How many watts do I need for my small tent?
noobiiistarted grow question 3 years ago
I am using a full spectrum LED that draws only 30W from the wall but it might be too weak since my plant is getting lanky. I have moved it closer to the plant but now I am afraid of over-heating. How many watts LED would be sufficient for my 40cmX40cmx120cm tent?

Meter that light if you can...that's really the only way to really know what it's delivering at any given height, though 30w seems scant at best. You might want to look into running your light 20/4 or even 24h to make up for lack of firepower with extra exposure time...you'll probably have a better chance of success. Before I went and bought a higher powered light I was sitting with ~100w or so and an experienced professional grower suggested I go 20/4 or 24h to make up for lack of delivered PPFD.

You wanna have 30-40 real watts per square foot. By real watts I mean what the light fixture pulls from the wall- not the watt rating the manufacturer has on that specific model.
I’m currently running enfun lights. They are called EF2000- but actually pull 240 real what’s from the wall. 🌱

Should the first tiny node be removed?Hi guys! So this is a fb auto day 22. I was not planning to stress train her in any way. Could you please advise is this first node should be removed or kept? It looks unusually small to me and I wanted to remove it but I've never removed anything so early. Thank you, growmies!

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.

Will this tape repair a broken stem?Should I re-wrap this broken stem? Bent with too much pressure and there was a snap, though not completely severed. I applied two or three layers of duct tape, not sure if the constant pull of ties will allow it to heal and repair. When should I take the tape off?

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 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?

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

The pictured one did, but ver strangely: Thin, weak, extremely long branches carrying a multitude of popcorn buds. Grower is experienced. Any ideas about the cause?
