creating 12/12 in my greenhouse now - Growing in Greenhouses - International Cannagraphic Magazine Forums

im going to experiment with 2 plants inside my greenhouse
gonna cover them with a black garbage bag at night and not uncover until they have at least 12 hours of dark
i wonder why i didnt try this earlier.............
it just seems like a nice way to grow without paying for light.....
if this works i could be doing it with small bushy plants the whole time while my big monster ladies are vegging......
i need to find a way/s to really utilize this greenhouse......one massive grow is great but i could be also adding 2 small grows also

You should put the bags over your plants only until its dark outside. Depending on climate you could be asking for a mold problem. When i did this the sun was rising sometime after 5:30am so i bagged my plants( and had a refrigerator box for one) and took the bag off around 9:30pm every night to let them breathe and everything went well. a friend on the other hand, bagged his 5 plants every night at 7 pm and unbagged them at 7 am. bud hairs were burnt, bud was airy and lots was lost rot.....

Just order up some panda film and construct a box frame with 2x4 wood. They do need to breath at night. From my experience with putting plants in cabinets, while my grow boxes were down for renovation, you need air blowing over them constantly when they are confined like that...

I just had an idea of how to give my clones CO2...(nano cloner I'll slow pop a bicycle CO2 canister and toss it in under the plexiglass lid, sealed with Press-n-Seal...oh hell, I should use Press-n-Seal alone and put the video on YouTube)

I did take a video of the "CO2 grenade" method from my camera which was inside my small growbox. That was back when I grew LR2.

So tack up one or two walls with panda film black on inside of wall to make light trapps. Use some kind of fan.

And, do you have dehumidifier/ac for the greenhouse? Some climates (arid West) don't need to bother with that.

was thinking about constructing a box out of the panda film using pvc pipe since it wont be bothered by moisture
im just doing 1 plant right now but it could really work next time around
double grow out of the greenhouse

I like tp shaped plant covers . I live where it snows and a box shape will fail under snow or rain . Just a thought
