You can punch holes in it with a nail. Use tacks or a staple gun. It's fairly durable.

You're wrong about going straight into 5 gallon pots. You can do it and you will likely get results but you will get better results by repotting over time. Here is why. You do not want your plant to focus more energy underground than necessary otherwise you sacrifice canopy growth for root growth. With a large pot you end up with stagnant zones of soil that retain water and provide a breading ground for pests, harmful molds, and conditions ripe for root rot. You want the root ball surrounded by fresh, nutrient rich soil. It is important to note that the ability of peat-based mediums to buffer pH degrades over time. As the buffer degrades you may face pH swings and nutrient lockout.

See this sticky on the importance of repotting. I'm going to add it to my signature as I see this question raised quite a bit.
bigsby Reviewed by bigsby on . Indoor Grow Box Set-up Here is a quick layout on my ideal grow box. Im going to build a custom cabinet type grow box. As you can see in the photo its 3'x3'x7' and I plan to use a 4" exhaust inline duct fan with a carbon scrubber, im not sure what size intake vent hole yet, 400w HPS lighting, 2 CFL side lights, and a circulating fan for strengthing stems and in case I need to cool down the temp a bit. Any ideas on what I should add or change? Any suggestions on how many plants I can fit easily? Rating: 5
