90% shade cloth is all that is available in my area that I can buy local. I have a green house. I was wondering if I bought 2 shade cloth covers that are both 90%, would I get COMPLETE black out with no light coming thru by putting one cloth on top of the other ? The plants have been covered for around 2 weeks from 7-to-7 now using the black poly plastic crap that is 6 mil from Home Depot as well as I hang 3.5 mil flimsy black poly on the inside walls of the green house all the way around, THEN another 3.5 mil black poly on top of the 6 mil. I'm going to get mold issues if I don't do something very soon. The point is, the plants have already adjusted to COMPLETE black out and I'd like to stick with complete black out until the day they are cut down. I plan on running a sulfur burner anyway, but I still want to lessen the chances of mold but I also want to stick with 100% black out. Will 2 covers of shade cloth that are 90% each give me complete darkness ? It is taking me about 40 mins every evening to fidget with all that plastic and it is a major PITA.you better enter next year ... looks DOPE . goleden tarp 2015...
a little more reading for ya :

What Times Should You Pull Tarp for A Light Dep? 3 Methods
By Pearl Moon · On June 2, 2015
Days became longer than nights after the spring vernal equinox on March 21. From then until July or August is a good time to start covering your light dep setups.
Method 1: Old School Light Dep
The old school method is to close in the evening at 7 p.m. and open in the morning at 7 a.m. This method works great if you have enough ventilation during the whole grow, especially the bud cycle. Ventilation is an important component to all light deps.
Method 2: So You Can Sleep In
Another method is to close at 5 p.m., opening after dark and letting the plants wake up naturally with the sun the next morning. This method works best if you have the sun shining on your plants as soon as it comes up. Knowing the direction your land faces the sun is critical for a successful light dep.
Method 3: Faster Results
Another method is one that shortens the duration 3 to 4 weeks without any loss of size, weight or quality of product. Close at 6 p.m., open at 7 a.m. to give the plants 13 hours of darkness. A lot of ventilation is needed in this one.
How to Ventilate Light Dep Grows
When closing at night, deps can be opened up after dark and closed up at 4 a.m. before sunrise; this is for ventilation. Fans are necessary to keep the air moving to prevent mold. There are other time methods but these are tried and true with great results!
What do you think about my situation ?
