Expand or finish grow?

Okay this is my first grow so im just gonna let yall help me out here, as in what should I do now because im lost in where to go next


Okay so i paid 150$ for a 5x5x6.5 and 600w hps, i got it all set up got me a hydrofarm GH bucket with some northern lights in there running lucas form, i have one 8 inch 220 cfm just intake, i want to expand but dont entirely know what direction i should go in, i just got her as a clone oct 28 from a dispensary (strain is northern lights if anyone is curious) so with everything i have with the bucket how hard would it be to add another diy one? Or should i just go buy another bucket

If you've never grown weed before starting out doing hydro could challenge your patience. Not an impossible feat just requires some reading. And maybe a few mistakes along the way as you go along the learning curve.
Anyway so it's better to pull the air through your tent rather than push it. Set your inline fan to pull the heat off of the 600w attached to the hood preferably. Then use ducting to pull it into an optional filter to eliminate odors. So what you want is exhaust; not really intake. Fresh air will come in through the holes in your tent. You want to exchange the air in there as much as possible; it's ok if the walls of tent suck in slightly.
Adding another dwc bucket is easy enough just be sure it's totally lightproof. Thick black buckets are usually kinda pricey online because of obvious hydro applications but you could also just spray paint a diy bucket. DIY is much cheaper but buying one already built is less effort. While dwc buckets are easy to diy they are not necessarily "the best" way to grow hydroponically. Check out stinkbuds aero thread in the hydro section; called harvest a pound every three weeks....
Might be a good idea to try just doing the one clone for now and see if hydro is for you before diving in at full speed. I have been through the gauntlet myself doing hydro and found that I actually prefer growing in soil. You can't beat the simplicity of a plant in a dirt pot yet you can't beat the yield you get from hydro. There's pros and cons to both. Get yourself a ph pen and tds; you'll definitely need them.
