Popular Post Serpent Posted August 22, 2011 Popular Post Share Posted August 22, 2011 Serpents guide to growing autos in soil I get asked a lot of questions about growing auto’s, firstly I won’t say I’m an expert by any stretch of the imagination, but I have had some success with them, getting on average 2oz a plant, give or take, grown in a DR60 under a 250w HPS, so I thought I’d put this guide together, I should stress though it’s only from my experience and not a definitive guide, it just seems to work for me. I should also mention that for my grows I use Plant Magic Supreme Soil, Plant Magic Oldtimers Bloom and Plant Magic Bio-Silicon so this guide is based on what I’ve learnt using these products and that other nutes & mediums might react differently. Germination It’s been well documented that auto’s can have a tougher seed shell than photoperiod strains, and I’d agree with this, I’ve read stories of people rubbing them with sandpaper and all kinds of things to try and weaken them before germinating, I personally think it’s not needed, the most successful germination rate I’ve had is by following this method: Soak them in a glass of water for approx 36 hours By this time the seed might show signs of cracking Place seed in 0.5 litre pots with pre-wetted soil Put them in a propagator, if you don’t have a propagator, cover the pot with a small plastic bag or cling film, and put them in a warm, dark place, I usually use my airing cupboard Keep the pots moist, not soaking, with a high humidity After another 36 hours (give or take depending on soil, environment and strain), the seeds should now be breaking through the soil so it’s now time to get them under light. Seedlings I always start the seedlings off under 24 hour light in a microbox using CFL’s (3x 23w), after a day or so they start reaching for the light, the seed shell should also shed by itself around this time displaying its first set of cotelydon leaves, but as it was outlined earlier, they do seem to be a little bit tougher than photoperiod, so a little human interaction might be required, the method I use is to carefully, and I can’t stress carefully enough, remove it with a pair of tweezers. Feed wise at this stage should only be water, no nutes as there should be enough feed in the soil, and I usually administer it through a spray bottle carefully, I also try and keep the pots moist during the first few days under light. Potting Up At around 7-10 days, it’s time to pot your girls up to their final pots, the jury is still out whether to start autos in final pots, or pot up once established, I always use the latter method which works for me, one day though I’ll have to start them off in final pots to see how they compare, but the key is to get them into their final pots sooner rather than later, certainly no longer than 14 days as unlike photoperiod, they don’t need regular potting up during veg, I'll also add a small dose of Plant Magic Bio-Silicon at this stage, usually around 1ml per 2 litre over the next few feeds. Final Pot Size They say the bigger the better, as I grow in a DR60 (60x60x140cm) I am limited to what pot size I can use, I’ve used both round 7.5 litre and square 6.5 litre pots and to be honest, I haven’t noticed a huge difference in yield between the 2, so lately I’ve stuck with 6.5 litre as it means I can fit more plants in my tent. Light Cycle Once potted up, I’ll move the girls into my tent under a 250w HPS under a light cycle of 18 hours on and 6 hours off, there’s lots of talk whether they should be kept under 24 hour light, 20 hour on, 4 hours off, and from what I’ve read there’s isn’t a huge difference in yield, so to take the cost of electricity into consideration, I always grow mine on 18/6 which it stays on until harvest and so far I’ve no complaints. I did recently read that Big Buddha recommends in the last couple of weeks to start knocking the lights down gradually until you get to 12/12 to reproduce the natural cycle of the sun as you head towards the harvest date, although I’ve yet to try this method, if anyone has, it would be good to know what results you got. Nutes At around 21 days you should start seeing pre-flowers appearing, don’t be anxious to start the nutes at this stage as the key to feeding autos is less is most certainly more as they are well known for being light feeders. My last few grows I’ve completely bypassed Grow nutes and started on a low dose, usually 1-2ml per litre of Plant Magic Oldtimers Bloom at around the 28-30 day mark. The reason I don’t use Grow nutes is with potting up, the young plants generally don’t need extra nutes, that said, if you start them off in final pots, you may very well need to give them a little bit of Grow before they start to flower, don’t be in a rush to add them though, try and read what your plants need, if they look healthy, leave them be. Over the course of the grow, I rarely go over 3ml per Litre Bloom, I will occasionally knock it up to 4 ml, but only if I feel they need it, and quite often I’ll do alternative feed of 3ml per litre, then just plain water and around 53/54 day mark I’ll start knocking them down so the last 2-3 feeds are just plain water. Trimming Unlike photoperiod, autos don’t need as much trimming and some growers prefer not to trim them at all, I do trim the lower 3rd of the plant a little bit, but it’s mainly any dead, dying or yellow leaves as the buds develop, and I’ll also snip off some of the smaller popcorn buds which appear low down and don’t really develop into much, but this can be personal preference though as there certainly no harm in leaving them. Harvest Most breeders say autos are ready in just 60 days, now most I’ve grown can be chopped at 60 days, but to get the most out of your crop and to get a heavier stoned, it’s well worth taking them longer, my target is usually 66 days, although I have chopped earlier and later, but I use this as my benchmark, it’s also worth using a magnifying glass or jewellers loupe to check the trichs so you harvest at the optimum time for what you want. So there you have it, my guide to growing autos, like I mentioned at the beginning, this is in no way a definitive guide, it’s just what happens to work for me, but I’m always up for learning new methods and using different techniques, so all you auto growers out there, feel free to add to this thread, post pictures of the successes or disasters (I mean, we learn from our mistakes!) you’ve had, strains you’ve tried and recommend or just anything related to the love them or hate them variety of autoflowering canna. And to finish off, here’s some photos of past auto’s I’ve grown - Keep it auto Cream Caramel Auto at 66 days Cream Caramel Harvest Purple hues of the Cream Caramel Speed Devil #2 Il Diavolo harvested at 49 days Fast Bud and Speed Devils at 61 days Fast Bud harvested at 62 days 223 Link to comment
Steiner Posted August 22, 2011 Share Posted August 22, 2011 Excellent post Serpent, well done for taking the trouble of such a well-written article. And for those of you not familiar with the auto-king, Serpent grows monster autos, apparently effortlessly ... take heed! 11 Link to comment
vince noir rock n roll star Posted August 22, 2011 Share Posted August 22, 2011 nice work serpent ,i grow using the same nutes and silicon,but use a 300watt red cfl all the way through .and for the foreseeable future im going to stick with creme caramels and auto black jacks ..good high .good plants . 9 Link to comment
thisUncoliingMortal Posted August 22, 2011 Share Posted August 22, 2011 those are the sort of photos that would be good to whip out when a discussion turns to the smaller yields that can be expected drom autos compared to photoperiod strains dude.. autoSerp indeed.. 1 Link to comment
Raineh Posted August 22, 2011 Share Posted August 22, 2011 Hummm everytime i see your posts I think eek i must try those automagical things. Wonderfull collection of info thanks +1 2 Link to comment
Serpent Posted August 23, 2011 Author Share Posted August 23, 2011 Thanks everyone, glad it's been of some use and I thought it would be a nice addition to the site as there seems to be a lot more folk dabbling with auto's of late 6 Link to comment
squirrel Posted August 23, 2011 Share Posted August 23, 2011 That's very interesting, great thread. I have some Cream Caramel seeds waiting for a growroom slot, your bud has me almost drooling. :applause: The Joint Doctor strains generally need 70 days IME, are you counting from when you plant the seed, or when it pops up? So far I have a 100% record with autos germinating, by simply planting them in moist compost with no soaking or other preparation at all. I don't use a propagator, I just whack them straight under the light. I start them in 7 inch square pots, about 6.5 litres, because that's what the breeders generally recommend, and they seem to do pretty well on that. I go with 20/4, on the theory that you want to pump as much light into them as possible during their short lifespan. 6 Link to comment
Serpent Posted August 23, 2011 Author Share Posted August 23, 2011 Thanks squirrel, and I count day 1 when they've popped their little heads above the soil and I'm sad to say I've not had 100% germ rate going straight into soil, had a few none starters, hence why I now soak them and I should try going straight into final pots to compare them to potting up, maybe something to try next time. Have you got any photos of past auto's you've grown? 2 Link to comment
squirrel Posted August 23, 2011 Share Posted August 23, 2011 Mine are not as pretty as yours, I'm afraid, we had some heat issues as you can see. Plus I don't have your talent as a photographer. These are Easy Ryders and Big Devils, and a couple of Dinafem freebies, which we grew last year. We got a pretty decent harvest. We didn't weigh it, it's such a hassle and we don't really care, but my notes say we filled ten Kilner jars, two of them oversized, from ten plants. 8 Link to comment
gumpstar Posted August 23, 2011 Share Posted August 23, 2011 n theres me thinking autos were poor yeilders! not that ive tryed any but looking at this il may well give it a go. sum good work goin on here! :applause: whats the smoke like? ive never had the plesure 2 Link to comment
squirrel Posted August 23, 2011 Share Posted August 23, 2011 (edited) I rate it as good as ordinary plants. e2a The Joint Doctor strains I find quite uppy, really good get-up-and-get-organised smoke. The Big Devil is a good yielder, a decent but not spectacular smoke. The Dinafem Haze was a little small, but a cracking smoke, I'm going to grow some more of those.

gumpstar Posted August 23, 2011 Share Posted August 23, 2011 saying that i think i woz given sum autos freebies(thanks attitude) last year! thanks for the info guys keep up the good work! im off to go n have a look at my seed stash! 2 Link to comment
Skinny_Jimmy Posted August 23, 2011 Share Posted August 23, 2011 Fruit automatic that dinafem are pretty nice.. did one of there freebies from attitude a few weeks back and my god i wish i had put it in a bigger pot... lovely thread tho and very inspiring serpent, nice one dude 1 Link to comment
postdestruction Posted August 23, 2011 Share Posted August 23, 2011 I grew 8 Speed Devil #2 out in hydro system last grow and was pretty impressed although went way over the 60 day mark. Fairly new to growing mind. I got 18oz dry off them and it is really enjoyable smoke, giggly as fook! Sorry. crap pic!! 7 Link to comment
