How we review

Every page here starts from the product itself: VIVOSUN's product pages, spec tables and growing guides. From those we pull the measurements, what is in the box and the conditions attached to each figure.

What we check

• Size first. Tent footprint, height and volume, and which tent each light, fan or dehumidifier is meant for.
• What is included. Especially in kits, where the parts list decides whether you need anything else.
• Conflicts. When two published figures disagree, we use the one VIVOSUN repeats in its feature list and leave the other out.

What we leave out

No star ratings or scores, and no claims about yields or growth speed. When a figure is VIVOSUN's rating rather than a fixed measurement, such as the tent size a dehumidifier is recommended for, the page says whose figure it is.
