veg, there's probably too much Nitrogen for flower. Most nutes for cannabis are two or three part and the GeoFlora pricing compares favorably to other good nutrient lines. Then again, until a couple of years ago, I was using AN, so I'm used to paying some HIGH prices! Also, I'm not sure how long it takes you to feed your plants or how you value your time, but in 16 weeks, you would be feeding 48 times with your current nutes and with GeoFlora, you would be feeding only 8 times.Thank you, Mr. Krip. What threw me was that ounces can be used to measure both volume and weight and the only time they are interchangeable is with a substance with the same density (weight to volume ratio) identical to water but I see when they convert from ounces to cups they say it is only approximated so apparently the density of their product is close enough to water that they use ounce for both weight and density interchangeably.

Using your calculations for 16 weeks assuming an eight-week veg and eight week flower period that works out to $24 for one plant in a 10-gallon pot.
With the single part chemical fertilizer I am using I bought 9.9 kg or 9900 g for $119.29. Assuming I feed my 10-gallon pot 6 g times 2 gallons three times per week for 16 weeks during the life of my plant I would use 216 g. That is based on the assumption I would give maximum doses throughout its entire life so this is considerably larger than the actual amount for simplicity of calculation. Dividing the 9.9 kg by the 216 g each plant would take determines my 9.9 kg bag could fertilize 49 plants and dividing the initial cost of $119.29 by the 45.83 plants it can grow means my chemical fertilizer costs me $2.60 per plant in a 10-gallon pot over its life.
$24 divided by $2.60 means that going organic would cost conservatively 9.2 times as much as using chemical fertilizers per plant. Not saying the cost is prohibitive this is just the reality in dollars and cents between organic and chemical. Now I am starting to understand why the organic strawberries at the grocery store cost so much.
Yes! With quadlining, there's a lot of extra time spent on LST training the plant horizonally. With UBT, it's just a method of topping.I think this is more clear if you consider that in the Uncle Ben system, (the rules of thumb quoted,) the auxins are redistributed based on a single event. A single event at the third or fourth node will usually create 2 main colas.
Quadlining is a longer term method where you find yourself balancing and rebalancing the branching growth (auxin redistribution) by multiple training decisions made every few days, rather than a single event.
I do agree it is more but you are comparing it to one of the cheapest chemical fertilizers on the market right now though. If you look at the cost of what some of the other chemical and liquid fertilizers are with their various bottles, the cost could be more on par.
What drew me to it is being able to grow organic with a 1-part (in my eyes since you only use one at a time and never both) fertilizer, plus only dosing every two weeks vs mixing almost daily with the chemical fertilizer the both of us are using. That extra cost may just be the cost of going the KISS organic way vs the easy chemical way. Now as far as results, that’s what I’m here for (no pressure @Mr. Krip).
This method is primarily for seedlings since you need to have opposing nodes. When I UBT, I'm really taking my first clone. Usually, that first clone will also have opposing nodes and can also be UBT'd. By the time you're ready to clone again, the plant will be more mature and many times will then be producing staggering nodes which don't lend themself to a 4-cola UBT. As Brother @Radogast points out, you want enough roots to sustain four colas instead of the one you just removed, so letting it grow out a little before the UBT helps.So less traumatic - makes sense! I guess what turned me off on UBT is that I heard that you grow to node 5 (or 6?) and then top above 2 - it just seemed like a waste of growth time and energy. But I get that a more mature plant, and a single traumatic event, could lead to less impact going forward.
There is very little time lost with UBT, the plant just gets a few nodes shorter, but growth rate doesn't stall, at all.Cutting off a larger mass of more vigorus growth, leaving roots that generate more total growth energy, forces the growth down into 4 buds (modes 1 & 2) rather than into 2 buds (node 2 only).
I'm not saying I know it to be worth the time to replace those 3 nodes of growth, but I suspect it is equal or less time consuming than quadlining with leaf stripping
It might be worth the time if you planted the cut off growth into a new pot of soil as a single clone. It would be fun to experiment with a few clones and compare results.
I agree with everything you said Phantom and I certainly wasn't trying to dissuade anyone from going the Geoflora route; I was just curious about the price and posted my findings but like you I have not drawn any conclusions yet myself and agree with all your positives about it and how well it performs is really the determining factor.
Because of this thread, I did a little reading on organic versus chemical fertilizers and apparently, as I posted before somewhere previously, fruits and vegetables are more nutritious with organics so to me it just makes sense that cannabis plants raised organically would have a richer cannabinoid, terpenes, etc content so for that reason alone organics makes a lot of sense to me and has me very intrigued also how this grow goes. The more I read and think about it and hear people's opinions the more appealing it seems.
That's the "apical dominance" which makes the main stem always more dominant than the side stems so the plant tries to put all it's growth energy to the highest point. When we top, LST, or supercrop, we're forcing the apical dominance to other parts of the plant.after this discussion I now realize why I have not had any stellar grows this last year... none of my product turned out to be exceptional. It was good... but not what I expect to grow. I knew I was making a fundamental mistake somewhere, and now, thanks to Amy, I can clearly see what I have been doing wrong. It has always bugged me why on my plants lately, I always get 1 branch that rises to the top of the canopy and becomes dominant and always, each plant in the room has one branch doing this while the rest maintain a fairly even canopy below those branches. I have been priding myself on my multiple topping method that creates huge bushes with 32+ buds... and as it turns out, all but one was secondary. I have been shooting myself in the foot all along. I am going back to Uncle Bens method with no more topping after that, and thanks to another discussion with Filipe, if I have to save vertical space I will supercrop after that, doing all I can to preserve the 4 primary kolas. It sometimes amazes me how well I have done over the years, when I can still make profoundly basic mistakes such as this. Live and learn as they say... each grow will get better and better.
Oh yeah I totally agree with you, it’s like buying organic vs not at the grocery store, expect to pay more for something that is better in overall quality, from what I’ve been told. I’m trying to get some stuff set up to run clones and compare the two as far as finished product weight and overall taste. See if there really is a difference and if it’s worth changing over too. I’ll still keep running my liquid chemical fertilizers because of my rdwc but as far as doing runs of auto or clone SOGs in between my hydro runs, I may really lean towards using Geo for it.
