Auto-Flowering Classification : Indoors or Out

SGS

Hey Everyone!
I wanted to address something that is bothering me, with the vast amount of variation in True Auto-Flowering strains now, they should be Classified as to what type of AFs they are. These classes will help growers select the correct AF strain for their growing methods.

Over the last few years seen many people try to grow True Auto-Flowering strains outdoors but end up with tiny crappy dwarf plants that are almost worthless. I will try to clear up some of the confusion of which True Auto-Flowering strains should be grown outdoors and which should be grown indoors only. Maybe I will start another thread that gives a list of what Classification each strain belongs to, would love your guys help with that list!

There are 3 AF classifications due to average height, growth rate and structure of the plants:

Micro ( 0-35cm),
Dwarf ( 35-70cm),
Monster ( 70-140cm) in height.


Micro Auto-Flowering Strains should really only be grown Indoors! Due to their limited amount of slow vegetative growth, putting them outside under a shorter period of light each day, along with unstable temp and weather conditions will result in very small plants and come no where near the potential they show indoors. Micro AFs are mainly used for stealth micro grows, AF-SOG systems, or Blanket Cropping in soil beds.

Dwarf Auto-Flowering Strains classify most of the AFs on the market today, with so much variation between these types of AFs ( speed of vegetative growth, branching structure, resistance to temp and weather changes, etc...) it is hard to standardize where they should be grown. For the most part Dwarf AFs should be grown Indoors to reach their maximum potential, but some Dwarf AFs are hardy enough to be grown Outdoors with great success. Most AF breeders don't include Outdoor performance in their descriptions usually because they haven't been tested outdoors. Try to avoid growing Dwarf AF strains outdoors unless they contain outdoor performance information in the description, or they have been tested outdoors by a reliable source. With the amount of variation in branching structure of different strains, care should be taken when planning the system they will be grown in, pot size and spacing should be considered concerning the strains branching structure. Indoors look for strains with limited branching when considering a compact AF-SOG, strains with a healthy branching system require more space to utilize for maximum yields. Spacing is a major concern to AFs indoors, do a lot of research to be sure of the growth structure before committing to a growing method. If grown outdoors Dwarf AFs must be started outside, in a green house, or sun room. Starting them indoors under lights then put outside in sunlight may result in stunting as the plants take a long time to harden off from the sunlight. They also do best in containers instead of direct ground planting, select the best size of container in relation to plant size. Usually nothing smaller then 2 gallon pots with a standard of 3 gallons or more per plant outdoors.

Monster Auto-Flowering Strains
are the largest AFs to date, averaging close to 1m or more in height and width. Monster AFs utilize an extended and fast paced vegetative period before flowering, resulting in much larger plants, ( NOT to be confused with SEMI-AF STRAINS!!! ) They also seem to be more resistant to outdoor conditions and are the best AFs for outdoor yield production. This class of AFs should be started outdoors if that is where they will be finished, but they have been successfully started indoors then moved out with ok results, with that extended veg period they have time to recover from the move to outdoors and continue to veg out before flowering. They can be transplanted after sexing directly into the ground, if containers are used a minimum of 3 gallons is required, with a standard of 5 gallons or more. Monster AFs usually take longer to finish then the Micro and Dwarf Classes, so expect a few weeks longer in the garden when growing the Monster AFs.


Expect to see these classifications on SGS gear, other information will be added to each strain (when available) as well, AF-SOG spacing in soil and hydro, growth structure (branching or not) and so on. Just seems necessary. Each class can be filled with more details and so on, what you guys think?

Peace :tiphat:

Very competent classification SGS :yes:
The outdoor tips are really on spot.

Good write up. It's all about picking the right variety to suit your grow space. A little pre-planning goes a long way to help people get the outcome they want.

And the semi-autos (light sensitive) that can be total monsters (my Typhoons are noy just under 2m high) and still finish in 20 weeks outdoors. Often these are to big for indooor growing. My 2c´s.

Thanks guys, I just hope people read it so they don't continue to try and grow AFs outdoors incorrectly. Research your strains before you attempt them Outdoors, not all AFs perform well there.

Ty for the info sgs. I didn't know this so I will do a lot more reserch. Out of your strains what would performe good outdoors Ty again

Are these guidelines for when a strain is grown to its full potential? As some strains could be in two catagories..

Eg, I'm growing Fruit Salad X Pinkbud, and they are all around 25-35cm - but that is under 400w in a SOG , started in 1.4 litre pots. potted up into 6 Litre @ sex. Lighting schedule 18/6 .

So this grow they would be classified as micro, but had I grown them under 600w or started them in larger pots they would be averaging 45cm at a guess so dwarf..

Lots of variables...

I think it depends on how they all would perform under optimal conditions or otherwise we've got to standardise the minimal requirements for them. like all in 20 liter containers with organic soil under 400 watt lamp or so, something most of us could pull off.

Outdoors on full medium with cubic meters of organic soil, my Diesel Ryder males grow up to 1.85 meter tall, whereas the same genetics would not get taller then 60 cm in small containers or lousy soil.

Thanks again! I just seems needed now days to help swim your way through all the variation coming out in AFs. Hopefully more breeders will include this info on their strains.

These Classifications are used to describe the average genetic potential of each STABLE (no point if the strain clasified only produces plants in that class a % of the time) strain, grown to an acceptable healthy state. Of course people will get different results due to the different variation in their setups and the variation in the strains and stock they grow. But, stability with Classification will help growers a lot with AF selection Indoors and Out. Like I said there needs to be a list of strains made that holds true to a certain Class. Your help and experiences will be very good.

Who would want to see a AF only grow book???

I would love to see a auto book would your mix seeds be good for outdoors.if I rember right there is some crosses in there this session was a bust couldn't get out to water them.so want to do autos next year.and play around with them.is orge in any of the crosses.Ty again sgs

do you have any monster auto strains coming out? i could use a nice outdoor strain to grow in cornfields in my area.

not to throw you to much out your line of thinking but...

alot of the results does depend on your system and your level og growing skill, if you grow autos in party cups the dont expect 5oz yield per plant but if you put them in hydro its a different matter

im not sure what the average yield is on your pinkbud or secret citrus but put them in my hydro setup and ill show you what they can really do

all im saying is a lot depends on the medium you grow in as oppose to the strain itself

Skotty - Valid points, I think the purpose of the thread was aimed mainly at soil growers as it is a given that plants will excel in veg in a hydro system.

There are loads of variables like I've previously said but I think SGS was getting at not to put the smaller strains outside and expect indoor results from them. Unless you have a very Sunny climate and give them an ample amount of soil you may be dissapointed. But what works for one person doesn't work for all.

I think it is for newer or new to AF growers to have a decent guideline of what to expect.

Now I'd love to see you grow SGS's Ogre in DWC when it is released although I have a feeling from what SGS told me that it may get far too big for your tent - they are verging the limit of size for most indoor setups (tents particulaly)

cheers, mitch
