having fresh dried herbs all the time is AWSOME!!!
I grow 'em in my veg patch.
Somewhat less exxy than an Aerogarbage.
Have your heard of using carbinated water if you can not affored a Co2 system. If that will not work what else could I do?
CO2 is not worth doing unless done right and it's VERY expensive to do right.
You need to know the concentration of CO2 you are keeping in the atmosphere; to accomplish that, you need to know how much you're applying and the gas has to be kept in the room at the correct levels at all times.
A proper CO2 system has a tank of gas, a regulator and a controller which can measure the gas concentration and control exhaust blowers and air conditioners, so it can replace gas as needed.You won't get away with this for under $1500-2000 or so.
Inexpensive chemical reaction methods of making CO2 (baking soad/vinegar, yeast/sugar) definitely make CO2 but you have
no idea how much. If your exhaust fan runs, out goes your gas. These cheap methods are a waste of time and money. Don't bother.
Roots want O2, not CO2, I don't see the point of carbonated water on the roots. I suppose you could foilar spray with it but the gas would be gone in seconds, not nearly long enough to do any good.
hey .. what about t5 fluoros?
They're still fluoros and will deliver thin, weedy buds.
If you have a small grow, flower with a small HPS. 250W HPS is common as a security light in hardware stores, but HTG Supply sells a proper 400HPS with ballast, lamp & ref for about $120.
Life's too short to grow crappy dope. Get proper lighting and you'll get some nice dense nugs.
