Heat problems changing HPS for LED,need advice

Hi there, i personally have been using a phlizon "1000w" on my 80x80 tent and i find it to work just perfectly, im not a salesmen but i am satisfied with this one, if you get a phlizon "2000w" you will be more than fine with it, ultra cheap, dual switch, no heat at all, and i have 43° outside temps and still there is 30° in the tent, sits at 32° with both switches on. And they sell it as a full kit, p.s. you find it cheaper on ebay than anywhere else. Even contacting phlizon directl they couldnt match the ebay's price... wich is set by phlizon... go figure. Best of luck m8.

that's the ~Minimum.. not suggested.. you can go up another ~100% without co2.. and ~300% with CO2. Those would be maximums before you are in ballpark of hurting your plants.

minimum 720umol/s at the canopy, average when used on a 12-12 schedule for a photoperiod in bloom. (500 x 1.44M = 720 ). You'll likely want more than that.. 10-20%? depends on height of light and how much you lose to absorption and missing plant. Not all LED are created equal. Efficacy is key. Anything 2.7-3.0 is as high as you can get. You can use this value to understand the true cost of ownership of a light. So, make sure what you look at provides a minimum of ~800 umol/s. Comparing efficacy of 2 units can lead you to true cost of ownership. Many times the less efficient lights are more costly within 12 months when you consider electricity costs... then, they continue to cost more $$$ every year you own them, and the less efficient tend not to last as long, so you replace them more often too. cheaper to buy often is not actually cheaper to own. If you grow autoflowers... you need less umol/s. Take 2/3rds of what i said if you run 18/6 schedule (12h/18h x 800+ = ~540umol/s for 1.44m/2 minimum at the canopy, not diode!) just take the values i gave and multiple by ratio of hours 12/X - X being your # of hours run. It is proportional.

Привет, бро! 👋 Даже led 400w эффективнее чем hps 400w, так что ты только выиграешь от этой замены! 450w led будет прекрасным освещением для твоих условий! Рекомендую и поддерживаю твой выбор! 👌😇👍 Удачи, бро!

Should be more than enough and imo be better by far than the 400w hps. Happy Growing! 🤟😜

Have you tried adding in extra exhaust fans into your open vents? It would be cheaper but can't guarantee it will lower it enough. But a 30 dollar experiment might be worth the loss? With that budget both mars and spider farmer are a good choice. Just check the lights coverage area before you purchase.
