SenorTashi Posted November 8, 2022 Share Posted November 8, 2022 (edited) I've got various seeds on the way from the US and I'm not sure what the sativa/indica ratio is. I bought a couple of clones 2 weeks ago and then realized I had to go away for a week so I planted them in the garden and 10 days later they were in flower. Somebody posted on here that they plant out when the girls are 2 foot high. I've got a couple of lights which I'm using successfully to boost the daylight hours on some more clones right now. Just curious to hear about anyone else's experiences. Edited November 8, 2022 by SenorTashi Link to comment Share on other sites More sharing options...

Popular Post oldscool Posted November 9, 2022 Popular Post Share Posted November 9, 2022 Good question. Sativa grows naturally in 12/12, after all sativas are tropical landraces and they evolved for tropical climates with 12/12 light. The "flip" to 12/12 from 18/6 (or 20/4 etc) is merely for tent growers growing hybrids to mimic the seasonal change in the more northerly latitudes of Europe and North America. It's not necessary for sativas. Tent growers usually chose not to grow pure sativas because some can grow to 5 metres! Thai sativa grows year round here. Many growers like to harvest before the rainy season simply to avoid heavy rain damage, but it's not necessary. So the answer to your question really depends on how dominant is the sativa in the breed you're growing. But I wouldn't worry about it too much. Non sativas and autos will grow in 12/12, it's just not optimal for them. 2 1 Link to comment Share on other sites More sharing options...

oldscool Posted November 9, 2022 Share Posted November 9, 2022 Another good question Marcus. And I've been curious about it for a long time too. But I'm not sure anyone has the definitive answer to it, certainly I've never seen a definitive answer. My guess is that it's mainly the time factor for Thai sativa grown outdoor in Thailand, as there is no significant difference to the hours of daylight throughout the year. Maybe it's also something to do with the amount of direct sunlight, because in a natural outdoor grow some plants will be in more or less shade. Ruderalis landraces are from Eastern Europe and Russia so they must be affected by light change I guess, to a much greater extent than sativas or indicas. They are much smaller with no significant THC and I believe they were cross-bred with sativas (and indicas) to (1) allow sativa and indica to be grown outdoor in the northern latitudes of Europe and North America and (2) to make smaller breeds for indoor grows. Indica landraces are from slightly further north than sativas - Afghanistan and Pakistan for example - so they are naturally adapted to some limited extent a seasonal light change. I'm happy to be corrected on the above if someone has a definitive explanation. 2 Link to comment Share on other sites More sharing options...

Popular Post shdmn Posted November 9, 2022 Popular Post Share Posted November 9, 2022 (edited) There are autoflower strains that will flower after about 3-4 months regardless of light. I know someone growing one on their balcony right now and it's doing quite well. Should start flowering pretty soon. Just look for anyone selling "autoflower" seeds or seedlings.

They were crossed with the other varieties to create autos, which are normally ready to harvest after 70 days (if grown outside in Europe) I'm just about to germinate 9 autos. I grew autos for years in France and the least I ever harvested from 1 plant was 10g dried bud but even that is worth doing imo Edited November 9, 2022 by SenorTashi 1 1 Link to comment Share on other sites More sharing options...

I'm not sure how my strains will grow but I'm going to give it a try. I used to grow sativa seeds in France which I had collected from all over Asia. It was very frustrating though because they would get huge but then flower too late and just end up getting frost damage. After a few years of trying, I finally harvested some F2 sativa crosses in July, without using a grow room or lights 3 Link to comment Share on other sites More sharing options...

Indoors thats a decent savings on electric as well. I've thrown autos in a 12/12 flowering room just cause there was extra space and they seemed to do fine, but were smaller. So with their adaptability they should do fine outdoors here and never worry about timing or season. Seed to bag in 10-14 weeks.

oldscool Posted November 23, 2022 Share Posted November 23, 2022 The key to outdoor growing in Thailand is to choose the most suitable strains – naturally these are Thai sativas. Other tropical sativas would be more successful here than indicas or hybrids, but only Thai sativas are uniquely adapted to the Thai climate. Not only that, but Thai sativa seeds are very easy to come by. At the moment I’ve got about 50 marijuana plants in my garden, 45 are Thai sativas (5 different strains) and the other 5 are autos and hybrids. Needless to say the autos aren’t thriving on 12/12 light, but the green crack (sativa/indica hybrid) is doing very well at the moment, though I suspect that bud rot could become a factor later. About methods of growing. One of my favourite outdoor master growers on youtube has some excellent advice about increasing yield per plant – in his US state he is limited to 6 plants - and his results for hybrids are phenomenal. However, I’m not sure his techniques would be necessary or applicable to Thailand because (1) we’re not limited to 6 plants and (2) Thais sativa is perfectly adapted to growing outdoors here anyway. His techniques are also extremely labour-intensive and I just don’t have the time for that for 50 plants. Out of my 45 Thai sativas about half will turn out to be male, but this will still give me a far greater yield than would be possible in a tent in a condo or spare room over the same period of time. And zero electricity bills, no expensive or time-consuming nutrient regime, and generally far less hassle than tents. And as 1 or 2 of the very experienced users here have mentioned, male plants can easily be brewed into an effective tea. My method, which is still evolving, is simple: 1. germinate the seeds in soil in a very small plastic cup (from Tesco by the dozen). 2. transplant the seedlings to a larger plastic cup (Amazon coffee cups are the perfect size). I perforate both types of cup with a hot metal skewer so that the water can drain easily. Clear plastic cups are good at this stage because you can monitor the root growth easily. I water from the top, using the flood method that I borrowed from the master grower above: flood the soil with water , then let the soil dry completely - takes 1 or 2 days in this climate depending on the root size – apparently this is optimal for root development. 3. transplant the plants either to large final pots or directly into the garden. I also have a simple shade mechanism for the seedlings – for the rain, not the sun – which I can put up in less than a minute. Have a good day all. 1 1 Link to comment Share on other sites More sharing options...
Pinot Posted November 23, 2022 Share Posted November 23, 2022 My 1st outside crop of 20 plants still has not flowered after 4 months. I did cut the main stalk back at 3 months but most of the entire crop is 12 feet tall! I should have been cutting them back all through the growth process but didn't know better. I think they're about to flower but I thought that two months ago. No choice at this point than to let nature take it's course. It's a learning thing. I've got seedlings of auto-bloom for the the next crop. Link to comment Share on other sites More sharing options...

"time-consuming nutrient regime"... you dont give your plants any nutrients at all? just bad tap water or rain water? do you at very least ph the water? what kind of buds do you expect from a plant that never receives any nutrients? 2 1 Link to comment Share on other sites More sharing options...
oldscool Posted November 25, 2022 Share Posted November 25, 2022 I’m reluctant to take this thread further off topic, but in answer to the previous questioner and for the correction of some of the numerous misunderstandings about growing outdoor landraces in their natural environment – ie Thai landraces in Thailand : 1. I can grow Thai sativas outdoors year round in Thailand: they are natural 12/12 species perfectly adapted to Thailand’s year round 12/12. 2. The claim that outdoor grown buds are mediocre is strange. When I and many others here started smoking, there was only outdoor grown natural landrace marijuana, and all indoor hybrids and runts since then have been bred from those original outdoor landraces for the European and Nth American markets, mainly because Europe and Nth America have the wrong climates for natural marijuana, but also for the tent growers who are space-constrained (plus ruderalis for the real indoor runts). 3. Thai stick is unsurpassed. And the very same original Thai stick landraces are still grown in Thailand, as I have described in some detail in another thread. 4. Artifical nutrients are completely unnecessary today for natural strains, just as they have been for thousands of years. I can’t comment on whether they’re necessary for tent-growers growing artificial strains. But my guess is that the European and North American indoor cannabis industries has a vested interest in controlling seeds, nutrients, lighting, cooling, tents, fanning, and all the other things that are unnecessary for natural landraces grown in their natural enviroment. After all, there are no naturally occurring European or Nth American strains of marijuana other than the non-psychotropic ruderalis runts used to breed indoor strains. 5. Ph-ing the water or soil is another time consuming activity that artificial indoor growers seem to spend time and money on. But the evidence of thousands of years says this is not necessary for landraces grown in their native environment – eg Thai sativas in Thailand. Clearly some soils are better than others, but finding good soil here is not difficult. In rural Thailand, the water irrigation system is extensive, as you'd expect in a country where 35-40% of people work in agriculture. (No, I don't use tap water.) My soil and water are regulary tested by the Thai Ministry of Agriculture, as are all organic farms. Anyone can apply for such tests. 6. There are numerous organic methods of pest control and fertilization, and they’re in use by the many organic farms here in Thailand, not just cannabis farms. As for yield: https://m.facebook.com/story.php?story_fbid=pfbid0sT7au8zQAdzLC7dPyULf1BkKkCvSK91TwDm1yPBv1HFRo7dDwKUDF56PmJ8yBZDbl&id=100083200937492&eav=AfZlLa6j6tR94ufFqos2E4FprqJ8g0t8GjcJuVdBNtBqcoUmT7ztri3W_ezV9X4N5tI&m_entstream_source=feed_mobile&paipv=0 (hope the link works for you, some people seem to be having difficulty with the FB links). In summary, I have 10s or 100s of thousands of years of nature on my side of the debate, and you have 3 or 4 decades of capitalism and big business on yours. Have a nice day. 2 Link to comment Share on other sites More sharing options...
