It's the perfect light for re-vegged a clone, I have done it a few times, even in late flower, keep the t5 12" above the clones, take a few weeks, they won't all root.

Your pot size looks a little small and your plants will benefit from thinning the canopy out.

I tried flowering under MH, the crop size was lower 3000k higher output vs 4000k (umol/m2)

does it reduce crop size? thought 4000k+ was a veg light

I have cut all the buds off the stems and trayed them up, the plants weigh between 167g and 205g Still need to do a little trimming and the buds may lose 1-2% more, chopped the plants when they were dry. so I could still lose 5% of the weight, total weight is 1,104g -5% = 1049g my led was about...

That's a fair comment, so there a big difference between 3000k and 4000k? I have some 4000k bulbs I will buy a few more for my next crop.

we are talking about the OP, his flower space plants, LED, and what the yield is likely to be. Don't think anyone can pull 1g/watt with hid lights. Most growers will pull between 0.5 and 0.8g/watt with hid lights.

Vertical grows will start coming into play in a few years' time, you would be able to double your crop size. That's what I am going for next time I set my flower room up. 4ft x 4ft flower room, you could grow one massive 2.5ft x 2.5ft x 4ft covered in bud, just like the ones grown outside.

OP is flower his plants off with a electric sky led v300, 300x 1.5 = 453g/1lb 1lb is a good size crop in a 4ft x 4ft but this depends on the amount of light, 1kw de HPS might hit 1.5 lbs electric sky led v300 is designed for a 4ft x 2ft flower room, so its not ideal for a 3ft x 3ft I think a...

Sorry PJ Diaz, I wasn't trying to put words in your mouth, 800-1000umol/m2 /s to me is ideal, and with co2 may be up to 1500. I think for 99% of growers, adding co2 is a waste of time for the extra resources. Wife has been told to self-isolate again(in contact with a child with Covid at...

Are you saying 2000 par would be good for your plants with added co2? All the advice I have read says 800-1000 at the canopy level, do you know of a single grow diary on here where they tried 2000 par at the canopy level and pull a massive crop, I would like to see this.

I don't know the PPFD of full sunlight, I don't grow weed outside but i have seen my canopy get light bleached under HPS.

Should of said, could i have a rear view, is it too hot to handle when it's turned on ;)

This chart says it's possible, maybe with a few strains and a very high level of CO2 you could pull it off. If my lux goes over 70k and my humidity a little low, seems to really mess my plants up, most of the best LEDs seem to be aiming for 800-1,000 par don't see many hitting over 1,500...

I have bleached my canopy a few times, white buds, etc it's not fun, give it a go if you want too

like Godfather OG or Strawberry Banana(Indica strains also have a very high level of THC) Not always, it can be hit or miss depending on a lot of other factors, most of it comes down to the skill set of the grower to control the stretch and flower the plants off at the right time. This chart...

So adding some CO2 means I can give my plants over double the light?

yeah, that's not quite true, helps to sell LEDs, if the LEDs are too close, you will flower off white buds and light can really damage your canopy. following the advice of the video, my plants would be ok with 150,000 lux at the canopy level. :rolleyes: Give it a go see what happens, I keep mine...

Every plant from seed is different, even from a pack of seeds, how much would LEDS reduced the stretch, you will never know.
