TS: I appreciate that you aren't mad at me for disagreeing with you.
I would be far more likely to be "mad" (okay... mildly annoyed
) at someone who unthinkingly agreed with me than I would be at someone who, after thinking about it (whatever the topic happened to be), chose to disagree. Besides, it's difficult to learn new things if everyone just thinks (or "thinks"
) the same thoughts/ideas/concepts.
Advice from growers of your calibre are so much help to old timers like myself
I am certainly no expert.
I will consider another brand IF
1) It is carried in my stores
2) It is economical to use
3) Doesn't require a complicated 3-part usage schedule.
Not a fan of mail-order, I take it? That does present a challenge. Especially since I have no idea where you live exactly (nor would I wish you to divulge such personal information!), lol.
There
are acceptable one-part nutrient products, and some of them are said to be fine for cannabis and its specific needs. Or, at least, one part for the vegetative phase and one part for flowering (which I suppose would still qualify). But there really are a couple of good reasons for the existence of multi-part nutrient products. Generally, those with three parts have a grow, a bloom, and a "micro" component. The micro is added to the water first, because it contains ingredients that will mix with the other ingredients and form insoluble (IOW, will not dissolve in water) compounds otherwise. One can actually see them precipitate out of the solution in many cases. This is probably especially evident with hydroponic nutrients, because they must supply
everything that a plant needs. Having a separate grow and bloom component is helpful not only because cannabis' nutrient requirements differ from one phase to the other, but also because its needs vary somewhat from one
strain to another. Therefore, with multi-part nutrients, one need not settle for something that is "good enough" but can, instead, get the most out of each strain/plant that their amount of light and other environmental conditions allow that plant to deliver (in terms of yield, potency/effect, flavor, and aroma).
I realize that mixing nutrients can be a RPitA. I have been wondering (for I am no longer so young, myself
) if there might be a way to rig up dispensers of some sort. Not a costly automated dosing system (there are already such products - and they work great - but who wants to spend $100+ on one when that will buy a month's or more worth of groceries?), but just something that a person can use to aid them in mixing their own. Like... Well, I once worked at a place that used chemical products (NOT for growing plants, lol, as they would kill them deader than last Christmas) which came in 35-gallon and 55-gallon drums, and we had these hand pump gizmos that sat in the drums. Push down on one and get a measured amount of product. Obviously, we are not dealing with containers of that size - and those devices wouldn't give a specific enough measurement. But it would be nice if a person could "push down" one time for a young plant, twice for a medium-sized one, and three times for a "tree" (or one which was a nutrient hog). That'd be a lot easier for folks with physical limitations (/age) than having to measure out two or three different (relatively) tiny amounts. IDK, I'm just rambling.
As I previously mentioned, I no longer recommend General Hydroponics nutrients in general.
However... Several years ago, a thing called the "Lucas Formula" was popular (and I suspect that some still use it). The original recipe used two parts of the GH Flora three-part nutrient product line. That simplified things. There was a later modification specifically for coco growers that used a slightly different ratio along with a little bit of a calcium/magnesium product (or Epsom salt if one had water that was already loaded with calcium), due to the unique characteristics of coco coir when used as a medium. But the reason that I bring up both GH and the Lucas Forumla is because there is a version which uses
one part of General Hydroponics' two-part FloraNova series - simply add 8 ml per gallon of water and feed, lol. IIRC, that was said to be the easiest way to use "Lucas" - but not the cheapest. For cheapest (at the time, anyway), it was recommended to use a dry GH product called MaxiBloom (there is also a MaxiGro), which comes in 2.2-pound packages, a 16-pound bucket, and also some rather large sizes. I think the general "Lucas" recommendation for that was add 7 grams per gallon of water (as it is a dry product, some people would mix it into a cup of warm water and pour that into the rest of a gallon of water - maybe so they didn't have to shake it much, IDK), then adjust the pH as per normal.
I don't think that the Lucas Formula provided a perfect ratio of nutrients for all strains/plants - and that opinion seems to be shared by others who have since "moved on." But it was simple, easy, and many people undoubtedly still use it. And as for
cheap, lol... I just saw the 2.2-pound package advertised for $14.75 ($6.70/pound) and the 16-pound bucket for $67.85 ($4.24/pound). There are just shy of 454 grams in a pound, so mixing at 7 grams per gallon means that a little money goes a long way. However, you might have to order this product off the Internet (or email GH and ask for a sample - which might be enough for a small grow (or two)). I live in a smallish town and have seen it in the past at one of our nursery/gardening (NOT "hydroponics" - which we don't have) stores, but if you live in a very rural area this might not be the case.
BtW, I bet the strain you are growing would work in "hempies" made from 2-liter pop bottles if you were willing to "lollipop" your plants (trim off the undergrowth and extra stems, so that you are left with just one (or very few) stem(s), so that the plants could be placed much closer together). How many of those bottles do you suppose you could pack into your flowering room at one time, lol?
