flowering indoors, latest I can move outside?

[squarepush3r]

I'm trying to do a year round type grow, but light dep seems a bit difficult (as I will be straight outdoors, and not greenhouse).

My plan is to veg and flower indoors, until about 2 weeks flowering indoors, then move outdoors. Do you think they will revert after the 2 weeks of flower if the time is not right? Such as, March - June?

Is my idea a good idea?

Your idea is a good one in my opinion square. I know a little about your plan.

1. Larger plants arent nearly as succeptable to sunburn as are smaller seedlings. Several times i have moved a 16" plant directly outdoors without any hardening off at all.

2. The flowering question is more complicated. If you are in the N lattitudes, and set the plants out before June 21, they will attempt to reveg. If you wait until early to mid july, the days are getting shorter and the plant wont try to reveg. The cut off point is approximately 14. 5 hrs of daylenth. Below that daylength, combined with ever shorter days and they will continue to flower. Above that daylenth with daylength increasing and and they will try to reveg.

Each year, i start 5 plants,(usually a 10-12 week finisher), on June 1 and grow them under 24 hrs until June 25th and then i turn the lights back to 13. 5 hrs. The plants begin to flower and 3 weeks into flower, I set them outdoors on July 15 or so and they finish up early sept without any problems at all

Once i set them out mid june and they reveged on me.

Good luck

Silverback's 60/60 Forced Flowering Approach

I had planned to try it last year with a bunch of c99 clones but I just hardened them off and planted out in early august. Didn't get to see if they immediatly flower since the deer got to them so quick.

I've seen some growers here that flower in the spring but I think they are doing light dep toward the end, but don't hold me to that. My climate is way to cold for a spring run like you're going for. I'm taking my seat I hope it works for you!

Whats up?

I always thought that if you have your plants out by the end of May to anytime in June, they would start flowering sometime in July and harvest in September, any truth to this?

no Sweetbudz, i dont think thats true. Daylength determines flowering. I plant my plants early may and my plants begin to flower buy August 1. The reason they begin to flower by August 1 is because my daylenght on that date is low enough to trigger flowering. At a higher lattitude, say 50 degrees north, that daylength doesnt come until Sept.1, and the plants wont finish until november. Thats why northern growers have to grow strains that finish fast and early. Thats what i think anyway.

Cannabis isnt a plant that grows a certain amount of time and then flowers. Until the daylenght falls below about 14 hrs, they wont flower.

Check out Silverback thread, many key facts exposed.
Other than hours of light, decreasing lenght of the day is important to push plants flowering. Thats why force flowering strategies work better after summer solstice and spring crop are always tricky to dial in. A little light dep helps a lot in spring, the easiest method is covering plants before the sunset then uncovering when the night comes. That way the covering can be a little more forgiving (you're not in full sun).
Just check your sunrise/sunset times and be consistent.

It depends on your strain.. I grow plants that start flowering in 2-4 wks after solstice. it doesnt matter whether I plant the seedlings in mid may or end of may or beginning of june they start flowering by July 5th finishing showing by July 22-25. and they are finished about mid Sept to end of sept, depending on frosts.
or go with autoflowering plants, they start 3-5wks after plant comes up out of ground no matter how much light you give them.
