my next grow

hi all ive decided to do another grow in about a months time so heres my plan

i want to get a 32 pod flood and drain system and put polystirene under that to keep it off the cold floor,i will be getting 3 600w mh lights with digital ballasts to start the grow of then change the bulbs to hps when flowering,i will cover the walls and ceiling with mylar,i will feed be growing white widow, there will be 2 aquastic fans 1 200mm and 1 250mm witch 1 should i use for the intake and outtake

i will be feeding the plants with canna hydro vega, flores,rhizotonic,pk13/14,cannazym and boost all canna products

i plan on vegging for 6 weeks from seed then flowering for 8 weeks

has any body grew with white widow,flood and drain dose this snd enough light
also what temperature should the room be and what should the ph level be

any help or advice would be much appreciated

any 1 think this is alright
or any advice

You intake should always be higher than your outtake, so use the larger one for intake.

Plants don't have a calendar, so don't plan ahead how much time vegging and flowering will take. You should induce flowering when your plant has 6-8 internodes (spaces between the nodes - cotyledons not counting) and some 15-20cm (about 6-8 inches) in your case (white widow). It's time to trim when more than 75% of your pistils have turned red/copper/brown and (if you have a microscope) your trichomes turn a red/coppery/brown color.

Since you're running a hydro grow, I'd say that your plant will grow fast (you can veg less that 6 weeks) and a longer flowering (I'd say 9).

Temperatures are ideal between 22-27C during the daytime cycle and 18-20C for the nighttime cycle. Different temps can burn/stun your plants growth. Temps go hand in hand with humidity, which should be high at first (70%), then lowered under 50% during flowering in order to avoid bud rot.

pH in a hydro grow is perfect between 5.5-6.5. You, having a hybrid that is more indica in built should agree the most to a 5.7-5.9 pH.

thanks for the advice mate thats very helpfull
