New update got my new grow light dialed in.. And the nutes helped a lot seen more growth in one day than I had in the last 23 days! I am worried that if I place the light at the recommended height (6”) that would be too much so I’m running the lights at 50% power and at 12” away

Danke für die Antworten. Ich werde sie aus Zeitgründen in ihrem Zuhause belassen... aber gut für den nächsten grow... Wenn ich auf 12/12 umstelle soll ich dann auch gleich die Lampe wechseln?🤔

How many watts do I need for my small tent?
I am using a full spectrum LED that draws only 30W from the wall but it might be too weak since my plant is getting lanky. I have moved it closer to the plant but now I am afraid of over-heating. How many watts LED would be sufficient for my 40cmX40cmx120cm tent?

Low Humidity and high temp or high humidity and low temp?
Do you think it’s better lower temp and higher humidity (like 27 degrees c and 80 % humidity) or higher temp and lower humidity (like 29 degrees c and 60 % humidity)? I’m just waiting for the humidifier but in the meanwhile I have to fix somehow. Thanks!

Is it worth adding a LED 18w 2700k strip light for last few weeks of flower?
Should I add this light for the last few weeks of flower? I have a Streetlight 18w LED strip see pics. I was thinking that if I added this strip designed for flower to my tent like a side light it may help my Viparspectra V300 in fattening those buds a little. Thoughts?
