Deep Water Culture Tutorial for Newbies

Welcome To another Week of my DWC How to for beginners like Me This Week I will discuss the ideal Indoor environment conditions for Growing cannabis and what you can you use to manipulate the conditions if they are not at the desired levels . It is very important that your Grow room conditions are in the idal range . Key elements include relative humidity, Co2 , air circulation and temperature. ** Ideal humidity levels in your grow room is from 40-60% RH any higher ( especially poorly ventilated rooms ) and you run the risk of mold and fungus problems. ** Ideal temperature is between 66 and 76 f or 18 - 24 celcius High temperatures can cause stress and damage to plants and also raise the nutrient solution in your DWC buckets leading to root rot issues Too cold temps can do the same thing as well as stunting plant growth You can get some budget type temp and humidity meters from online shops ** Co2 additions are expensive and best left to the more experienced growers However there is no doubt to the benefits of a Co2 system for generating very fast growth ** One of the most important aspects but often overlooked is adequate air flow and air circulation Poor air movement inside your grow space can lead to bud rot which is devastaing and often leads to total crop losses You need an exhaust fan preferably with a carbon type filter to remove the odours before they can leave the tent Secondly a small intake fan that sucks fresh air into the tent at a slightly slower rate than that being sucked out by the exhaust fan. Thirdly but just as important is to have an oscillating type fan blowing directly across the plants canopy This not only helps circulate the air around the grow room but it can also help keep potential insects from landing on the leaves and establishing themselves there. ** There are a couple of other additional items that you may or may not benefit from having in your grow room firstly a small fan heater may help keep your plants warm during winter and/or when the lights are off it is important to use one with a built in thermostat so it shuts off when it reaches the desired temperature. An alternative is to use a temperature controller as pictured above in this weeks images . #Second item is a portable air conditioner , often in summer your grow room can potentially reach catastrophic temps that can harm or even kill your plants . The only resort is to rapidly cool the grow area . This is where a portable air con comes in . You can get ones with built in thermostats or otherwise use a temperature controller so that you are not running it when it's not needed. A quick note some of these portable air conditioners generate heat to cool the air down It is imperative that you also exhaust the extra heat otherwise your aircon will be struggling to work efficently. #Next item is a water chiller , fairly expensive units they basically pump your nutrients thru the chiller which cools it a cpl of degrees and pumps it back in a recirculating manner. As I said fairly expensive and for smaller grows a frozen bottle of water popped into each bucket will suffice. # Next up Humidifiers and Dehumidifiers Both are handy things to have in your grow room and there use is self explanatory. I also recommend the use of a specialised controller for both humidifiers and Dehumidifiers If you take a look at the images above there are many models and sizes to suit grows of all sizes I personally own the inkbird controller in the pic and one of the small dehumidifiers both work fine for my little grow tent and i have the controller hung up in a very visible space outside the grow tent so I can monitor the RH at a glance . A Quick note on the plants feeding this week Cyco silica @ 2mls litre (Used the last of it) Professors nutrients A+B @ 3mls / litre Seasol @ 0.5mls /litre Ozi Magic Ozi Tonic @ 5mls / litre She seems to have recovered from the rust fungus attack and a slight potassium deficiency and she has now transitioned into flowering so I will need to keep on top of her needs and provide exactly what she wants from now on 4th August Update I changed her nutes today GT Silica @ 5mls per litre Professors nutrients A+B @ 2.5 mls each per litre Ozi magic Bud swell @ 5 mls per litre PPM 1400 Ph 5.8 Thanks Once again for taking the time to look at my Diary and to the newbies reading I sincerely hope you are learning something from this grow and tutorial. See you all next week for pests and diseases 👊
