Opinions on my setup please?!

I have finally sorted out my set-up and was wondering if anyone had any tips or advice which may help improve it to produce better and higher yield plants.

veg:
bud box medium
250w mh on 18/6
constant 24 C temp
cuttings when rooted are placed in 4" pots using j innes no1/30% perlite for 2 weeks
then transplanted to 5 litre tubs using j innes no2/30% perlite for next 3 weeks.

After 45 days/ 5 weeks they are transplanted to 12.5 litre pots using j innes no3/30% perlite.

Flower:
Bud box large
2x400w hps on 12/12
constant 24 c

nutes being used are biobizz grow/ bloom once in flower. wk1-2 (1ml gr/ 1ml bl), wk2-4 (1ml gr/ 2ml bl), wk4-until browning pistils (1ml gr/ 3ml bl), from browning pistils to finish (2ml gr/ 1ml bl). All amounts are per litre of water. Also dose in Epsom salts if the plant needs it for mag def.

I am currently growning nlxbb and orange bud. Just about to start some chronic from seed.

I think that is everything, if i have missed anything out i will edit this.

Whats the temp like with those cool tubes? Can you touch them with out getting burnt?

How much did you spend on inline fans? i see you have three and there like 200usd a piece.

Nice set-up!!!!!

hi mate. the fans were around £50 each and i only have 2. The cool tubes are hugely cooler than a normal reflector. they still get quite hot up close but you can have the top of the plant like 1" away from the tubes.
