What Times Should You Pull Tarp for A Light Dep?
3 Methods

By Pearl Moon

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!
