Interesting Cannacribs podcast.

I'm considering getting into some automation. For some reason, I see possible issues between say a heater and an inline ventilation fan. Can the settings cause one or both from operating properly? If so, could somebody explain to me how this is prevented? I'm probably just over thinking this as...

I'm asking for any opinions please on what strength to use for autos in RDWC. After having just converted from DWC to RDWC, with good results so far, I'm feeling adventurous and want to try changing the nutes too. I'm using the Botanicare line in my current grow. These plants are doing well...

With ppfd being equal, is there any disadvantage to having led lights farther from the canopy?

I'm planning on possibly upgrading my DWC system to recirculating when my current grow is finished and have a few questions. I'd like to reuse anything I have now if possible. I have a cooler I want to use as the reservoir. Are there any pros or cons to having an insulated reservoir? I'll be...

I just got a complete and identical Apera pH/EC meter to have for a back up. I replaced the probe on my original as it was close to 2 years old 3 months ago. After cleaning and calibrating them both I decided to compare their readings. The temp, EC, and ppm are very close between them. But there...

How does everyone resist the urge to constantly meddle with their grow or is it just me? I'm thinking I got too much free time being single and retired. At least I get some exercise going up and the stairs several dozen times a day. Pretty sure I saw my dog rolling her eyes a couple times just...

After growing in soil for three years I decided to take the plunge into DWC late last year. I went with DWC instead of RDWC because of limited space and uncertainty of success. After much research I realized that keeping my nute temps low was my biggest concern. I’d like to share the details on...

Anyone have any opinions on what would be acceptable nutrient temperature swings in a RDWC systems? For instance, how much would a gradual 3 degree swing in a 8 hour period stress plants assuming temps remain somewhere between say 67 to 73 degrees?

I'm using a simple thermostat connected to the vent duct fan to control high temps in a 2x4x6 tent. Upside it works well with a less than 2 degree swing. Downside there is no ventilation during the 6 hours that lights are off. Is there anyway to automatically override the thermostat when lights...

If using a meter everyday to check nutrient solution how often is calibration of pH and EC necessary?
