Above this range would require moving the grow light further away from the plants. To read more about PPFD and light intensity levels required to grow cannabis, read my full article on the topic here.

Next, you need to convert your Lux reading to micromoles. Luckily, Apogee Instruments, the manufacturer of the light intensity meter created a conversion table for converting Lux to micromoles. At 50, lux, a double ended HPS grow light emits uMols of light per second and about 28 Moles of light during a 12 hour flowering light cycle, or 42 moles of light during an 18 hour vegetative phase light cycle.

But there are two more questions to answer to determine what height to hang your grow light. Again, the most critical aspect of this whole process is having a Lux meter handy so you can measure, convert and compare the light intensity levels to the actual light intensity levels your plants need to grow.

If your grow light is dimmable, you can usually adjust the light intensity via a screw or knob on the ballasts. Good Luck! Want to learn more home growing tips?

A low power grow light needs to be closer to plants than a high power light. Generally speaking LED grow lights can hang between 16 and 24 inches.

HPS lights need to hang at 36 or even 48 inches depending on the power output. Yes, as the plant gets closer to the light it receives more intense light and you risk burning the plant unless you adjust your grow light height.

Grow environment: Your grow environment is your grow room so a lot of that depends on how high you can place your lights. The shorter the ceiling the shorter the plants. Source: Urdedpal at Magazine.

I have heard you can start to flower at like 9 inches, I have never seen it done besides lowryder which is short anyway.

In which you could do SoG but they would be like 1 alright sized bud maybe more anyone know about this even if they are not lowryder? GreenThumbsUp New Member. The indica is a 2x, so I grow her to 1. The sativa is like 4. The mix is about 3x on the money so I usually do her at 8"".

Urded is right on the money, it all depends on your grow environment. You'll get the hang of it after you've done the same plants or clones thereof a time or two. I don't know where along the road I missed this concept of flowering based on a veg cycle height, but I did Did I wait too long to flower?

Should I have a higher yield as a reward for my patience? Or are there any negative effects of having it get this big before flowering? Thanks for the input. You'll see a couple of pictures of my girl below I have recently taken care of the yellowing around the bottom leaves Snoogenfro New Member. To answer your Q on a one on one, yes but the plant has to reach maturity. It would be best to use a clone since it is already mature or set up a screen to do a scrog. You can also tie it down and keep retieing it to keep that height.
