New member here, but already finding the Australian-focused discussion so great amongst a sea of largely US-based websites. Next week I am beginning my first grow. I have experience growing other flowers, and I am enjoying reading and learning a lot.
My plan is to put two 600 Watt LED panels (I am confident in my choice; I understand the HPS system, but it won't work for me in terms of initial cost, upgrading is an option down the road) in a 1.5 x 1.5 x 2.0 tent. From what I can ascertain the panels will cool themselves sufficiently, especially with winter in my area. 4" exhaust fan pulling air through a carbon filter, then venting into the room, which is right next to an open window allowing fresh air, and also optional direct venting through the window if required.
I plan to use Canna soil for the grow, mixed in with about 15% perlite. I will use Canna nutrients after they have been transplanted into the grow pots from the cups, which I anticipate will take a few weeks, giving me time to get everything setup and fully understand what I am doing. PH balancing chemicals will be needed, however I am a bit confused about the role of Canna soil when it comes to PH, as I have read mixed things. Seedlings planted into seedling mix, and then raised in that with no added nutrients.
I am going to take plants from plastic cups to '5 gallon' (aka 19 litre pots) fabric pots. The 5x5 tent will comfortable fit six of these pots, and I will eventually SCROG them via a net/something similar. I am aiming to have a solid canopy that is exposed to a lot of light via the two panels. Based on some sketches I have drawn I will be able to run the plants in lines of 2, and drain them into storage tubs for water removal. SCROG screen around 25-30 cm above the flowers.
Watering plants every 2/3 days (or when the medium is dry to the first or second knuckle), nutrients every other feeding (and straight-watering between nutrients to avoid build-up of nasties). I will only use 1/2 strength nutrients at first, and see how the plant responds once it's around 20 cm tall. Managing the saturation of the medium will be important, as I am aware soil can have troubles with overwatering, but I have typically avoided this with other plants in the past.
Does anything stand out as glaringly obvious that I am missing?
Edit: Clarified some design notes.
