How tall is the greenhouse? I hear 30 gallon bags and I'm thinking this guy is growing 20 ft tall trees.. I don't know much about Oregon weather in the fall but I do know plenty about how my greenhouse grows are in a Michigan fall if I allow vegetation up against the polycarb greenhouse panels.Hi,
I want to grow 4 Pennywise cannabis plants in my greenhouse and I could use some advice.
I live in a forest in Southern Oregon, and where the greenhouse is situated it only gets about 4 hours of direct sunlight, from about noon until 4 PM. There are tall trees that block direct sunlight in the morning and late afternoon, and to make matters worse, just about when the plants start to flower and need more light, since the sun is lower, it is blocked by more trees. I grew 4 plants a few years ago without a greenhouse or supplemental lighting and the results were pretty disappointing. Cutting down trees is not an option.
I figure that I will supplement the direct sunlight with either Spider Farmer or ViiparSpectra LED grow lights, 1 light per plant. The greenhouse is 8 feet wide by 12 feet long and has a peak polycarbonate roof. I plan on using a 30 gallon grow bag for each plant.
Does this sound like a good idea? Any advice will be greatly appreciated.
Thank you.
I do, yes. Other than that I like your idea.The greenhouse is just over 9 feet tall, side walls are 4 1/2 feet tall.
Sounds like you think that 20 gallon bags are way too big?
Here's a picture from a few weeks ago of what my greenhouse looks like as we prepare for the summer run. My seedlings are very young and are still indoors.OK, thanks for your reply.
Sounds like you got it!!Hi,

Gramps,I'm using fabric pots. I don't know if I specified that. I wouldn't use a plastic pot buried in the ground unless it looks like swiss cheese. Drainage is critical. Also its far from unheard of for roots to penetrate through these fabric pots.
There are many reasons that could have contributed to your issues with lack of light only being one of them. Over-watering is common and can occur even in plants directly in the ground. Once again, that's why I would focus on growing a plant of a size that fits your space. 4 plants kept 6' or under and not touching any glass or side-walls or even the ground should work well in your space. Use landscape weed barrier that allows water to drain through. Use border mulch and landscape stones if you desire, but that's really not necessary. I did that because my wife requested it.
Keep in mind gramps is putting his pots in the ground wich would give you about 2 more feet of headroom.OK, thanks for your reply.
I was always under the impression cloth pots won't restrict growth, As the roots grow rite thru?Mine are in 7 gallon fabric pots that are buried in the ground. It's slightly different because my roots are restricted from (easily) spreading out beyond the pot. Again, this is an attempt to control their final size. I don't want any of them over 5 ft tall to give them the room they need to stay away from the sidewalls and roof of the greenhouse. I am pursuing quality and will gladly exchange some yield for a quality finish.
Do you do the "air gap" currentlyThey do eventually grow right through, but it's still a barrier which means it takes effort. It does have an impact on the final size. How much depends on a lot of factors including how easily or how much time it takes to grow through.
Next year I might line the dirt wall with flashing material and drop the fabric pot into the hole with an air gap all around it. I will only do that if my roots weren't restricted enough. I am running out places to put the dirt I remove. LoL
It makes a lil more sense now.Not outside. Inside I use airpots on wheeled wire plant elevators so there is airflow all around them.
I expect root penetration outside. I am hoping that with the delayed start, the quick flowering of "fast" strains, and the pot adding some restriction to root growth, I will keep them out of the roof of the greenhouse. Peak is 8 ft at the top of hoop.
