Advice for

I would go hlg , or budgetledgrowlights if you wanna go cheap alibaba has good cheap led also does maxisun on amazon the maxisun in my opinion is better than sf and cheaper

I'll elaborate... The SF-4000 is like 900 cad.. You can get a great COB light with the same warranty and/or better for half the cost... You can use supplemental lighting to cover the corners the higher intensity cobs don't get and boom bobs your uncle.. Quantum boards are only made by one Company in the world. There is a serious Advantage to getting cobs.. Here is two equal coverage lights.. One is twice the costs one uses 150ws more but has a higher intensity. If you have the Vertical Height get a COB if you are height limited get a quantum board. They both have Value. You be the judge. Canada links and prices... But you get the idea.. https://www.amazon.ca/Spider-Farmer-Grow-Light-Commercial/dp/B07TXNBTL4/ref=sr_1_1_sspa?keywords=spider+farmer+sf4000&qid=1586190541&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyUDlLSFNGUTRXNk8wJmVuY3J5cHRlZElkPUEwMDQyNzE2Mk1YSkxXVkpIQUhRViZlbmNyeXB0ZWRBZElkPUEwODEwMDAxM1VIT1UzV1JaOUsyWSZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= http://www.cobledcanada.com/product/2800w/

Before you run out and buy a spider farmer. Please read this, it's long but it explains a lot... https://www.canadagrowsindoors.ca/best-cob-led-grow-lights/

Hey there, I'm in a 4x4 tent and loving the SpiderFarmer 4000. Amazon buy. Grow in Missouri and no heater is needed, no ac needed

I'd check out the Spider Farmer, Mars Hydro and HLG quantum board lighting series. Each are quality and well priced w/ higher efficiencies and output without larger draws to power. Not too mention pure white light is a nice deal 👍 There is no "Best". That's up to you. Check specs of any light you're looking at, side by side, and you'll know what you're looking for. Good luck and happy trails. Welcome to the obsession 😀

Hi mate.the best leds at a good acceptable price that are on the market are the bestva elite and hydro mars SP series. search on aliexpress, there both sell at better prices than on ebay or amazon. Good luck mate

I really love the Mars Hydro Quantum boards, TS series. the light is a good spectrum, white 3500K IIRC, and price WAS great, gone up a bit of late but still good price for a good light.
