hydro system?

Hey I have a 4w by 2l by 5h room I want to purchase a small hydro system no bigger than half the room size I want it to be big enough for 3 or 4 plants for sog I've seen one which is a 4 gallon will that be enough for 3 or 4 plants for sog? I'm growing under a 600 watt hps completley sealed room temps 80 to 90 and I'm about to purchase a co2 bag called exhale any input on my hydro question is much appreciate and any added experience with the co2 bag exhale is appreciated also

Unless you have a unlimited amount of co2 bags you going to need to get those temps down. 85 is the max, and that is recommended with constant co2 flow of around 1500ppm. The thing with those co2 bags is you have any control over how much co2 is in your sealed room, since it sounds like its your first grow ditch the co2 all together.

Anyways, in your situation I'd do an ebb & flow system with 6 inch rockwool cubes. You need to get those temps down otherwise its going to stress out or plants. If you absolutely cannot, I'd suggest going a strain that is accustomed to that heat.

I would just get this thing and drop three or four 3.5" net pots in the lid with an air stone in the bottom, and do a 4 site lollipop dwc; probably veg for 2-3 weeks from sprout, until they have 4-5 nodes, then 12/12. I don't think 4 gallons would be enough, but 20 gallons of water in this 27g tote would, and it should be light proof except for maybe the lid. Wrap it up with a few layers of silver bubble wrap for insulation. It is slightly larger than you said you are looking for... if you are looking to grow in a 2x2 area, this will take up a couple inches more than half your space. But it will probably be better than any poorly designed complicated flimsy piece of shit dwc system you can buy off the internet.

Another good choice would be ebb n flow if you don't mind the added complication. Root rot would not be an issue like it can be in dwc if you don't spring for some $15 benes. Another consideration is with ambient temps in the 90s, you will probably need to swap an ice bottle every day if you do a dwc tote. Some people are not up for that much work.

shit... even if you do ebb n flow you could probably use this tote for the res.

Here is a picture of my veg tent. It measures 4' wide, 2' deep, 5' tall. I build these systems. You can too. The 5" fence post and caps are available at Lowes. You can make a res out of any number of totes. For 3 plants I recommend 10 gallons. In my state, as MM patients we're only allowed 3 in veg and 3 in flower so I built accordingly.


Here is a pic of my flowering system. Same length tube. This crop yielded a little over 15 ounces of primo material.
