Hello everyone! I had a problem with the hps lamp,...

Switching lights won't affect your plants provided you set your light at the proper distance from your plant for LED use or HID use both charts are a little bit different . Your LED light should run much cooler then your HPS light however based on the stats Im reading your day time temp is 29c to me thats a little high and you may want to consider trying to lower the temps by a couple degree's this will help your plants to perspirate better allowing them intake CO2 better .You can try various things to help get the temps down in your grow room my first suggestion would be to get a bigger exhaust fan this will help cycle out the hot air thats being built up in your grow space , you could try plugging in an AC outside your grow area allowing your intake fan to suck in the cold air and the last thing I can recommend to have your exhaust flow directly outside your grow area and home launching all the hot air outside . Lastly I would recommend doing your foliar spraying just before the lights turn off , I say this because the beads of water on the leaves will act as little magnifying glasses and may intensify the light to the point it causes damages . I hope this information helps you on your cannabis journey ! -Happy Growing!

less light less stress, no problem my friend.

You mean downsizing the light? No it will not cause problem. If you mean if the high temperatures can cause issues, yes of course. Just be sure to adjust the light canopy distance.
