I set up my flood and drain finally today also. I'll let the pics do the talking.
11 day old cuttings
24 pot iws flood and drain system
The room still needs cleaned up. Needs extraction fitted, be using airforce2 12" fan (not sure of cfm), 12" duct and large 12" rhino carbon filter. The mould on walls has been treated, i wont be lining walls with mylar, i cant be arsed to do it. I'll clean up all the spilled pebbles etc tomorro. Its hard running multiple grows, such a time demanding job. People think its easy and it is when u manage a home grow but it can get frustrating and stressfull wen running a large op. i had to quit a good job to do this and i still dont have enough hours in the day. I spend like 10-14hours sorting out grows, go mma training then see my family for an hour, thats if the kids arent in bed. But im passionate about what i do so the show goes on!
Anyhow Nutrient regime for the flood and drain is:
200litres water
650ml Dutchpro grow (hydro, soft water) A+B
400ml B-52
20ml drip clean
120ml Guardian
500ml Cannazyme
60ml root excellurator
Voodoo Juice
ph 5.6 (dutchpro ph- grow nitric acid)
As u can see from the list the additives are mainly geared to root health. I cant stress the importance of this enough! People worry too much about what is happening above the ground, grow large plants but wonder why yield is so low compared to size of plant. Any good plant needs a large as possible and healthy root mass, thats where the nutrients are taken up. Bottom line is great roots equals great buds!
As u can see in pics cuttings vary in size above the surface but i'll be training plants til the smaller ones are in a more equal playing field.
