Well what i do is this....

I've got two small poland spring bottles (11oz each)

I fill close to half way (1/3) With hot ass water from the tap

I fill by my eye some sugar (at least a noticable layer on the bottom)

Shake the hell out of em

Oh yea I poke a hole in each cap (about a pen wide)

So then the sugar is disolved and I pour half a packet of yeast in each

I then will squeeze the bottles frequently at least a couple times during the light around the plants...Oh and becareful not to spray the light bulbs or else they will shatter and that is not good

Later on I will start to shake the bottles (with my finger over the hole) and then slowly let my finger off and point to air at the plants....

This will last one bottle this way lasts about 3 days...

I f you dont shake it around frequently youll come back to find it all spewed from the cap and making a mess so be careful on how much you use...

Not sure if this has helped the plants in away but I do it out of love.....Awwww

Peace
-Tek
