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

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?

Help with issues IDI have a photoperiod in a 5 gal using BAS light. It is currently day 3 of week 4 , and I'm getting some damage on the tops. Would this be light stress or another issue? The tips are starting to go light green. Using the 200 watt light for the 2x4x8 ac infinity tent.

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

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?

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!

Blüte einleitenWie soll ich den Lichtzyklus ändern von 16/8 auf 12/12, einfach direkt in einem Tag 4 Stunden Licht wegnehmen oder step by step pro Tag 30 min weniger Licht geben, bin mir unsicher ob ein direkter wechsel zu Zwittern führen kann, wie macht ihr es?Setup. Lighting

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.

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!

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?

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 :)
