Hello everyone. This if my second dydro grow. The strain is Nirvana's Snow White. Today is the end of week 8 of flowering. Tomorrow begins week 9. I've read some conflicting accounts of what color trich's should be at harvest. Hoping for some input from some growers with seniority. Thanks for...

The plc controls all timers. Its also tied to a temp/humidity controller and then runs the exhaust/intake along with dehumidifier accordingly. There is also a float sensor in the reservoir which prevents the pump from running if water falls below a safe pumping level.

Just wanted to share with all of you my venture in growing. I'm utilizing two bedroom closets. One closet contains the mother, and clones, and the second closet is the flower "room". Both closets are lined with mylar. The flower room is controlled via a Programmable logic controller. All air is...

Thanks for the reply, anyone else had a chance to grow this strain, and recalls how tall their plant was before they switched it over to flowering, and then how tall it was at harvest?

Just curious how tall this plant will typically get if vegged to only 12 inches before inducing flowing... Thanks for any help!

I have browsed through several online "troubleshooting" guides, and I haven't been able to come to a confident conclusion. Thank you for the suggestion though. Just hoping perhaps someone has seen and then alleviated a similar problem.

TDS is at 700 ppm

Hello everyone, this is my first grow. This sample was taken from the upper part of the plant. The leaves are beginning to turn much like this leaf from the top down. Everything on the lower part of the plant looks fine still. buds on the lower branches are almost fully mature, but the main...

It is going to be very close, one thing you could do is check to see the gauge of wire used for those circuits. If its 12 gauge wire you could purchase a 20 amp breaker to run the circuit.

Hello, im pretty new here. Also an electrician. I typically deal less with wiring installation and more with automation, specifically programmable logic controllers in an assembly type environment. I'd also be willing to help answer questions related to wiring, sizing, controllers etc. It might...

Thanks for the input so far, anyone else seen similar curling on the buds only?

It is aero PH is at 5.8, I'm running the nutes at 70% listed strength. 1 minute on, 5 minutes off nutrient cycle a constant 70 degrees and 30 percent relative humidity.

This plant is not yet in full flower. New bud leaves come in fine, and then curl down as new growth begins above it. Yet the auxiliary leaves remain to look great. What could be going wrong? See pictures attached. And thank you for any input you may be able to offer.

Trying to stay on topic... how man of you are using TOR? The Onion Router. Fantastic Anonymity.

The only SSR's I've used have controlled either purely resistive heating circuits, and transformer vibrators. Their leakage current creates a dilema for alot of scenerios.

Hello Everyone. I want to try the advanced nutrients 2 part sensi grow, and sensi bloom for my next grow in a hydro setup... However the advanced nutrients calculator assumes you want to purchase their other 10 million additives. For those of you using advanced nutrients could you please...

Hello everyone, I was hoping someone could answer a quick question I have about advanced nutrients' calculator. I'm at their website, I have the nutrient base set at "grow micro bloom" but im confused about setting the correct "formula" selection. They have "Plus program bloom" in various...

If you look above I have examples of Ladder Logic... if your talking about schematics for designing an automated system around a controller there is no "exact" schematic, every system is 100% customizable, starting with your controller and then deciding how complex you want to go.

Yes... except a little more complicated hahaha. Your res would have a water level sensor..., the plc would know whether or not the lights are on... (its controlling the output for the lights)... the water reading could be an analog input from a probe sensor... the analog signal is scaled to a...

HAHAH! Someone i can talk automation with. My larger controller is an allen bradley SLC 5/04... I have a 10 slot rack with a backup 24 volt power supply for suplimental needs. I have 3 24 volt sinking inputs modules, 2 24v sourcing outputs, 1 8 relay output module 1 8 point Analog input module...
