great information - Most LED's recommend that one germinates at a lower rate ALSO during one's flush ( if you do one) is recommendated that one's used a lower watt - whic his done to "miminch" natrual daylight during during the fall. Basicly we are talking about light intenity - have been lowering the light to 75% at least during the last few weeks of growth. take a look at yourplants - they just don't look right - lowering the amount of wattage/intensity at end of grow can increase terpene amounts - no sense buruing them up with 100% intensity at harvest. Have just stsarted to lower watt amounts and the plants look better and are healthier. thoughts !!!!!! Note: to high of wattage during germmination can result in issues early onI'm hesitant to crank it to the max of 400 watts as I've read some things saying to keep it a little lower at this young. And they have roommates as we're seeding tomato plants as well.
This is the advice I've seen "40 watts per square foot". My three bags are about a foot in diameter so they each take up a square foot, and the tomatoes next to them take up about 1.5 square feet so I was setting my light as close to 180 watts as I could.
I did increase it to 200 Watts as a test. Worried 400 will fry them.
