18/6 leads to high temps in small tent; change light schedule or stick it out?
ItsGrowingOnMestarted grow question 3 years ago
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

Change your light schedule so that the lights are off during the hottest part of the day is one simple idea.
Yes, yields will be lower with less light and be higher with the more light and more heat situation.
High temps during flowering will actually increase trichome production.

I've run with my tent open and a fan blowing into tent when very hot.

If I were in your shoes I would first try re-adjusting your 18/6 schedule -- having your lights on at night when it's coolest inside your home & lights out when it's warmer during the daytime.
If you have space possibly a portable AC unit or a homemade one?

Circulate more air from outside tent in. Sounds like you do not have a flow of fresh air going In and comming out. The smart controller fans are really nice from spider farmer or Mars. Temp and humidity control. I recommend using the filter to reduce noise of fan when it runs. Do not lower light levels on autos. It will hurt your yield greatly. If anything get the exhaust fan, and run 20/4. They do need some rest though. About 82, 83 degrees is the highest I let mine get.

UV LED slowing down growth? Sorry previous question without the question!The plant has a rectangular area in the middle where it is not growing as quickly. The difference is almost 10cm. I suspect the lamp. Could it be that the centrally installed UV LEDs are causing this? They should grow more inside because of more light.

Started the plants off with 60 watts. Increased to 100 watts today with a 20/5 schedule. Could I increase to the full 150 watts already or should I give them a few days with 100? Thanks in advance for any advice. It’s my first indoor grow with this setup and I’m still learning :)

Hight ProblemsI’ve got 3 plants in my tent, but they’re all different heights. To compensate, I’ve hung my light at an angle, so one end is closer to the smaller plants.
My question is: Does this help, or am I better off keeping the light level? Any tips for dealing with uneven plant heights?

Stretchy seedlings...worried!Hi, I have 5 seedlings on day 7. 2 of them are going fine but the three from ditch passion were very stretchy though. Likely due to having the light to far away. Take a look, any advise would be great. Cheers all!

Wrong power cable in my LED light: still light when switched down off.Have you ever made this mistake? My second harvest was someway worst then my first. Sure I did some watering mistakes but during my chores in the room and in the tent, I found out. I used a random power cable on my PAR LED lamp so when It turned off still had some light on. Bang!

Will increasing light intensity restart stalled seedlingsSeeking advice from Mars Hydro TS1000 growers. When do you increase light intensity during seedling stage? I've had the light 30cm above the plant at 25% power since germination. The plants stalled 2 weeks ago. Can I get them going again by raising intensity or will I fry them?

Do you lower light intensity and temps towards the end of flower?So I’m in mid flower, start of week 7 to be exact. I’m curious on when you guys start pulling back light intensity and going with a little cooler temps. I’m running a 240W S33 from AC infinity in a 3x3.
Should I be going strictly off of PAR or VPD at this point.Setup. Lighting

How to manage a tall plant with a thick stem in week 1 of flowering?One plant I ordered online was pre-grown. Now, it’s about 20 cm taller than my other plants. At the top, the taller plant gets more than 1000 PPFD, while the lower canopy gets about 500 PPFD. It’s currently week 1 of flowering. The stem is too thick to bend down.What would youdo?

How many plants in a 70x70x160cm tent with 100W?Hello, I have a grow tent kit 2x2 with a 100W 301H EVO Spider Farmer light. I have put there three 11L pots. But now I realize the size/light of my tent might not be enough. Could I manage by adding an additional 60W lamp you reckon or is it best to discard at least 1 plant? Thx
