The light is to far away. You have a dimmer so you can put the light closer and run it with less power.

LED glass/plastic cover.
Glass/plastic cover on cheap led lights.. do you remove them or not? From keeping reptiles I know that any glass/plastic will reduce UV. Just wondering if anybody's noticed any difference after removing the glass.

Switching light schedule for an auto and Phototype!
I'am growing together an auto and a phototype with 20/4 light circle. For my phototype is about time to change light schedule for flowering, will my auto be badly impacted by switching to a 12/12 light? Or should I move every day (same place but no light) the photo for the night?

Bloom light on heat goes too high?
When turning on the bloom setting the temps seem to be getting up to 84 on the very top of my tent and around 80-82 by the bud sites. Is this too high? Is there any problem turning the bloom high power switch off to let it cool down for a half hour once or 2 a day if too hot?

Would this be an upgrade or downgrade?
Currently using a 400w HPS on a 18/6 schedule for my autoflower. I've just seen this being sold on FB and wondered whether this might be as efficient/better/worse than what I already have Appreciate that it's a 'budget' light, but still looks pretty good š¤·āāļøš¼

1 light or 2
I have recently purchased a Mars hydro SP 3000. Great light.. It replaces my Blurple Mars hydro exo 120. I wanted to ask what peoples opinions are about me using both lights for veging. My grow space is not that big. 1.8m x 0.8m and 2.35m high. Will it be too much light and heat?

Light strips
Opinions on led strips down the poles of my tent for extra light or saving up for an upgrade.... I've been talking to a fellow grower and I know I need more light in order to have a better yield. I thought 4 light strips would give light from each side plus on top. Whatcha think?

Sorry hat the question earlier before but I'm new here so I dont know how to undo the solved quesion status. The LED has about 300W and I want to dimm it. not simply turn it on/off. Preferably with some kind of integration in home automation systems like Home Assistant. Thanks :)
