I have noticed in 2017 - 2018 that many of the hydroponic shops are advertising illegally when it come to many Items like extraction (Ruck) now known as Can-fans. Here is a few examples and links to the 2 shops I found adverting on the online shop or Amazon. Somerset hydroponics on Amazon claim to be selling (at extremely high prices) The first one I found was for: CAN-FAN (RUCK) RKW 100L Temperature Controlled Grow Room Fan https://www.amazon.co.uk/CAN-FAN-RU...1&keywords=can-fan+temperature+controlled+fan And the 2nd was for a: CAN-FAN (RUCK) RKW 200L Temperature Controlled Grow Room Fan https://www.amazon.co.uk/CAN-FAN-RU...2&keywords=can-fan+temperature+controlled+fan They clearly tell you it's Dispatched from and sold by Esoteric. Now I know for a fact because I already had been in contact with Esoteric also known as w w w.1-hydroponics.co.uk who I nearly placed an order with, When I double checked with them to see if I would be getting the correct fan I was about to order. (see link below) They told me - NO - They had phoned around and these fans are NO LONGER available and would be more than happy to dispatch me a replacement Prima Klima Thermostat Controlled Fan. http://www.1-hydroponics.co.uk/fans...fans/can-rkw-temperature-controlled-fans.html Who? What? Hang on a minute !! You was advertising the CAN RKW150 Fan 6" 150mm - 460m³/h (£173.00) CAN RKW150L Fan 6" 150mm - 700m³/h (£196.00) etc etc Nearly 3 weeks later and still they are advertising these RUCK/Can-Fans FOR SALE When they do not have them in stock and can not get hold of them. Hear is what was said: They said: We do not have them in stock, We phoned around & We can not order or get hold of one for you. I said: But you was willing to take my money and are advertising them on your on-line shop (web-site) They replied: We would of sent you a replacement fan Hang on a minute, Let me see if I have this right, I want to buy a Rolls Royce (fan) and you have not said OUT OF STOCK and was going to send me a MINI in place of a Rolls Royce for the same price Why don't these hydroponic shops REMOVE the ad's or at least state: OUT OF STOCK or NO LONGER AVAILABLE Don't believe me, contact both hydroponic shops and ask them yourself by phone or email. Let me know what replies you get.
