Grams per watt
OutForRealanswered grow question 5y ago
You could be surprised by the final yield even if it could be less than what you are expecting.
I also feel like gpw is not referring to gram per watts per plants , it is a calculation for your grow area depending on the light power but your space could have been used by 2 plants that could perform a twice higher Gram per watts

have a look through the diaries there are not many that achieve 1gpw
Aim for 1 gram per watt for sure whether you get there or not
Good luck

Hey growmies✌️💚, so I finally have a PAR meter. With all my 3 LEDs on at the lowest setting I reach like 77 umol max. What would you recommend for seedlings that small like in the picture? I saw seedling/clone 100 - 300. So just wondering how much for my little flowers? 😁✌️

Irregular light schedule.I am thinking about giving her 24h lights a few days a week and then go back to 18h. Just to give her a boost. Will this irregular light schedule harm her?
My first thought is that it doesn’t matter much since she is an auto, however I know that plants love balanced environments.Week 3

Is my LED too close or too far from my plant?So this is my first grow and it feels like she’s growing a bit slow. Currently at day 10. Distance was 62 cm. The LED is 100W. Now the distance is 57 cm. I’m wondering if I’m just impatient. Is this distance appropriate? How is the growth looking?

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

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
