What to do next with Feminized Plants, Force Flower?

-Greenhouse grow-

Hey guys, These plants in the picture are currently 108 days old, i do not know if i should look at force flowering, or letting it naturally flower, Sept 26; is when 12/12 begins, so there is still another month + of growing to do. My original plan was to let them flower naturally and use a paraffin heater should the temperature drop outside, but i'm wary i may be leaving them too long. I planted them from seed back on April 22nd of this year.

It's also the first time I've seen yellow/dead leaves in the middle for a good while now and only recently just transplanted them to a new pot. They have also been topped once and was hoping to keep it topped once.

Any feedback would be great, I'm hoping i can leave them to flower naturally giving me more time to tend to my auto's, as this is my first grow on both. Thanks again.

Is the temp going to be an issue? Are they 8week strains? If they're 11 week strains then you might want too consider some light deprivation imo. It might be feasible to start deprivation now since the light hours diminish as well as intensity that way you get a better yield. Maybe this will help you decide.

Oh my, I just signed up to this forum and I could have written your exact post! I only have one plant (out of 12 seeds!!) that I started in April and I’m waiting not-so-patiently for it to flower, just a tiny one so I know I’m on the right track. Anyway, just writing to say I’m waiting for 12/12 too and it seems to be taking FOREVER!!

I don't think the temp will be much of an issue, i just don't trust the English weather, however so far it's been good, and the greenhouse is small i was hoping a paraffin heater should do the trick. It seems like force flowering could increase the yields, i may look into getting some tent's or moving them to a different location every day. again thank you for the help, i found that page to be informative, but still unsure on what to do.

Flowering Time: 7-9 Weeks with this strain.

Are the yellow leaves just a natural progression with the plant? It's been a while since i seen yellow, and only just recently transplanted.

Ah good!! i have been struggling to think what to write in google to help me out with this. You signed up to the right forum. I'd happily wait for 12/12 too, but at the same time i wonder if i should just force flower.

Guest. Yea i think im going to go for Natural light deprivation, and look at getting a paraffin heater for the greenhouse should the weather continue as it is. I will transplant just before it hits 12/12 (i believe around Sept 26th). With 7-9 week strain it looks like it's going to be a late November, early December harvest. Which was another thing i was worried about, but a heater should help me with that (i hope)

[el12341234]

Thank you man, I shall try my best, I may be back for my help when harvesting time is upon me

Just an FYI for those who don't speak the King's English, a paraffin heater is a kerosene heater - I think I spend half my time googling words when reading on this site.

The yellowing is generally one of three things,

Lack of light (Isnt an issue being outdoors)
Lack of nitrogen
Old leaves (Generally happens late in flower as it begins to die off)

To me a few leaves here and there on the lower part of the plant isnt a big deal. If it gets worse it is probably nitrogen. If it stays the same, its just old leaves.

If you do decide to wait for them to flower naturally, I would be really tempted to put them in the ground in a big pit of good soil, depending on drainage and how hard it is to dig there. Or possibly just some bigger pots, or grow bags, or even a good raised bed.
How tall is your house? Might be enough room to just go on top of the soil if it's tall enough. You could definitely grow those girls out BIG this summer, with a large harvest, especially with some nice fresh soil, and stuff like earth worm castings and bat guano.

You might not want that though, especially if smell is going to be an issue, they could get potent as 8' plants!
Would be a difficult transplant.
You could always just cover your whole house with a piece of black plastic, as long as it won't attract attention to your grow.

Ok i shall keep an eye on them, thanks for the feedback hopefully it's just old leaves.

Unfortunately my greenhouse floor is concrete however i could transplant to grow bags right before 12/12 begins or i do have bigger pots they can go in, it was difficult to transplant them into the pot's there in now but surely can be done on the next transplant. Luckily where i live i have no immediate neighbors, so smell or appearance isn't a issue. As long as i have the all clear to go naturally with it and a paraffin heater should i need it, i think i'll stick to natural light. Thanks again for the feedback peeps.

Bummer about the floor, but I'm sure you can pull it off hight wise, especially if you do some plant training. If you were to flower early, those pots would be fine, if you go to the end, I am thinking more space could give you a gig yield.
I agree that your plants look kinda hungry, and would love a good feed.
Make sure to check under and on all those lower leaves real close, just to make sure you don't have a bug problem to. I like to remove those old yellow leaves, to limit habitat for pests and mold. On a big plant in my greenhouse, I like to clean out everything in side the bottom middle of the plant, so that all my leaves and bud sites are out along the edges and tops, where they can get plenty of light and breeze. It helps to prevent the bud rot, which can decimate your crop. Nothing sucks like having to throw out a half pound of great bud, like I did last fall, well, I do know growers that have tossed pounds.

Anyway, don't let it happen to you, buddy!! Make sure you have a good fan system in there for flowering, make sure there is a nice breeze moving in, over, and around your girls to. Keep your humidity in check, and have some air exchange, all makes a big difference, and can double how much you get to keep for you.

GreenhouseEffect Great advice, i shall look at removing the yellow leaves tomorrow and possibly cleaning up the lower bottom mid. I will also give them a nice feed again. Yeah i'm going to leave it till the end so 1 last transplant should be in place. The only thing im struggling with is the Fan System as of now, the greenhouse is pretty far away from any electrical supply, and i've looked on amazon for battery powered ones but they only seem to be USB rechargeable ones. I've read about 20-25 degrees C. is the best temp for them and 60% humidity. This seems like the biggest struggle trying to get good airflow + comfortable temp whilst keeping the humidity. If anyone has a good idea for a fan system that does not rely on electric i'd love to see it. Again thanks alot for the guidance and advice. Much appreciated.

No worries. You will find that folks hear are pretty helpful, definitely post if you have questions or problems, somebody just about always knows what to do about it, and had the same thing before.

Closer to 50% humidity is actually better during flowering, and if your night time temps happen to drop down to about 50 F, that won't heart them, might even make the colors a little better, if the strain is apt to change color during flower.
The best humidity control I have found so far, in a large area such as a greenhouse, is to add a little heat at night, since the higher the temp, the lower the humidity tends to be, in any given air mass. The cooler the temp, humidity tends to rise.
When It's hot and humid, an air conditioner tends to work best. You can buy dehumidifiers, but the size you need for a large space, can get real expensive.

Fans can be a tough one, without access to wired in 110 or 120. Best thing is probably fans that run off of 12 Volt, least that's the low voltage size in this country. Basically something that can run off of a large truck battery, or Golf cart battery.
Possible you might find something that works in the world of R.V.'s and boats, just will be hard to find anything very big.
I'd say just do the best you can, the better you can provide a little breeze, the easier and more successful your grow becomes.
