Which led? leds are not even close to the same. 200 watts can be dramatically different from one light to the next.

anywhere from 12" in flower (depending on your diodes) to 24" in flower... (depending on the diodes).. A safe veg height could be anywhere from 20"-36" .. Need to know the brand and model name of the led if you want advice about it.

Ist mehr Licht besser!!!!
Hi liebe Grower Kann mir jemand sagen, ob das stimmt wenn man mehr Licht bzw Watt hat, das die Damen schneller wachsen und eher fertig sind bei Auto Samen. Überlege nämlich ob ich mir eine 2 Lampe zulege soll. Danke im voraus 😉

Autoflower kabinde Photoperiod yetiştirebilir miyim?
Can I grow photoperiod plants in the tent where I'm growing autos (3X)? The light cycle is currently 20-4. Will this keep the photoperiod plant in the veg stage until I harvest the autos? So, can I apply a 20-4 light period for my photoperiod plant instead of 18-6 during the veg phase?

Hi all, Are the leaves point upwards a good sign of a happy plant or a sign of too much light? This is my first grow and i am trying a variety of setups and just trying to be cautious as what I have read in the forums is either one way or the other. Thanks!

Temperature VS More Light which is better for buds size and potency
Should I continue to use two LEDS if temps are reaching 87f during flower (day 1) or just move plants more towards center of tent and use one LED for better temperatures (75f) (only growing two plants). lights are 1000w bestiva and are in a tent that is 24"x48"60".

Supplemental light for flowering?
I have a 300w quantum board LED. Its a Mars Hydro TSW 2000. Should I add more light of a different type for flowering or should I just run the LED alone? I've heard people mention the UV-B lights.

Autoflower 24hrs of light?
AUTOFLOWER - I checked on my seedlings this morning, and the temp in the tent dropped to 9 degrees celsius during the night. My light puts off a bit of heat. Am I better to run the light 24hrs and maintain a warmer temp, or give them a few hrs of darkness and risk dropping temp?
