600w didital

i plan on putting them in 5 gallon buckets they take up 1 foot.i could get 16 in but i was thinking about putting 10 in so each can have some room to spread out during flowering.i was just wondering will i be reducing my yeild per plant because of lumens.im not worried about height seeing that i have an eight foot clearance.if they get that tall i would be on happy farmer.i also want to say thanks to the person who told me me i needed to clone.ididnt now i know how important it is as now i have to start all over and waste alot of time feeding plants that will turn out to be males.for the new ones out there starting to grow it is very important to learn how to do everything.from lst,clone,supercropping,and the most important how to read your plants knowing when something just aint right.that way you can correct the problem and not strees your plants.so this time when my plants are in the 3 week of flowering i will take some clones.you know what thats what im going to do with males.practice how to take clones.what are the best way to do this.can i take cuttings and put them in a bucket of water with airstones unil they grow roots.it will be something like dwc but straight in the solution.
