A 4x4 grow tent needs a scrog net that measures 48 by 48 inches. Nets sold as 4x4 ft fit the frame, and a 5x5 ft net works if you trim or tuck the extra. Mesh squares between 3.5 and 6 inches are standard, and the first net sits 8 to 12 inches above the pot when you flip to flower.
Why 48 by 48 inches is the number that matters
A tent sold as 4x4 has an exterior footprint of 48 by 48 inches. The interior runs smaller, often about 47 by 47 inches, because the corner poles and the fabric walls eat space. A net cut at 48 inches still fits, since mesh flexes and the corners pull inward.
When to Start SCROG Cannabis: Screen Height and Timing
Measure the frame at the height where the net will hang. Some tents taper near the top, and a net sized at the bottom rail comes up short at the ceiling.

Can you use a 5x5 net in a 4x4 tent?
Yes. A 5x5 net gives slack, and bungee styles with hooks pull tight against the poles. Cut the excess with scissors, or fold it behind the frame so it does not shade the canopy.
Scrog vs Sog Cannabis Yield Comparison
Loose netting that hangs into the tent causes two problems: it blocks light at the corners, and branches weave through spots you cannot reach. Trim rather than bunch.
Nets labeled 4x4 are the safer buy. Sellers measure net sizes across the outer edge, not across usable inner squares, so a 4x4 net often measures close to 50 inches with the hooks.
What mesh size should a 4x4 scrog net have?
Mesh size is the width of one square. It changes how much training work you do, not whether the net fits the tent.
- 2 inch mesh: many tie-down points, tight access for pruning, best for small plants in a sea of green.
- 3.5 to 4 inch mesh: the common pick for a 4x4. Branches stay where you put them with little weaving.
- 6 inch mesh: fewer squares, open access, good for holding heavy colas late in flower.
A 4x4 net with 6 inch squares holds about 8 squares per side, which is 64 openings. Drop to a 3.5 inch mesh and you get about 13 per side, close to 170 openings. More openings means more places to tuck a branch.
Where does the first scrog net go?
Hang the first net 8 to 12 inches above the top of the pot, or about 20 to 24 inches above the tent floor. That range lets you tuck branches during stretch without pinching stems.
Add a second net 8 to 10 inches above the first once vertical growth slows, which lands near the third week of flower for photoperiod plants. Two nets hold colas that would lean into the walls on their own.
Which scrog net type fits a 4x4 tent best?
- Bungee net with corner hooks: clips onto the poles in under a minute, stretches to fit, costs more than string.
- Nylon trellis: cheap, sold by the roll, cut to any size, needs zip ties or clips to hang.
- Rigid metal grid: keeps its shape under weight, but needs a frame and does not fold away.
- DIY PVC frame with string: you choose the mesh spacing, and you spend an afternoon building it.
For a 4x4 tent, the bungee net wins on convenience. It comes in 4x4 with 6 inch squares, and the hooks mean no tools and no knots.
How do you install a 4x4 scrog net?
- Set the four corner poles at the height you want before you attach anything.
- Hook or tie the corners first, then work toward the middle.
- Pull the net flat. A slack net lets branches push through and shift.
- Tuck growing tips under the mesh every two or three days during stretch.
- Trim threads that stick past the poles so they do not catch on sleeves or lamps.
Frequently asked questions
Is one scrog net enough for a 4x4 tent?
One net handles a short plant or a fast autoflower run. Two nets suit tall sativas, dense indica colas, and any grow where branches lean. The price of a second net is small next to a snapped stem.
How many plants fit under a 4x4 scrog net?
One to four plants fill a 4x4 with training. A single plant in a 10 gallon pot spreads across the whole screen given eight weeks of veg. Four plants in 3 gallon pots cover the same area in less time.
Will a 4x4 net fit a 4x2 or 4x8 tent?
No. A 4x4 net covers a square footprint, so a 4x2 tent needs a 4x2 net or a cut down 4x4. A 4x8 tent takes two 4x4 nets placed end to end.
Does mesh color or material matter?
White and light green threads bounce a little light back at the canopy, which is a small plus. Nylon and polyester both last several runs if you wash them between grows. Look for UV treated line when the net sits near a strong lamp for months.
Can you scrog autoflowers in a 4x4?
Yes, but time is tight. Autoflowers start flowering on their own schedule, so a 6 inch net is easier to work with than a 3.5 inch mesh. You get fewer training sessions before stretch stops.
