@420stoner, u need to use some kind off material that block out light and can do that fore a minimum off 2 months, alot off material breakdown or wear, when exposed to outdoor weather.

The cheepest i can get is polydress-texaleen, black plastick that farmers use to cover hay, potatoes piles with when laying out side.

That comes in big rolls 50 m by 6m or bigger and can block out light fore 1 year, u need to change every season.

@Bling it wont work u need to block the light 100 % i have seen the funnie freak plants when a beam off light hits them or they grow right into the blackout materiale, last year i had a row off powerplants where the half part off the plant grew very close to the black out materiale and some light came in from the bottom, all that row the half side off every plant was so freaky with 1 finger leafs and the other side off the plant was fully normale producing nice buds...

Hey there,
can anyone direct me to pics or links of larger automatic darkening systems?
Or just tell me how they work? Bigger ones, that is.

Hey SpanishW u need to do study off the subject, it is used in professional greenhouse gardening..

They work by strings and a special motor what pull the strings.. Not easy to build your self but if u buy a second hand 1 and build the greenhouse so it fits. Is the cheepest way..

Other wise u need a V-block style greenhouse if u want to run the new systems....

Good luck.. a greenhouse with automatik shading system is a bud producer, where u can grow alot with very littel work... Only harvest will be a major task...

I need to black out a 15'x70' greenhouse with exhaust fans and intakes and also has a ss double wall gh heater vent. I was thinking of boxing the exhaust fans and attaching round drainage pipes the kind that are corrugated and about 3 feet in diameter to the boxes, same for the intakes and pulling the blackout tarp over that.... any suggestions would be great. Thanks

Man, this is the shit.
We did a spring crop, that was more out of neccessity, moving them out of the flowering room to make more space. It worked. when done, we put clones in pots, put up a screen(stupid idea), and rocked out

We did not use automatic stuff. The first round was black plastic on the inside(14X15X6 high), run thru the ribs.
2nd round, found a big tarp that fit(15X25). Both times it was just black shit hung at the ends, super ghetto
Next year its on. Bigger gh, and , not automated, but rolled up tarp on a roller, instead of hand
730 am, 730 pm Got a cell phone but no service, just to have alarms set at 7 and 7. But it got to be habit.
It was also a time to do all of the work, and beginother stuff, so work is done by noon, mostly, and chill until 730 pm.

I meant to say that when the first light dep crop was done, we did another light dep crop. 2 crops back to back
with 2 months veg time indoors, then do one while the next crops girls are vegging for 8 or 9 weeks, hopefully one could yield nicely, with organics, maybe 20-25 gallon home made smart pots(not done that yet)...thats the plan for next yr. 48 each time, legal limit with 2 people growing for self and 3 patients each
