HPS lamps are known to concentrate most of their output in the red areas of the spectrum, which is great for fruiting and flowering, boosting the weight of the harvest while increasing essential oil production for better flavours and aromas. With dual-spectrum technology, you're also getting a decent level of blues thrown into the mix. \u003c\/p\u003e\n\u003cp\u003eThis helps to keep internodal lengths down, concentrating growth into smaller areas. It will make better use of the space in your grow tent, keeping the height down and creating an even canopy. The extra blue also means that you can use these lamps in the vegetative growth stages, though there are better alternatives available if you want to really fine-tune things.\u003c\/p\u003e","brand":"HORTIKING","offers":[{"title":"Default Title","offer_id":44056841945303,"sku":"9180","price":20.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0561\/9092\/7032\/files\/grow-lamp-hortiking-600w-hps-dual-spectrum-lamp-39478582935767.jpg?v=1693265524"},{"product_id":"philips-master-greenpower-son-t-pia-600w-230v-lamp","title":"Philips MASTER Greenpower SON-T PIA 600W 230V Lamp","description":"\u003cp\u003ePhilips Master Greenpower 600W \/ 230 Volt SON-T HPS Lamp is suitable for 230v\/240v  -\u003cstrong\u003e must only be used with 230v\/240v ballasts.
