Best 3X3 Grow Tent Review

Introduction To 3X3 Grow Tent

Choosing a grow tent for your plants can have a great impact on your future yield: if it’s too small you’ll be confronted with climatic issues and excessive power bills, if it’s too big on the other hand you might loose some light reflection and won’t be able to harvest as much as you would in adapted conditions.

Beginners are often advised to start with a 400 W HID lamp using HPS and MH bulbs, as it’s a great compromise between the cost and the ability to produce enough for self consumption.

Why Would You Choose 3X3 Grow Tent?

  • You want to grow cannabis indoors and with the ability to control all the environmental factors.

  • You want to have a small harvest of marijuana plants.

  • You are a beginner who is starting out with the first ever harvest done by yourself.

A 3×3 grow tent kit has the ideal surface for that kind of lamp, providing the best efficiency through light coverage, maximum reflection, and easy climate control ensuring proper growth conditions.

If you plan on using a 600 W HID lamp or greater, I strongly advise you to go for a 4 x 4 tent unless you have a taste for heat related issues and power waste!

High cost differences are to be expected when browsing for grow tents as overall quality and features can greatly differ, to help you make up your mind we’re going to review 3 of them: the gorilla grow tent 3×3, a Milliard one and an Apollo Horticulture grow tent.
