Auto's life-cycle

[h=2]Another common question I see is when to switch autos from veg to bloom. Many people are under the impression that as soon as they see the first flowers it's time to switch. Perhaps a little explanation of the life cycle of autos will help to clarify this.[/h] Weeks 1 - 3. Once you've started your seeds and they break the surface of the soil, they are in their seedling stage. The first set of leaves to appear will usually single fingered, followed by a second set that may still be single fingered or perhaps 3 fingered. Once that second set appears growth will start to accelerate as the new leaves provide more photosynthesis. This process will continue, more new leaves, faster growth. Depending on the type of soil in use, mild vegetative nutes can be introduced at week 2. By week 3 most plants will start to show their sex. Males will start to produce pollen sacks and females will display pistols.

Weeks 4 - 6. The plants are now entering a pre flowering stage. During this time the plants should exhibit explosive growth, often as much as a new set of nodes and 1" vertical growth a day. This is the time when they will gain most of their vertical height. Many people make the mistake of switching from vegetative to flowering nutrients at this point, assuming that since they see flowers it must be the proper time. This is incorrect. If the switch to flowering nutes is made at this time the vertical growth will stop and the plant will put it's energy into producing buds. If you need to keep your plants small, or want them to finish earlier, they by all means switch nutes at this point. But if you want to get the most out of your plants continue feeding vegetative nutes until you see the vertical growth slow and stop. Depending on the strain that will usually be sometime during week 5 or 6.

Weeks 7 - 9. By now vertical growth has stopped and the switch to flowering nutrients has been made. The buds will start to fill out and put on weight, becoming hard and tight. Pistols will start to change from white to brown, orange, red, etc. By now the plants will also have developed a strong smell. Toward the end of this phase the large primary and smaller secondary fan leaves will begin to turn yellow. This is an indication that the plant is moving toward the end of it's life.

Weeks 10 - 11. At this time flowering nutes should be discontinued and only plain pHed water fed to flush the remaining nutrients from the soil and improve the taste. Yellowing of the fan leaves will continue as the plant draws the stored energy from them. Eventually they will die and fall off. By the time that the smaller leaves that come from out of the buds will also start to turn yellow. Then it's time to harvest.

I know that many of you are thinking that the seed bank said the plants will finish in 8-9 weeks, so why are you saying they take 10-11? The claims made by the seed banks are somewhat deceptive. If you switch to flowering nutes at week 3 or 4 the plants can finish in the times the seed banks say but they will remain small and not reach their full potential yield. Years of growing by myself and others has shown that autos do best if you follow this time line.

Of course, there will always be variations depending on the strain, the environment, nutrients, etc. This information is meant to only serve as a general guideline.

This was taken from someone who know's their auto's, it helped me alot with growing them and getting decent yeilds...

Hmm...very interesting...I have only finished one auto and really I would rather just grow small photo plants...

Auto's are great fun, and some of the strains you can can nowdays are right up there with the highest quality photo strains available.

However, not every auto seed you buy will be the same, they are still very unstable in the way of pheno's and consistancy.

i just like the fact i can grow out 2 runs of auto flowers within 14-15 weeks.

If you wanted to follow your schedule why grow autos at all why not just stick to photoperiod? Time wise I mean.

if you wanted to stretch veg cycle would you use an hps over a mh so it doesnt slow its growth while using the veg nutes.
No, MH light would be alot better , as you are just letting the plant grow to it's maximum, keep in mind this is helped by big deep pots, i use 7 gallon containers with 2 auto's under 250w MH/HPS, and leave the MH on and feeding N food right up to week 5-6.

i just got finished with an afghan kush ryeder yeilding 42g dry, and the smoke is killer!

wow thats awesome looks bomb , i just ordered big bang auto and some auto assassin and i will be using a 600w mh/hps in 7gallon containers. hope it turns out well.

1st off nice post should help many new to autos...

while I agree a lot of seed company's are just flat wrong on there finish times, there are some that will finish up by 8 weeks and cant say it has anything to do with nutes seeing as all mine are ever given is water because I use subcools supersoil, with a 20/4 light schedule all the way through they finish in less then 60 days... by 11 weeks mine would be dead on the stalks...

doin my first auto grow auto assasin keeping indoors for seedling stage under 65watt cfl 16hours n growth seems way to slow at two weeks from germination and only on second node my bbagseed photos are more then twice the size under a few 23watt cfls

yea im on my 2nd set of white widows with the first set finishing in 62 days from seed under cfl's 24/0. Yielded 153g (dry) from 3 plants. Best smoke ive ever had.

Were 7 gal containers overkill for your autos. I asked around and ppl say a 2 gal is fine.

That was weird, went to go post and saw my avatar there and though "I don't remember posting here" haha.

Anyway, I agree with what the OP is saying. Personally, I only grow autos outdoors, but I've never seen one finish from seed in under 11 weeks.

Who is this imposter! Haha

Truth be told I should actually have an avatar of his attorney know as doctor gonzo, Who is actually Oscar zeta Acosta in real life. Well if you can find a good pic I'll trade you mine.

42 dry seems a bit much for your typical auto, but then again I've never done AKR. I think I might have to do that next once my stuff is finished if you think it's worth a go. Though I'm still waiting to see how the lowryder2, doctor feelgood, easyryder and snowryder turn out. My money's on the snowryder but I might get surprised by one of them?

So far with what i have tried the AKR is the closest to a top photo period strain by far. i just finished 2 of them one with small skinny airy buds and the other is pictured already yeilding a fair amount.

Come to think of it , the roadrunner strain was great aswell, while i was trimming i noticed this burst calyx , dripping with sticky resin..
