I have a 100w light in a tiny tent with no dimmer. My canopy wound up like a bowl shape on this run because the plant wouldn't cooperate height wise. I've got some leaves taking a beating for sure but the buds are basically perfect and most are getting 1000 umols or more.

If the cabinet you're growing in is in your bedroom, run the lights at night while you're sleeping. It's free, abundant CO2 and you'd be surprised how high you can get it. This plant is getting 800-1000 ppm just from being in the same room as my wife and I and it just shrugs off the light and heat like no big deal.

The power and duration of your light (DLI) is the engine that drives your entire grow. Trying to maximize that should be a top priority, so it's better to find that upper limit and back off than never reach full potential.

If you want to make an omelette, you've got to break some eggs!

Here is a couple of photos of the tops of the plants. The plant in the first photo is quite light in colour compared to the other two plants but to be honest that plant is probably less centered under the light. Doesn't show very well in the photos. I did this morning lower the light by a few Centimeters and bumped the light from 90% to 100%.
Like mentioned the plants are quite leggy so its hard to believe its light stress. Would you say they look generally healthy?

Yes. When they sell LEDs they try to sell the best they can.
I can be a bit confusing when they show a picture showing 45 cm and a good looking plant.
But that is a bit misleading. It makes one think it's 45 cm in flower.
I think what those two pictures together is telling = 45 cm for veg and 30 cm for flower. At 100%. Seedlings don't need much.

And your plants looks really good if you ask me

Ok well i installed the CLOUDLINE PRO S4 and added a second isolating fan (Vivosun E6) and i still can not get my humidity below 60%.

If i run the CLOUDLINE PRO S4 between speeds 1-2 i can maintain a slightly higher temp as the air isn't sucked out as fast but that also means the humidity goes even higher. Its currently on speed 4.

For a basic easy test i will replace the pre filter sock thing over the carbon filter

Any further suggestions?

Help! Im coming into week 4 of flowering and im really concerned about mold/rot and this all being a waste of time and money.

Have you tried using the auto mode? Set high temp trigger to 80° and high rh trigger to 60%. Make sure the "low" triggers are set to "off".

Before you do that, set the power to 7 or 8 in "on" mode. The fan will cycle itself and only use the higher speeds if it has to.

I have the same fan and this works great for me. As flower progresses I lower them to 78°/55% then 76°/50%

Hi,

Thanks for the suggestion. That would require the smart controller? I don't think the fan itself has this. Only a 10 speed manual mode.
