On /r/budscience I posed a link to a master thesis by one of Bruce Bugbee's students on growing cannabis at a PPFD of above 2000 uMol/m2/sec (above full sunlight intensity). I give some tips and theory as well.

If you want to play with ultrahigh PPFD levels the dual PAR build is the cheapest way to go:

How do you water your plant when it gets to a size where you can’t access the soil without removing the plant from the space bucket? Thinking about running a bit of flexible piping and drilling a few holes in it to water it evenly? Advice is appreciated thank you

First time grower here and looking for recommendations on what led lights to use in my space bucket. I bought a cheap light from eBay before I started my research but now I understand that most lights aren’t the wattage they say they are? Thanks

Hi all,

I am starting my second grow and this time i would like to add some LED strips for the lower part of the plant that didn't really get light last time. I am using a 150W ufo light. The space i am growing in is 50x50x50x50 wide and I can regulate the height up to 1,5m. Last plant i had was about 60cm tall, excluding the pot. What is the ideal amount of meters of LED strips for a similar sized plant? I was considering buying 5m 5630smd 6000-6500k for vegetation stage, and 5m 5630smd 3000k-3500k for flowering stage. Is this enough or would it be better to double up, and use 10m?

I wanted to pass this study along because in space buckets many people are letting their temps get a bit high. That's fine for photosynthesis and general plant health, but a very new study has come out showing how you are power fucking your THC levels with higher temperatures.

I've said on this sub multiple times that you're fine with your plant in the 80's F and my chlorophyll fluorescence measurements back that. But, now I'll put out a strong disclaimer that you are most likely reducing your THC levels by not keeping the plant in the 70s F.

Tl;DR- push more air

edit- fixed typo

Im a 1st Time grower and i Have a Space bucket with 30cm/1ft diameter and 60cm/2ft growheight from Soil to The top of The bucket i Have a autoflower seedling in a pre veg state and im wonderin ive heard about LST but is it recomended as The size allowed outwards is so small

Using the Photone app, I get a reading of about 390 without the lid. When I put the lid back on, it shoots up to over 800. Given the small size would it be too much?

Hey, I'm looking for light setup. I have two variants: 45 watt board (60cm thin board) using and 150 watt lamp on two thin Samsung boards (whole construction is 60x19 cm). Ofc the second one is better, but do I need that much? LEDs are +-equaly good, Samsung. I also already have 25 watt lm281b thin board, but I think that's not enough.
