I've got my 3rd grow (some Skywalker plants) starting flowering now, and I was wondering about adding extra lighting underneath the plants to help the bottom growth.
My last grow I had 9 Granddaddy Purples, and they are a pure indica and get really bushy as they grow. The tops had nice buds and I averaged 1.4 ounces per plant without CO2, but the bottom buds were light and airy and small.
I also had 4 Bubba OGs averaging a bit over 2 ounces per plant, and their bottom growth was smaller than the tops but not as small as the GDP.
These Skywalkers are sativa / indica hybrid from what I'm told, so I don't think they will be as bushy, but I don't want tiny bottom buds again.
My neighbor who grows has told me that bottom lighting will help a lot, and also trimming off the small bottom branches right from the start of flowering will also make the upper buds bigger.
I was at Home Depot last night, and I can pick up some twin T8 4 foot light fixtures for $20 each, plus 2 T8 3000K 4' bulbs for $7. And lay them on the floor between the rows of buckets. So 3 sets of lights will cost me $81 + tax.
Top light is a 1000 watt HPS, with a 400 HPS which will be turned on when the plants get larger.
So would bottom lights be worth it with these plants?
