Growing in flood and drain tables in 6" rock wool cubes. I have been flooding my tables to 3" once a day in flower and have come across some posts that show flooding to as low as 1/4" and twice a day. This would have advantages as it would require smaller reservoirs and less waste and expanse...

Anybody using a Ozone generator in their Res? If so what kind and do you think it help keep the solutions cleaner? TX

ran across this article and found it interesting. Not sure if I agree 100% with the conclusions, but judge for yourself..... Green light: Is it important for plant growth? Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still...

Not quite ready yet, I think. to many clear trichomes yet...

Second grow in rockwool cubes, flood and drain. They are looking good. Thought I was having nute problems then had an epiphany. NUTE LOCK.....:wall: Flush, flush flush... should be good by the time they finish. No amber tric's yet. First pic's I've posted if they show up.

Why is it every time I try to leave for, as short a time as 8 hrs, something has to go wrong with the grow.. Tonight a stupid breaker blew, one that has never blown before, and I split the power apart and added a new circuit for the one that was blowing.. WTF It is worse than a new baby...

Thinking of adding ac and co2 to my current grow. The easiest place to put it would have the cold air blowing directly on the plant canopy. Is the cold air blowing on the canopy, buds and such a problem? For example 60 degree air blowing into and on to the canopy in a 85 degree room.

In the process of designing a new grow room for a flood and drain grow and want to know if anybody has gone up , 16 foot ceilings and two layers of plants? This would be cheaper than a larger building with twice the footprint. I think if I use heavy steel racks, like the kind at Costco, I...

First grow and everything that could, did go wrong :cry:. Ended up with 5 Hermaphrodites in 2 different species out of 13 plants. I am hopeing that it was environmental, as the power went out and the temp in the grow room droped to just above frezzing, plus it was dark for an extra 8 hours...
