Lamp distance from seedlings? PPFD uploaded in this weeks photos.
How far away I should have my lamp from my week old seedlings? I think it has something to do with the PPFD for my lamp (TS600), but I have no idea what it means. The lamp is set right at the very top of my tent now and is 32 inches (81cm) away. See photos in week 1.

Is your machine helper leaking light?
Everyone has their ACs and dehumidifiers and whatnot machines in the grow space. Are you covering every little light of those machines in the flowering chamber? Many hermies will be avoided with some aluminium tape. Stay safe, cover those lights and grow ganja!

How much light does a seedling need?
Is there a limit to what it can use? Could an LED grow bulb a couple inches away provide enough light? Up to what age? Thank you so so much. My first grow and I really appreciate it! Specifically this one https://www.gelighting.com/led-bulbs/e2624/ge-grow-balanced-spectrum-br30#

18/6 leads to high temps in small tent; change light schedule or stick it out?
Girls are at 18/6 and 3-4 hours before lights out the tent gets up to 90 degrees and humidity can’t compete. Should I wait it out or try 16/8 moving towards 12/12 close to flowering (autoflower). Will lowering light exposure affect yield more than high temps would at 18/6

qu'elle est le plus important à prendre en compte le nombre de lux ou le PPFD/DLI
lux, ppfd et dli. en faisant j'ai réalisé qu'il était dur d'avoir un ppfd entre 500 et 1000 pour la phase plantule sans dépasser les fameux 7000lux on approchent plutôt les 25000lux si on veux atteindre le ppfd souhaitable pour cette phase. comment faite vous?
