If your grow room gets hot, or the air is stagnant, or your concerned about lack of CO2, then air exchange can resolve the above. By simply extraction you not only keep to the temperatures that the plants love to thrive in but you achieve better air circulation of stale air exhausted of usable CO2. Depending on grow rooms some people extract hot stale air out as well as expelling fresh air in, for complete air exchange, however a sealed grow room using a single extractor can cause a positive pressure, pulling air in from an available inlet. It really is a case of suck it and see. We do offer a complete upgrade service, if you find you bought a fan from us that is to small for your needs, we will part exchange at full price against the price of a bigger one, this applies for all of our equipment. The filters we offer cleans the exhausted air of any unwanted odours that your plants might be producing, they also act as great silencers.
Carbon dioxide (CO2) is essential for plant growth. In an enclosed growing area, as plants use up available CO2, their growth will slow down and may eventually stop. Replenishing CO2 will not only maintain growth but dramatically increase it. The average level of CO2 in the atmosphere is about 350PPM [Parts Per Million]. Through years of agreed upon practice, the agreed upon optimum level is in the 1000-1500PPM range. At these levels it is not uncommon to realise 25-40% increase in yield. In the absence of CO2 enrichment equipment, the common way of replenishing the CO2 content in an enclosed growing area is by an extractor fan. This draws in fresh air and with it ambient levels of CO2.
This really is the easy and effective way to use CO2 injection. The advantage of this kit is that it comes with it's own built in special CO2 timer so that all you need do is tell it the size of your room and it does the rest for you. Designed for small to medium growrooms; use in multiple for large growrooms. Complete with informative instructions and five metres of CO2 dispersion tubing. Requires bottled CO2 (not supplied).
See Environmental Controls for combined CO2 and fan controllers.
The Evolution Co2 Controller comes in two parts:
Evolution Digital Carbon Dioxide Controller
This Controller is the most advanced of it's kind and has more features and functionality than any other product on the market. It can be used either with or with ought the Evolution Carbon Dioxide Sensor and can be interfaced to an external thermo / hygro stat providing a cheap entry level system with an easy & affordable upgrade path in the future.
The Evolution NDIR CO2 Sensor
The Evolution CO2 Sensor utilizes non dispersive Infra-Red sensing technology for fast accurate CO2 monitoring. Combined with exquisite design and ground breaking low price the sensor is highly accurate and less than half the price of similar products on the market and making available the ultimate control system to the average grower.
A simple to use, innovative CO² sensor and controller, the Harvest Master CO² Easi Controller monitors the growing environment of your grow room – vital for healthy plant growth!
The operation of CO2 EASi.
CO2 EASi is intelligent control of CO2 and at the same time, an Intelligent Temperature controller when the COOL KIT is attached.
In Light ON periods (Day):
The controller will try to maintain Max co2 high PPM for the longest duration. It aggressively maintains the CO2 at and just above your target ppm value.
It will use COOL output to try to keep temp within 2’C/F of the Target Temperature (say 25’C/75’F).
If the temp rises too high (or there is no COOL unit), the FANS are activated at Max Temp, say 32’C/90’F.
In Lights OFF (night) periods:
The controller does not need to maintain CO2 levels.
For temperature control, automatically uses FANS as the cooling control, but will use COOL output if the temp stays/gets too high (as when the outside air being drawn in is from very hot outside)
Efficiency Monitoring.
On the display, you will see the “Efficiency % monitor”.
This unique Harvest Master feature is calculating how efficiently your room is operating!
• If FANS are activated, this is “wasted CO2 ”, reducing the efficiency.
• If COOL is activated, 99% efficiency is possible.
If you have been achieving high efficiency, but suddenly see a low efficiency rating, are;
• Door seals ok?
• CO2 device operating properly?
• Cooling unit operating OK?
What is wrong, that you may not have noticed otherwise!
Usage monitoring.
CO2 EASi has a “CO2 bottle life” timer.
Another unique Harvest Master feature!
• When emptied, select “New Tank” to reset the timer.
• Shows “% of Last tank used”, so you know to get a new tank organized.
Instead of using bottled CO2, which sometimes can be difficult to obtain. This system burns propane gas (available nearly everywhere) to create atmospheric CO2. Like the Unis CO2 Controller, the Growth Gas Generator is supplied with a timer for really easy and effective injection. Requires bottled propane; not supplied. There is an extensive GrowthTech DataSheet for this product.
