Under-current xl12 + grobot evolution

So really about to try this out. Well within a mont h or so. Upgrade tu a ucxl12 along with the grobot evloution. and 3k of light. Heard talk of anywhere from half to 2 pounds per site. Anyone feel these are acurate numbers.

2 pounds... Maybe if you have 1k over each plant in a scrog or a light mover or something. That's .9g per watt with a 1k.

I have always been small time with 300w and 400w... so just a guess since no one replied.

Do not run a purgro growbot with an undercurrent.... i swear you will lose your run. The grobot does not work properly and will ruin your ph levels. Trust me i wrestled with 4 different grobot units and could not get one to work properly. Greg from Purgrow is a fraud. It is hard to get a reliable honest review on that product. It will screw up your ph levels guaranteed....the undercurrent is a very finicky system and is complicated enough on its own. Just do your own ph dosing.....dont waste money on the purgrow.
