Burn or ?leafs feel rough , little tiny greens dots with texture on leaf.
I found out after bumping the light up 40% Plants did not like.
Looked up manufactures suggested hanging / power. Seems I am over powered. The light is more 4x4 or 3x3 then 2x2

Wich of those cheap lights would be advised under 200€ and that would fit both final vegging state and flowering?
The grow space is 80cmx80cmx160cm and keeping in mind that the weather along with the lack of ventilation budget limits my options to colder leds.
Thanks in advanceWeek 1

Lamp for houseplants?My neighbours fiancé yesterday evening dropped by and gave me the lamp on the photograph, I have no users manual, but I understood it is for houseplants. I wonder if it is of any use and how I can use it. Whenever the sun shines I will put the plant in the sun of course

Did I start LST too early?At day 22, did I start LST too early? I feel that I may have stunted the growth a little from overheating, but didn't want to wait too long to start training. Also, would a higher-powered light cause less distance between the nodes, and therefore make LST harder/less effective?

Ventilación y Luz en plantulasI was inspired by McGyver and set up an improvised cabinet... How important is ventilation at this seedling stage?🌬️ (I left the door slightly open just in case)🤔
I also added another auxiliary light... will it make a difference in growth or is it a waste of light?🔌🔋

PAR/PPFD and light heightPAR/PPFD: does light height matter if your PPFD is in the right range? Another way to ask: is 300 PPFD @ 2 feet the same as 300 PPFD @ 20 feet, or are there other factors involved? (assuming heat, C02, all other non light inputs equal)Setup. Lighting
