2026-27 Winter Greenhouse Grow

[Need2Know]

Most excellent little den besides being a green house. Looks like you're going for the all white Christmas lights this year rather than multi-coloured. : )

Wow, that’s really cleaned up nicely. Kind of like an outside man cave. Looks great

Finished rehabbing the greenhouse today. See pics. Will add portable electronics a day or two before grown out seedlings go into 7 gallon pots.

Seeds have arrived. Need to think through a little deeper on exactly which strains I will plant, why and how to train. Will update all this weekend.

Nice.

Hi, gang!
I am going to post a spreadsheet soon with the various features of the four strains chosen for this 12 plant winter grow experiment.
But, first, I would like some feedback from those experienced flipping photoperiod plants from veg to flower.
I am going to grow three photoperiod Blue Dream seeds in the greenhouse, no light but the sun. They will mostly grow in 10-12 hours of daylight. 50/50 c/p, 7 gallon felt pots, GH Trio plus CaliMagic, pH 5.8 to 6.2. Temps 60° to 85° F. Questions are:
1. To how many nodes should I veg them under my garage grow light before moving them into the lower light greenhouse?
2. Once placed into the greenhouse, how much flowering stretch would you expect?
3. After switch to flowering light cycle, how long do you estimate to Blue Dream harvest?

Please remember, one plant will simply grow out naturally, one will be topped and one LST'd.

Thanks for your insight!

Back again. For those interested, I have posted an image of the four plant strains that will be grown in this ex

periment.

A 6 and 8 foot auto flowers, I've got to see this, and I'm going to say 10 weeks minimal on the bd

I usually go to 4 nodes in veg on photo.
Stretch not quite double
10-11 weeks on blue dream? Never grown …
Curious to see 6 foot autos..

I will have to agree with Beeman for the Blue Dream. It's the only Photo. Two things. I was wondering how you were going to get around the veg period with the photo. You are growing the Blue Dream under a grow light through the veg cycle rather than outside start to finish. That explains it. The second thing is the auto's demand at least 18 hours of light from start to finish. I wonder if they will grow stunted with the reduced lighting of an outside grow in the winter. What was the daylight time again, 10 to 12 hours per day. Ha ha ha, we will see. Great experiment your doing.

Thanks, all, for advice on the Blue Dream photo. I am not expecting large Blue Dream photo plants.

No disrespect to Need2Know, but the winter grow produces a fine crop, a tried and proven result. It avoids the harsh, hellish summer climate. FACT: The autos do not need 18 hours of light. They are not indoors. t does add an extra 2- 3 weeks seed to harvest (documented from personal other sources).
I am not thinking I will have lots of 6' autos. The estimates on the seed selection spreadsheet were direct from the seed provider's website, not mine. For those tent growers who have never seen a 6' auto, look at the below pic. A 5' 6", untrained, Nothern Lights auto from three years ago.

 

[Need2Know]

Thanks for the reply and the info on them Auto's. 2 to 3 weeks extra time to harvest a full crop in the winter. I never knew that. I've never grown in the winter and I don't know anyone who has. That's why I'm interested in what you are doing. Carry on my friend... No negativity intended.

That’s what I love about gwe open everyone is open minded, friendly and willing to explain and experiment. This should be an interesting one.
