Looking to grow for the first time outdoors in Costa Rica. Planning on digging holes, amending the soil and start plants from seedlings. Needing help on: 1) best type of strain to plant in the moderate (never hot) fairly wet (frequent rain) Central American climate. 2) also need to know best time to plant in Central America - specifically Costa Rica, and 3) also curious about how plants know when to flower as the daylight sun is basically 12 hours year round.
I would probably grow auto flowers since the light cycle is at 12/12 approx. I really don’t know of many strains that like wet climates but I would look for one that is very resistant to mold and rot.
Not the best scenario , they will want to flower right away if not autos another thought is a water proof light to prolong veg state till they are the size you want them then go natutal 12/12 for flower time
You can push autos to stay in veg a few weeks longer by manipulating their nute regimen. Or try a super auto.
Will that be effective with their lighting situation?
That’s why autos are wonderful. They flower based on their own internal clock, rather than depending on a specific light cycle.
If the plants are within reach of electricity, you can just grow photoperiod plants and keep them from flowering by turning on a light for 15 minutes at midnight. Do that every night and they will stay in veg state for years. This is how people keep mother plants for long term.
To flower, just stop using the light. The 12 hour dark period will start them flowering immediately. The length of the dark period is the critical signal to the plant.
Could you explain this a little more plz?
Instead of switching to bloom nutes at the first sign of pistils, push veg nutes for another 2 weeks or so, then do transition nutes (50/50 veg/bloom) for a week or 2, then switch to full bloom nutes. Let me get a post from @screwauger. I wonder if I can find it before he posts it.
I gave you 4 hours @blackthumbbetty
LIFECYCLE OF AN AUTO
A 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.
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 pistils.
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.
You do get much bigger plants
Very useful information!
That’s great info & it really does push your autos to grow more.
