Good morning everyone. 👍
I grew weed in my greenhouse for the first time this summer.
My biggest problem has been running out of time.
I planted 5 seeds at beginning of May. All germinated in 6 days. Plants grew well although very tall, however, flowering took it's time, beginning around middle of September. The temperatures started to drop in October and the flowering came to a standstill.
Would bringing on the seeds say a month earlier have solved this problem?
I understand that flowering is triggered by shorter daylight hours which suggests to me no matter how early I plant the seeds, nature and the seasons control when the plants decide to flower. It's been a bit of a disaster though, bad yield.
The seeds I bought were suitable for greenhouses.
Advice/thoughts appreciated.

lot of folks start there outdoor plants inside around feb,not sure of your area,think you said uk in another post,so your envorment complety oppisiste of here,but my buddies that grow around the west side of usa start there beans indoors under lights,right around easter is when they get them outdoors after hardening off the plants,main thing is keep them vegging,the days are longer around that time.
one friend has cable runners above his grow were he can slide shade cloth over the grow when needed attach to the top of poles he also has drop lights to supplement the 18 hour day if needed,over cast day got out to early or whatever,in your green house you could do the same,the light dont have to be intense like it would be inside ,but light of any kind make them veg same as a tent or what not,even a back porch light can effect your plants,the shade cloth also provide extra protection from pouring rain ,not that he gets much of that same as me but when it does it floods the cloth is a 50-50 thing.
welcome to the farm friend hope this gave you a few ideas,supplemental lighting in your green house would help a lot for coming seasons

A lot of the problem might be the strain that you are growing. Sativa strains seem to flower later than most Indica and Indica Hybrids, at least fro my experience. Sativa's also can take 12 weeks or more to flower, which makes it a poor choice for growing in northern (or southern) climates that have a cold winter. Indica strains will usually start to flower in August if started in early May ro earlier (starting indoors is fine). A Sativa started early might flower a little sooner than one that is started later when grown outdoors, but I don't think it matters too much as the photoperiod is the main trigger and it doesn't vary much.
I would recommend an Indica or Indica dominant strain, or even a possible auto if a short season is a problem. I live in the NYC area and have never been able to get a plant to finish well when outdoors... I always run out of growing season and end up with buds on my snow covered plants in November. Beware of growers claims they have ultra short flowering times... it is usually a gimmick to get more customers like yourself that have shorter growing seasons. If you start an Indica early indoors and move it out as soon as weather permits, you should have a large plant and a nice yield by October!
 
Thanks for the advice.
I'm a casual grower so starting seeds off earlier in the season is my plan. I haven't got the time or inclination to get too technical.
The plants I grew were Indica and suitable for greenhouses.
The plants grew very tall, which was another issue due to privacy, so I'm hoping to grow horizontally next year to control the height.
Thanks again.

top your plants a few times that will help..... Most everyone does alot of training.... I don't but that's just me...... I have always grown outside and I believe the sun and time does what is needed.... Now I'm trying in tents and I'm here getting Help also....

Hi. And thanks for your info.
I grew Blueberry Twist. An Indica that's suitable for greenhouses however, I have no idea it's a quick flowerer or not.
I'm in Devon, South West UK. Lots of humidity this summer which became another problem for my plants.
So I require a fast flowering Indica . ... I still have 3 Blueberry Twist seeds and planned to use these for next year. Good plant for what I need or would you advise another?

I would use the same beans , you have them.... you run them and know what to do now, go for it again, just start 6 weeks sooner or so..... start those beans in feb/mar inside with a led house light if needed........

I nipped out one of my plants to experiment but didn't think it liked it.
I'm growing Blueberry Twist again next year but am going to try growing horizontally this time. Not sure how I'm going to provide blackout conditions to trick the ladies into flowering though. I have other things in the greenhouse to consider.
I sometimes wonder if I'm over thinking this .... 🤔🤣

I think an autoflower variety might be a good choice for you, as mentioned above. Auto's don't require a photoperiod and are more predictable regarding their life cycle and budding periods. I haven't grown one myself, but I think they would be great for a case like you have. With an Auto, you can start anytime you wish and get buds when you want them. Photoperiod plants are great if you have the time and location to grow them properly. If you have time constraints, an Auto might be the answer to your problems.
