ColoradoJay and his 20x40 Greenhouse

[ColoradoJay]

Been doing research on this site forever and have found lots of great knowledge. Decided to ask what would you do with the space I have.

Outdoor bloom area
20x40 hoophouse with 14ft peak.
200 amp service
8000w HPS DE in umbrella hoods bare bulb
Propane heat with inflated double layer plastic

Indoor veg area
14x12 with 8ft ceiling
8 8 bulb T5s
Co2 generator
A/C and Space Heater in room for temp control

Strains: KropKing White Cookies and Dark Angel
48 in veg and 48 in flower


What system would you use and why?

Considering pure coco with 30 percent perlite in 5 gal pots. Canna Coco A & B with a few additives.

Seed are in. Have to recommend Crop King Seeds for excellence. Fast delivery and funny as hell packing.
Can't wait to pop these

nice greenhouse! does it snow where you are?

 

[ColoradoJay]

Thanks. And yes it snows. Looking forward to the challenge honestly. I'm at about 7500" ft elevation so winters are no joke. With the propane heater and a backup generator thinking I will be fine

[who dat is]

Subbed as fuck

Subbed as fuck

Thanks for stopping by. Will try to keep things posted. Finishing up my veg room currently. Plan of popping the beans this weekend.

Also thinking about spending a little more and adding 4 600w MH in cool tubes to the veg room.

i cant think of a worse choice for reflector for greenhouse growing, blocking out a lot of your natural lgiht. other than that looks like a great start

That would be true if not for the type of plastic I have on the greenhouse. It's a diffused lighting plastic. When the sun strikes it instead of just passing through it splits the beam and scatters the light very evenly. I have smaller reflectors(wings) that I will be using in the summer, these are my winter hoods. In the winter the sun is my supplemental lighting and the Hps are my primary. Plus the even light spread I get off of these is great. Will have to take some pictures to show but honestly the way the light is distributed even lights of there are no shadows in my greenhouse

*lights are off

Decided to show what I was trying to explain about my greenhouse plastic be different.

• 4 year, 6 mil greenhouse film

• High light transmission

• Excellent thermic properties

• Effective light diffusion

Solar-Ice is a four-year film that will lower greenhouse temperatures in the daytime heat. Solar-
Ice is the first highly diffusing greenhouse film that improves growing conditions by using controlled diffusion to influence the light reaching the plant. It is designed to make more light available to plants by increasing the amount of diffused light to close to the maximum, while reducing short wave infra-red radiation and enhancing useful light in the PAR range. This four-year, 6 mil film is the ideal choice as an outside layer, and the perfect partner with GT IR/AC on the interior

This leads to healthy, bushy plants while reducing greenhouse temperatures. In addition, there is less risk of plants scorching while achieving an optimum rate of photosynthesis. Solar-Ice creates higher yields and stronger-than-normal root systems, making it a excellent choice for ornamental plants, nursery stock and tomatoes.

Greenhouse owners have long contended with the loss of heat from greenhouses during the night and at times of cool weather. That is why high level of thermicity of Solar-Ice is so important. Research conducted in Europe shows that, in greenhouses covered with Solar-Ice,
the total solar heat load was reduced by over 20%, without any significant decrease in PAR light.
Your workers and customers will enjoy this more comfortable environment and you can expect this will be reflected in productivity, too.

Just a small update.

Ladies are popping their heads up

 

[ColoradoJay]

And the veg room getting finished up just in time

 

[ColoradoJay]

Give it up to Crop King Seeds for standing behind their product

Give it up to Crop King Seeds for standing behind their product

Have to say thanks to Crop King Seeds.

Had 30 White Cookies and 30 Dark Angel

Got 24 good sprouted ladies from the White Cookies with a possibility of maybe 2 or 3 more still popping up.

The Dark Angel however only germinated 2 seeds and so far none have shown their faces......

I contacted the company, went over my germination process, and the results.

And they are sending out replacements!!!!! Great Company can't wait to try their other strains

Weighing my options on heating this winter.

Option 1
Ventless 30k BTU blue flame heater possibly x2

+Easy installation
+Works when power is off
+Low cost

-not sure if they will work at 7k elevation

Option 2
Modline Hot Dawg 50k

+ Definitely would keep things warm

-not sure where to install in the greenhouse
-must be vented
-cost is higher than all other options

Option 3
Radiant tube heater 50k btu

+Easy installation
+Very good heat even spread with 30ft tube
+Most fuel efficient

-double the cost of cheapest option
-needs power to operate


Which would you pick and why?

Is your GH load bearing capacity been tested? I had a hoop collapse on me during a snow storm..

Looks good man, yea those hoods could be smaller. Can't help you with the heater question as my experience with gh's is limited to the ghetto rig PVC builds I learned in the backwoods of the triangle. Somebody will chime in though

 

[Dankwolf]

that greenhouse look great . cant wait to see how it works out .

 

[ColoradoJay]

As far as the snow load. The hoophouse has a steel frame. 2.5in Poles driven 24in into the ground are their anchors. Will have double layer inflated poly. Has vertical supports that will be installed inside at 8ft intervals. Copying a greenhouse that's in alma at 10k so hopefully things will go well

 

[ColoradoJay]

He has a boiler though, I don't have the funds for that

 

[theJointedOne]

Cool

Sorry I haven't updated for a while it's been a busy time getting ready.

Ended up getting a bunch Indica dominant Maui plants from my buddy. They are ready to be put into flower at about 3 foot tall now. Going to give them another week of veg while I finish the winter prep on the greenhouse.

So on to the greenhouse. Got it wrapped and inflated with a second layer of plastic. That helped a lot with the cold. Added 12 black poly barrels filled with water for some mass heat. I'm currently installing a 30000 BTU infrared propane heater that will be directed at those barrels. I also have two 3000 watt dr. Greenhouse infrared heaters just in case it gets super cold.

Anyway that's my update so far will try to get some pics in a week or so.
