The Budbox Pro XL+ grow tents have a 150cm X 150cm footprint, they are available in 2 different heights with either the premium Pro-White interior or the slightly cheaper Silver interior. XL plus: 150cm X 150cm X 200cm(h) XL plus-HL: 150cm X 150cm X 220cm(h) These tents are suitable for up to 1000W HID lights or the equivalent LED lighting, people do sometimes push the limits and put 2 X 600W lights in the XL plus-HL but this makes managing the environment a bit more challenging. If you are going above 1000W in this tent we recommend: if using HID lights go big on extraction (low powered 200mm fan as an absolute minimum). ensuring you have some control over air-intake temperature (ideally an active air-intake). plenty of air circulation within the tent. We recommend 6-9 medium/large plants in the 150 X 150cm tents though obviously this is only a guide; it really depends on plant type and personal preference. The Budbox Pro XL plus and XL plus-HLgrow tents have the following features: 2 X 275mm ventilation ports. 2 X 100mm cable ports. 2 X 225mm air-cooled lighting vents 2 X passive vents with Velcro covers. up-lift bar to allow for incoming irrigation lines. Strong, black, powder-coated 25mm steel frame. Quick-lock, push & click pole assembly. Green viewing window. Very high-quality zips. ‚The Budbox brand has been at the very top of the grow-tent market since the beginning, we sold them for a decade before moving more exclusively towards the Secret Jardin range around 5 years ago. We recently took another look and the guys at Budbox certainly have not stood still! They have refined the product and expanded the range resulting in a truly comprehensive range of grow tents that are rivalled but not beaten on quality or price.
